An axial-piston pump has a drive shaft installed in the inner cavity of the housing, with bushing, pistons with toes placed in axial borings of the housing, those are pressed with pressing discs to inclined dicks, suction valve and supercharge valve. Between the placed in opposite positions pistons in radial borings of the housing supercharge valve is placed, its ram is connected to the ram of the suction valve that is installed to hydro-pusher. The hydro-pusher is connected with profiled surface of distribution bushing that is placed on the drive shaft with possibility of axial displacement and is connected through a pin to the drive shaft and a con-rod, this is connected to the mechanism of working fluid supply change. On the outer surface of distribution bushing slots are provided, those are restricted with links and form zone of control pressure feeding to the ram of suction valve and zone of connection to discharge cavity. |
