The unit (10) has a pump housing encompassing first and second housing parts (11, 17), where inlet valves (25, 27) are active between pump cylinders (12, 13) and a suction channel (18) and outlet valves are active between the pump cylinders and a pressure channel of the second housing part. The inlet valves encompass an interior in which a valve ball (43) is arranged. The interior is defined by one of the housing parts at a location and by a different part i.e. bushing part, at a different location. The valve ball is supported to freely move in the interior. The inlet valves and the outlet valves are springless ball check valves. |
