Fuel injection valve e.g. for fuel injection systems, has excitable actuator for manipulation of valve which together with valve seat body forms sealing seat for valve seat surface

摘要

u The fuel injecting valve (1) has an excitable actuator (10) for the manipulation of a valve (4), which together with a valve seat body (5) forms a sealing seat for a valve seat surface (6). Openings (7) are provided in the valve seat body. In a direction of flow between a sealing seat line (40) at the valve seat surface and the openings an elevation (38) is provided. The elevation has an internal front surface (37) towering above the valve seat body having a ramp shaped rise.
