Summary: Schematic layout of a hydraulic system.
Description: Primitive cable linkages in aircraft are briefly compared with hydraulically operated controls. The underlying principle of hydraulic systems - a large diameter piston driven by a small bore piston or pump - is described and a car is shown being raised on a hydraulic platform. A very simple hydraulic system is then gradually built up and refined from first principles in diagram form, incorporating a reservoir, hand pump, safety valve, piston and sliding selector valve unit.
