2. Telescopic cylinder - Wikipedia

   en.wikipedia.org/wiki/Telescopic_cylinder

   An application for telescopic cylinders commonly seen is that of the dump body on a dump truck used in a construction site. In order to empty the load of gravel completely, the dump body must be raised to an angle of about 60 degrees. To accomplish this long travel with a conventional hydraulic cylinder is very difficult considering that the ...

3. Hydraulic cylinder - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_cylinder

   A hydraulic cylinder is the actuator or "motor" side of this system. The "generator" side of the hydraulic system is the hydraulic pump which delivers a fixed or regulated flow of oil to the hydraulic cylinder, to move the piston. There are three types of pump widely used: hydraulic hand pump, hydraulic air pump, and hydraulic electric pump.

4. Hydraulic motor - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_motor

   The hydraulic motor is the rotary counterpart of the hydraulic cylinder as a linear actuator. Most broadly, the category of devices called hydraulic motors has sometimes included those that run on hydropower (namely, water engines and water motors ) but in today's terminology the name usually refers more specifically to motors that use ...

5. Hydraulic machinery - Wikipedia

   The pump swivel angle covers both positive and negative flow direction. Disadvantages: The pump cannot be utilized for any other hydraulic function in an easy way and cooling can be a problem due to limited exchange of oil flow. High power closed loop systems generally must have a 'flush-valve' assembled in the circuit in order to exchange much ...

6. Auxiliary hydraulic system - Wikipedia

   en.wikipedia.org/wiki/Auxiliary_hydraulic_system

   Vehicle interface fittings, length from pump to attachment and vehicle control systems require various configurations of an auxiliary hydraulic system. Auxiliary hydraulic systems usually include external fluid fittings to facilitate connecting and disconnecting the hydraulic fluid supply lines of the attachments to the vehicles' hydraulic pump.

7. Hydraulic ram - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_ram

   A hydraulic ram pump, ram pump, or hydram is a cyclic water pump powered by hydropower. It takes in water at one " hydraulic head " (pressure) and flow rate, and outputs water at a higher hydraulic head and lower flow rate.
