ABSTRACT:
In order to reduce noise within a hydraulic pump of a type having a cylinder barrel defining a plurality of piston bores with the cylinder barrel being rotatable relative to a cylinder head having a valve face for periodically communicating the piston bores with inlet and outlet ports, the valve face is designed to provide overlapping alignment of each piston bore with the inlet passage at a bottom dead center position, subsequent communication of the bore with the outlet port being initiated by a bleed slot. Additionally, the valve face is configured for developing increased clamping engagement between the cylinder barrel and cylinder head by selective communication of each bore with the outlet and inlet ports at a top dead center position. The valve face configuration improves lubrication of the pistons.
