Hydraulic Cylinders

A Hydraulic Cylinder is a device for converting pressure change into mechanical motion. The cylinder has two chambers separated by a piston. A hydraulic pump generates a pressure difference between the chambers by alternately filling (push stroke) and removing (pull stroke) fluid from each chamber. This pressure difference creates motion of the piston inside the cylinder body. A piston rod is attached to the piston and behaves as a linear actuator in response to the movement of the piston.
