Injection device for an internal combustion engine comprising such an injection device

摘要

The device has a fixation unit comprising a fork (24) and a screw (22) for assembling an injector (1) on an internal combustion engine. The fork is made of stratified composite. The fork has metallic layers (241-245) stacked with respect to each other and connected by respective films (246-249), phenolic resin layer or phenolic resin based organic-matrix composite. The films are made of viscoelastic material for permitting dissipation of vibratory energy by damping effect.
