Hilmar, repeating your answer several times doesn't make it any more comprehensible. The handle on the hydraulic jack is a lever that gives the kid a mechanical advantage when used to propel a little hydraulic fluid from a reservoir to the movable platform supporting the vehicle. The jack mechanism prevents the hydraulic fluid from returning to the reservoir when the lever is raised for another stroke. Thus, each downstroke pushes more oil out to the platform, and up it goes. An automobile jack is sized to lift autos, but heavier objects need larger jacks or more of them.
Hydraulic (mean) detph is the flow area divided by the water surface lenghth. It is the average..
The operating pressure is 62.4mpa and the net weight is 31.3kg if the stroke length is 200mm and o.d is 140 mm
There is no opposite machine to a pulley. However, a jack or hydraulic lift essentially does the reverse, lifting from below rather than from above.
sity hydraulic fluids
No, not really. Force in hydraulics is only dependent on the force applied to the fluid and the surface area of the hydraulics piston and can be calculated by force in fluid*surface area. This means that the bore which is directly related to the surface area of the hydraulic piston helps to determine the lifting capacity of a hydraulic jack, but that the stroke of the hydraulic jack does not. There are a few reasons however why hydraulic jacks that have a higher lifting capacity might have a shorter stroke. First of all, the greater the surface area of the hydraulic used on the lift, the more fluid must be pumped to raise the lift a certain distance, so you would need more fluid to raise the lift a certain distance. Also, when designing such a mechanism the engineers might have considered the horizontal load on the hydraulic's piston, that might bend it more if the stroke were longer.
Hydraulic Jack oil
Open the drain screw that holds the body of the hydraulic jack. This way you can addhydraulic oil to the hydraulic jack.

hydraulic brake and hydraulic jack
The operation of the pump in a hydraulic jack is to generate pressure. This causes the jack to rise and lift as needed.

They are hydraulic and are not adjustable
The hydraulic jack is fabricated in pieces and is inserted into the actual hydraulic breaking system of the vehicle. Unions and ball valves along with a directional control valve allow the jack that is mounted on the chassis to be activated with brake pedal access.
