Exhaust valve for e.g. high pressure diesel injection pump, has valve element designed such that axial displacement between longitudinal axis of outlet hole and valve seat is compensable over valve element

摘要

The valve has a valve element (2) displaced and/or stored in an outlet hole (1), where the valve element is provided with a valve seat (3) with a cap-shaped seal surface (4). The valve element is provided with a guide bushing (5) and a valve closure member. The valve element is designed such that an axial displacement between a longitudinal axis of the outlet hole and the valve seat is compensable over the valve element. The valve element is made of metal or plastic e.g. fiber reinforced Polyether ether ketone.
