Patent ID: 7025292

Claim:
Injector to inject fuel into a combustion chamber comprising an actuator housing and an injector housing, wherein the injector housing comprises an indentation in which a part of the actuator housing is located, a bottom surface of the indentation of the injector housing is formed by a peripheral support surface for the actuator housing, a seal is located between the injector housing and the actuator housing to prevent leakage along interfaces between injector housing and actuator housing, an underside of the actuator housing that is adjacent to the support surface of the injector housing comprises a peripheral recess, the recess of the underside of actuator housing is such that the underside of actuator housing comprises at least one peripheral projection which is oriented towards the support surface of the injector housing and is adjacent to the support surface of the injector housing, the diameter of the peripheral projection at a beginning of the peripheral projection being smaller than the diameter at a proximate end of the peripheral projection, and wherein the seal is located in the recess of the underside of the actuator housing and is stretched around the projection of the underside of the actuator housing and adjoins the support surface of the injector housing.
