Fuel injection valve for air-compressing self-igniting internal combustion engine i.e. diesel engine, has transition piece with front side facing both contact surface of guide plate and front side of plunger rod

摘要

The valve (1) has a plunger rod (36) guided in a guide plate (4) and operated by a piezoelectric actuator (3). A compensator (51) is supported at a contact surface (52) of the guide plate, and rests at a front side (53) of the plunger rod and at a front side (54) of a transition piece (8) adjustable by the actuator. The front side of the transition piece faces both the contact surface of the guide plate and the front side of the plunger rod. The plunger rod lies at a front side (21) of a multiplying piston (20).
