Functions of relief valves in fluid power control systems?
Fluid power comes in two forms: hydraulic and pneumatic. The pump in an hydraulic system is a flow source, delivering a set amount of fluid every revolution. Pressure is an effect due to restriction on flow in the circuit. If the oil delivered by the pump is used to operate a cylinder, the pressure that develops is due to load on the piston. If the pressure required to move the load on the cylinder is greater than the setting of the relief valve, the piston will not move and all the oil will pass through the relief valve. Also, when the piston has moved to the end of the stroke, it cannot move any further, however the oil delivered by the pump goes over the relief valve. If there wasn't a relief valve, the pressure will build up until the oil from the pump can flow somewhere: by bursting a hose or breaking the pump or cylinder.
What does the actuator do?
The most common actuator is a hydraulic actuator or an electro-servo actuator. These are linear actuators that move a piston rod to a set stroke and force. It is used to push and pull at a fixed length(stroke) and force. Used in conjuction with rods and cranks, the actuator can be used to move controls through variable geometry such as arcs. The Hydraulic Actuator has a piston internal to the housing. The hydraulic pressure is ported on one end and forces the piston to move to the opposite end, which pushes the rod to extend it. Reversing the hydraulic pressure(or applying it at the other side of the piston) will cause the rod to stroke back to original position. The force that is available is equal to the hydraulic pressure times the area of the piston.
Difference between set pressure and blow-off pressure?
The set pressure is the pressure at which a relief valve starts to open. When the valve is open and relieving, the pressure will be higher or lower than the set pressure, depending on the system and the valve design. That is the blow-off pressure.
What is the least count of slip gauge set?
.001mm
What is a fixed reference point?
A set point where all measurements can be taken from
Is timing set on exhaust or intake stroke?
Neither, on a 4 cycle engine the timing is set at the end of the compression stroke of the number 1 cylinder.
How do you line up the timing chain marks on 1995 land rover 3.9l v8?
Set your #1 cylinder to TDC on the compression stroke.
How to set the timing on a 350 engine?
Remove the number one spark plug, last cylinder on the right rear bank (passenger side) bring the cylinder to top dead center on compression stroke, check the rotor on the distrubitor making sure it is pointed to number one cylinder. Now you can set the timing with a vacum gauge for the best vacum, or using a timing light you can set the timing (?) degrees, depending on which year you have, firing order 18436572 NEW ANSWER : SORRY, but the answer above is all wrong. You cannot use a timing light on that year engine. The timing is computer controlled and you MUST use an OBDII engine scanner to set the timing.
Can the timing be set on a 1996 Nissan 4x4 with a 4 cylinder engine or is it electronic?
Yes the timing can be set.

HOW DO I SET DISTRIBUTION TIMING ON NISSAN 1400?
To set the distribution timing on a Nissan 1400, you need to first ensure the engine is at top dead center (TDC) on the compression stroke for cylinder one. Then, align the timing mark on the crankshaft pulley with the timing pointer on the timing cover. Next, adjust the distributor so that the rotor points to the number one cylinder terminal in the distributor cap. Finally, tighten the distributor hold-down bolt and double-check the timing with a timing light if necessary.
You put a 1975 350 in your 1986 half ton and you can not get it to start only fire pops out of the carb what do you do next?
Sounds like it is out of time, check the mark on the crank and number one cylinder and distributor. their is a compression stroke and exhaust stroke so be sure you are one the compression when checking timing. Sounds like it is out of time, check the mark on the crank and number one cylinder and distributor. their is a compression stroke and exhaust stroke so be sure you are one the compression when checking timing. This condition defines a intake valve is open when the spark plug fires. Look to see if the plug wires is properly connected in the right firing order. If the engine has been disassembled the vale timing could not be set proper. Ignition timing may not be set to the right position. Timing mark at TDC. Cylinder number 1 on compression stroke.Drop distributor in with rotor facing cylinder number 1 on distributor cap.
Set the timing on 2000 Toyota 2.2 liter 4-cylinder?

Before top dead center?
This refers to when the spark plug fires on number one cylinder. All cylinders will fire at the same point in the stroke, but number one is used to set the timing. There is a notch or line on the crankshaft pulley that marks when the number one piston is at the top of the stroke. The timing is set before TDC so that the fuel can ignite before the piston reaches the top of the cylinder. This gets the most out of the explosion of the fuel. Timing is different for each make of engine, but usually 6-8 degrees before TDC.
How do you set timing marks for 2005 Chevy aveo?
To set the timing marks on a 2005 Chevy Aveo, first ensure the engine is at top dead center (TDC) on the compression stroke for cylinder one. Locate the timing marks on the crankshaft pulley and the timing cover; align the mark on the crankshaft pulley with the TDC mark on the cover. Next, check the camshaft timing marks, ensuring they are aligned properly with the corresponding marks on the cylinder head. If necessary, adjust the timing belt or chain to ensure all marks are aligned correctly.

Set timing 94 Lexus sc300 3.0 motor?
To set the timing on a 1994 Lexus SC300 with a 3.0L engine, first ensure the engine is at top dead center (TDC) on the compression stroke for cylinder one. Then, align the timing mark on the crankshaft pulley with the timing indicator on the timing cover. Adjust the camshaft timing by aligning the camshaft timing marks, ensuring they are level with the cylinder head. Finally, check and adjust the ignition timing using a timing light, setting it to the specified degrees before top dead center (BTDC) as indicated in the service manual.
