ABSTRACT:
An oil pump is disclosed having a pressure pipe which is coaxially disposed within a suction pipe to provide a shielding of the pressure pipe. Both the suction pipe and the pressure pipe are arranged parallel to a vertical axis of a housing of the pump. An oil-jet ejector is connected to the interior of the pump housing through openings which provide a continuous venting of the oil flow within the pump. The venting is provided on both the intake and discharge ends of the pump.
