    摘要： The invention relates to a high pressure pump for a common rail pump system and to a common rail pump system. A high pressure pump (2) for a common rail pump system comprises a pump body (4) having a cylinder (6) with a piston bore (8) and a piston (10) reciprocally driven in the piston bore (8) by an eccentric to pressurize fuel in the cylinder (6). The piston (10) comprises an inner end (12) located in the piston bore (8) and an outer end (14) outside the piston bore (8). A bellow (20) having a first opening (22) and a second opening (24) is arranged between the piston (10) and the pump body (4), wherein the piston (10) extends through the first opening (22) and the second opening (24), wherein the bellow (20) is connected to the pump body (40) such that the first opening (22) is sealed on the pump body (4, 50) and wherein the bellow (20) is connected to the outer end (14) of the piston (10) such that the second opening (24) is sealed on the piston (10). This prevents mixing of engine oil and fuel, when the pump is directly attached to an engine. The bellow may be connected to a drainage line over a one-way valve.

    摘要： The invention relates to a check valve comprising a valve body (1) provided with a valve seat (2) formed in the valve body (1), a valve plunger (4) which is guided in a guiding borehole (3) of the valve body (1), and a valve disk (5) which is embodied on the valve plunger (4) and can be applied to the valve seat (2) arranged in the valve body (1) in a sealing manner. The admission (6, 7) to the check valve (1) is carried out by means of at least one supply groove (6) embodied in the front side (8) of the valve body (1), opposing the valve seat (2), and at least one supply borehole (7) formed in the valve body (1). The inventive check valve (20) is especially suitable for a radial piston pump for the high-pressure supply of fuel in fuel injection systems of internal combustion engines.
