Abstract
The valve is for an integral hydraulic pump and valve having a housing to be integral with a pump housing with spaced low pressure and high pressure ports corresponding to the low pressure inlet port and high pressure outlet port of the pump. A low pressure chamber, a high pressure chamber and a cylinder chamber in the housing are spaced apart and parallel to one another. A transverse bore in the housing intersects the chambers. A valve is movable axially in the bore having an annular groove intermediate its ends capable of connecting the low pressure and high pressure chambers in a first neutral position, capable of connecting all of the chambers in a second position and connecting only the low pressure chamber in a third position. Detents in the housings extend into the bore and annular groove in the valve.
