the pump supply's the pressure, the resivoir supply's the fluid, the valve dirercts the fluid into the cylinder, to extend or retract the cylinder.

How do you connect a lock valve to hydraulic cylinder?

The lock valve is connected to a hydraulic cylinder by forcefully pressing it into the fitting and releasing the retaining ring. This will lock the cylinder into place and keep it from moving.

How do you bleed hydraulic clutch on 1993 ford escort lx?

Hydraulic clutches use a slave cylinder mounted at / on the transmission to operate the clutch lever. It has a bleeder valve much like a brake wheel cylinder or brake caliper. It typically shares the fluid in the brake fluid reservoir. Use penetrant to minimize the risk of shearing the bleeder valve. Once the valve is working, use the same sequnce to bleed as for brakes. Depress the clutch, open the valve, close the valve, release the clutch, repeat till clear fluid (no old fluid which is YELLOw) and no air, flows. REFILL THE RESERVOIR as needed.

What is the function of a relief valve and what is the disadvantage of it?

A relief valve is spring loaded valve that when excessive hydraulic or air pressure is applied it pushes the cylinder in the direction of the spring and lets the oil or air pass through and escape via another hose returning to the hydraulic tank or into the atmosphere in the case of air pressure. Without it hydraulic pipes or cylinders would rupture.

1999 hino fe how to bleed hydraulic clutch?

gravity bleed the slave cylinder. then use a brake bleeder pump to pump fluid into the slave cylinder's bleeder valve. you will have to use a tool or turkey baster to remove the excess fluid from the reservoir and you pump the bleeder to prevent it from over flowing. do not reuse this fluid.

If a hydraulic reservoir is pressurized to twenty-five psi what would be the minimum pressure in psi in the return line to the reservior?

You would not 'normally' pressurise the reservoir (tank). From the resservoir the oil would go to the pump (be pressurised then) and then on to the function (normally through a valve) after that it goes back to the reservoir. This applies to an 'open' hydraulic circuit. If it it is a 'closed' (loop) circuit the pressuried oil goes back to the other side of the pump to 'feed' it; the reservoir is just to make up any losses and to dissipate heat. It really does depend on your application

How does a 4 way hydraulic valve work?

4 Way hydraulic valves are often used with double acting cylinders. The valve usually has a handle that is used to change fluid direction. On the 4 way valve there will typically be 4 ports or openings for connections of hoses. Connecting hoses is done as follows: There will be an IN and OUT port and there will be an A and B port. (Different manufactures label differently so sometimes ports A & B are labeled 1 & 2 for example.) The in port is where the hose for fluid under pressure is connected. This may be from a hand operated or motor powered pump. The out port will be connected to the hose going to the fluid reservoir or tank. The A and B ports will be connected to the hydraulic cylinder. Now for the how it works part: Basically the handle controls a piston inside the valve. The piston is machined to allow fluid to run through it in different directions depending on the location inside the valve. There are two fluid paths inside the valve at the same time with fluid running two directions. One path is for the supply hydraulic fluid and one path is for the returning hydraulic fluid. When hydraulic fluid is pumped into the IN port and the handle is pushed one direction the fluid passes from the IN port and goes out the A port leading to one line or hose to the hydraulic cylinder. At the same time the valve allows fluid returning from the other hydraulic hose connected to the cylinder to come into port B and go out the OUT port on the valve back to the hydraulic tank. When the handle on the valve is pushed the opposite direction the fluid paths switch so the pumped fluid coming in the IN port goes out the B port to the hydraulic cylinder and fluid returns coming into the A port and goes through the OUT port back to the hydraulic tank. The 4 way valve allows fluid to run from the pump or (hydraulic fluid source) to the hydraulic cylinder in two different directions depending on the position of the handle so the cylinder can either be extended or retracted. When the handle on a valve is not pushed in either direction it is called a neutral or normal position. Some 4 way directional valves only allow fluid to pass when the handle is moved in one direction or the other while some allow the fluid to come into the IN port and go through to the OUT port when it is in the neutral position. The valves that allow fluid to pass from the IN to the OUT while in the neutral position are often used with powered hydraulic pumps. Once the pump is turned on the fluid begins to flow in and out of the valve until the handle is moved to direct fluid to the hydraulic cylinder.

Where and how do you adjust the clutch on a 94 escort?

The clutch can't be adjusted. It is an hydraulic clutch. The clutch pedal sends pressure from the master cylinder to the slave cylinder on the clutch. IF you are having trouble with it the thing to do is bleed the air out at the slave cylinder. Have an assistant pump the clutch and hold it to the floor. Then open the bleed valve on the slave cylinder to let the air out of the system. On the final bleed hold the clutch to the floor and close the bleed valve on the slave cylinder. The clutch master cylinder operates of the brake fluid reservoir. Make sure you keep this full of brake fluid as you bleed the clutch.

What things use pressure to work?

1) hydraulic elevator:Hydraulic elevator systems lift a car using a hydraulic ram, a fluid-driven piston mounted inside a cylinder. You can see how this system works in the diagram below.The cylinder is connected to a fluid-pumping system(typically, hydraulic systems like this use oil, but other incompressible fluids would also work). The hydraulic system has three parts:A tank (the fluid reservoir)A pump, powered by an electric motorA valve between the cylinder and the reservoirThe pump forces fluid from the tank into a pipe leading to the cylinder. When the valve is opened, the pressurized fluid will take the path of least resistance and return to the fluid reservoir. But when the valve is closed, the pressurized fluid has nowhere to go except into the cylinder. As the fluid collects in the cylinder, it pushes the piston up, lifting the elevator car.When the car approaches the correct floor, the control system sends a signal to the electric motor to gradually shut off the pump. With the pump off, there is no more fluid flowing into the cylinder, but the fluid that is already in the cylinder cannot escape (it can't flow backward through the pump, and the valve is still closed). The piston rests on the fluid, and the car stays where it is.2) using ice skates instead of normal shoes: the shoe distributes the force over a much larger area than the skates does. this means that the skates exerts a much higher pressure on the ice than the shoe does- this high pressure makes ice skating possible.

What is a hydraulic float valve?

Hydraulic float valves on earth moving equipment allow the operator the ability to contour the landscape and improve the final grade with certain implements, such as dozer blades, by providing continuous, controlled hydraulic pressure to the raise side of the lift cylinder. In addition to producing the desired result a hydraulic valve in the float position saves horsepower by not "digging-in" and reduces wear on any ground-engaging components.

How does a hydraulic pressure reducing valve work?

A hydraulic pressure reducing valve works by allowing hydraulic fluid to be released. This hydraulic fluid is then chambered separately until it is needed again. The valve is turned either left or right to either build pressure or take pressure away.

Hydraulic power pack for hydraulic press?

Hydraulic power pack are stand-alone devices, as opposed to a built-in power supply for hydraulic machinery. Some power packs are large, stationary units and others are more portable. They have a hydraulic reservoir, which houses the fluid, regulators that allow users to control the amount of pressure the power pack delivers to a valve, pressure supply lines and relief lines, a pump and a motor to power the pump.FunctionHydraulic power packs typically offer a choice of valve connections, allowing users to connect them to a control valve or valves to power a variety of machines. The power pack supplies hydraulic power through a control valve to run another machine.MaintenanceHydraulic power packs need regular maintenance to extend their life and to allow safe operation. Maintenance includes checking the tubing for dents, cracks or other problems, changing the hydraulic fluid and checking the reservoir for rust or corrosion.
