ABSTRACT:
A hydraulic control unit for a motor vehicle having a motor providing a drive shaft driving a rotatable piston bearing surface at a proximal end of the motor, a hydraulic block providing cavities housing a pumping assembly and fluid control valves, and a control section providing solenoid coils receiving portions of the fluid control valves, with the pump cavity being disposed on a first end of the hydraulic block and the valve cavities being disposed on an opposite end of the hydraulic block, and the pumping assembly being reciprocalably driven by the rotatable piston bearing surface along an axis radially disposed from and otherwise parallel to the axis of rotation of the rotatable piston bearing surface. In another aspect, a pump element having a ball bearing assembly mounted at an oblique angle with respect to the axis of rotation of a seat, and a pumping assembly reciprocally bearing against an outer portion of the ball bearing assembly.
