   Hydraulic power pack; Transmission lines Hydraulic hoses; Passive components Hydraulic cylinders; For the hydraulic fluid to do work, it must flow to the actuator and/or motors, then return to a reservoir. The fluid is then filtered and re-pumped. The path taken by hydraulic fluid is called a hydraulic circuit of which there are several types.
