Housing portion for e.g. diesel injection pump of fuel injection system, has high pressure valve whose valve element is guided over connector that is gripped non-positively and/or positively with portion through high pressure bore

摘要

The portion (1) has a cylinder head in which a high pressure valve (3) i.e. non-return valve, is formed with a high pressure bore (2) as a high pressure outlet. The pressure valve comprises an axial displaceable valve element (4), which possesses a front-sided cap-shaped seal surface (6) cooperating with a valve seat (5). A spring force of a spring (7) is applied toward the seat. The valve element of the high pressure valve is guided over a connector (8) that is gripped non-positively and/or positively with the portion through the high pressure bore.
