ABSTRACT:
An axial-piston variable-delivery pump with a valve directional control of the pressure fluid flow comprising a housing with an intake manifold, at least one pressure manifold and a pressure fluid admission duct. Axial borings in the housing accommodate oppositely arranged pistons capable of undergoing reciprocating motion and adapted to cooperate with driving members on the drive shaft. The pistons establish delivery chambers in the pump housing, each of them in communication with the pressure manifold through a delivery valve, and with the intake manifold through an inlet valve. The actuator spindle of the inlet valve is adapted to interact with a plunger mounted coaxially with the inlet valve and defines, together with the boring in the pump housing, a chamber in communication with a shaped surface of a cylindrical sleeve which embraces the drive shaft and is interconnected therewith for cooperative rotation. The sleeve is accommodated in an axial boring of the housing and is axially movable therein such that the depressions and the lands on the outer surface thereof define individual zones in the pump housing. One of these zones is in permanent communication with the exhaust line, while a second zone is in communication with the pressure fluid admission duct. Another plunger adapted to cooperate with the first, is accommodated in at least one of the chambers defined by the boring and the first plunger coaxially with the latter. Another duct is provided in the pump housing to admit pressure fluid to each of the zones of interaction of the plungers.
