Abstract:
An improvement of an inclined shaft-type variable displacement pump/motor
in which pistons reciprocate in cylinders. A valve plate member is constructed
from valve plates having a first valve plate and a second valve plate. The valve
plate member is interposed between a block-side sliding surface of a cylinder
