<p>The rotary and axial piston pump with a cylinder and piston system alternately connecting with a suction opening and opposed working chambers (19), has an additional opening (14) suction and pressure openings. Each working chamber which is brought into the region in the zone of the communicating part (23) between the openings (12, 13) of the distributor disc (6) is in connection with the additional opening at given instants. The opening is in connection with a reservoir chamber (16) connected by a throttling opening (18) with the pressure opening (13). This additional opening (14) is at one end of the distributor disc (6) radial to the suction and pressure openings outside the edge of opening (20) of the working chamber (19) of the cylinder block (3).</p> |
