Valve e.g. injecting valve, for use in e.g. fuel injecting system, has valve housing, valve seat carrier, valve needle with valve closure unit, and valve closure spring, where one of above components is made of fiber-reinforced material

摘要

The valve has a valve housing (11), a valve seat carrier (16), a valve needle (15) with a valve closure unit (20), and a valve closure spring (25). The valve closure unit combines with a valve seat (22) at the valve seat carrier. The valve closure spring is pressed to the valve seat at the valve closure head (23). One of the above valve components is made of a fiber-reinforced material. The valve needle is adhesively connected with an anchor of an electromagnetic actuator, where the anchor is made of ferromagnetic material.
