Abstract

See full text

A hydraulic control valve is disclosed which is adapted to independently control the flow of hydraulic fluid to several consumer lines. The control valve includes a housing having a central bore, a pair of axially spaced apart consumer lines comunicating with the bore, a tank line communicating with the bore and positioned between the consumer lines, and a pair of hydraulic inlet lines communicating with the bore on the outer side of respective ones of the cosumer lines. A pair of slide valves are positioned in the bore, and each slide valve is supported in a neutral position by a coil spring. The two slide valves may be independently moved from their neutral position by a hydraulic control system, so that each slide valve is adapted to selectively establish communication between one of the consumer lines and the tank line, and between such consumer line and one of the hydraulic inlet lines.
