   In the example above of the dump truck, the weight of the dump body, now raised at an angle of 60 degrees but empty of the load, must be enough to force the unpressurized hydraulic fluid out of the cylinder and cause it to retract to the fully collapsed position. [6] Spider lift set up outside a building.

3. Car hydraulics - Wikipedia

   With these modifications, the body of the car can be raised by remote control. The amount and kind of hydraulic pumps [1] being used and the different specifications of the subject vehicle will affect the impact of such systems on the height and orientation of the vehicle. With sufficient pumps, an automobile can jump and hop upwards of six ...

4. Hydraulic cylinder - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_cylinder

   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. The piston pushes the oil in the other chamber back to the reservoir.

5. Piston - Wikipedia

   en.wikipedia.org/wiki/Piston

   Pistons of Hydraulic cylinders used in a hot press. Hydraulic cylinders can be both single-acting or double-acting. A hydraulic actuator controls the movement of the piston back and/or forth. Guide rings guides the piston and rod and absorb the radial forces that act perpendicularly to the cylinder and prevent contact between sliding the metal ...

6. Hydraulic pump - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_pump

   A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. They generate flow with enough power to overcome pressure induced by a load at the pump outlet.

7. Single- and double-acting cylinders - Wikipedia

   Typical horizontal steam engine with double-acting cylinder. A double-acting cylinder is a cylinder in which the working fluid acts alternately on both sides of the piston. . In order to connect the piston in a double-acting cylinder to an external mechanism, such as a crank shaft, a hole must be provided in one end of the cylinder for the piston rod, and this is fitted with a gland or ...
