Injector to inject fuel into a combustion chamber

摘要

An injector housing ( 1 ) of the injector has an indentation ( 2 ) in which a part of an actuator housing ( 4 ) of the injector is located. A floor of said indentation ( 2 ) is formed by a peripheral support surface ( 3 ) for the actuator housing ( 4 ). A bottom surface of the actuator housing ( 4 ) is oriented towards the support surface ( 3 ) and has a peripheral recess ( 11 ). This recess ( 11 ) is such that the bottom surface of the actuator housing ( 4 ) has at least one peripheral projection ( 12 ), which is oriented towards the support surface ( 3 ) and is adjacent to the support surface ( 3 ). A seal ( 13 ) for preventing leakage along interfaces between the injector housing ( 1 ) and the actuator housing ( 4 ) is locate din the recess ( 11 ) and is adjacent to the support surface ( 3 ).
