ABSTRACT:
An axial plunger pump includes an auxiliary plate mounted to a cam plate at an end thereof on the side of a cylinder block to be rotatabe relative to the cam plate, and a flexible partition member interposed between a housing and the auxiliary plate to cover a drive shaft and the cam plate. The flexible partition member, which is in the form of, e.g. a metal bellows, serves to divide the inside of the housing into a working fluid chamber and a lubricant chamber.
