Abstract
A pump assembly comprises a hydraulic fluid pump having a housing assembled from a plurality of housing components that are pinned together rather than being clamped together by bolts. The pump is disposed in a cavity in a valve block so that the outlet fluid pressure from the pump is applied axially to the housing components to create a greater external axial force on the pump components than the internal axial force and thereby maintain the housing components in tight, sealing relation without the need for clamping bolts or other clamping means.
