2. Hydraulic cylinder - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_cylinder

   A hydraulic cylinder (also called a linear hydraulic motor) is a mechanical actuator that is used to give a unidirectional force through a unidirectional stroke. [ citation needed ] It has many applications, notably in construction equipment ( engineering vehicles ), manufacturing machinery , elevators , and civil engineering.

3. Electrohydraulic servo valve - Wikipedia

   en.wikipedia.org/wiki/Electrohydraulic_servo_valve

   A servo valve receives pressurized hydraulic fluid from a source, typically a hydraulic pump. It then transfers the fluid to a hydraulic cylinder in a closely controlled manner. Typically, the valve will move the spool proportionnaly to an electrical signal that it receives, indirectly controlling flow rate.

4. Hydraulic machinery - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_machinery

   Directional control valves are usually designed to be stackable, with one valve for each hydraulic cylinder, and one fluid input supplying all the valves in the stack. Tolerances are very tight in order to handle the high pressure and avoid leaking, spools typically have a clearance with the housing of less than a thousandth of an inch (25 μm).

5. Position-sensing hydraulic cylinder - Wikipedia

   en.wikipedia.org/wiki/Position-sensing_hydraulic...

   A position-sensing hydraulic cylinder is a hydraulic cylinder with an integrated position feedback sensor to determine its current position. Position-sensing hydraulic cylinders may be found in heavy industry , subsea , and mobile heavy equipment applications.

6. Telescopic cylinder - Wikipedia

   en.wikipedia.org/wiki/Telescopic_cylinder

   Telescopic cylinders must only be used in machinery as a device for providing force and travel. Side forces and moment loads must be minimized. Telescopic cylinders should not be used to stabilize a structural component. [4] Hydraulic telescopic cylinders are often limited to a maximum hydraulic pressure of 2000-3000 psi.
