Hydraulic module for fuel injector utilized for injecting fuel into combustion chamber of internal combustion engine, has elastic spring sleeve supported at plate and at area of adjusting piece, where area projects over coupler sleeve

摘要

The module has an adjusting piece (20) that lies at a side of a coupler sleeve (16) such that a coupler gap (22) is formed between the adjusting piece and an actuator-sided end (14) of a valve rod (10), where the side is turned away from a valve plate (4). The coupler gap is limited in a radial direction by the coupler sleeve. The adjusting piece projects in the radial direction over the coupler sleeve. An elastic spring sleeve (36) is supported at the valve plate and at an area of the adjusting piece, where the area projects over the coupler sleeve.
