Hydraulic Video Series
Hydraulic Symbols

This video was produced by JI Case to teach the technician/student how to read hydraulic schematics. The video uses line drawings and cut-away views to illustrate how symbols are used to represent hydraulic components. Animations are used to explain how visualization is employed to understand the operating function of a component represented by a one-dimensional symbol. Once these concepts are understood, hydraulic circuit drawings become easier to understand.

The following symbols are illustrated and explained:

	Reservoirs
	Lines, tubes, hoses
	Enclosures and connections
	Pumps, fixed and variable, pressure compensated and manual control
	Motors
	Cylinders - with and without cushions
	Pressure relief, pressure reducing and sequence valves
	Directional control valves
	Flow control valves, fixed and adjustable, pressure and temperature compensated
	Filters, coolers, heaters and accumulators
