International Classification:

F01L 2506

US Classification:

91307

Abstract:

A control valve for alternately applying fluid pressure to two drive members of a reciprocating work device such as a pump. A valve piston is slideable in a closed cylinder to which pressurized fluid is transmitted. The valve piston, controls the fluid depending on the position of the piston in its cylinder, to pressurize one chamber and vent the other so as to move the work device in one direction or the other. In turn, the work device controls the fluid to position the valve piston.
