ABSTRACT:
The invention relates to a hydrostatic power steering unit of the type having a gerotor gear set forming a metering motor and a valve unit for routing pressurized fluid from an inlet port selectively via expansible chambers of the gerotor gear set to either one of two motor ports while connecting the other one of the motor ports to an outlet port. The housing of the valve unit, which has inner and outer rotary sleeve members, is arranged adjacent the gerotor gear set. A cardan shaft which connects the outer sleeve member to the gerotor star member has a gear head connected to the adjacent end of the outer sleeve member but the shaft itself is disposed mostly in the gerotor star member. The bore of the inner sleeve member has a smaller diameter than that of the shaft head connected to the outer sleeve member and the annularly and axially extending valving grooves of the inner valve member may thus have relatively greater radial depths and thereby relatively greater capacity.
