Electromagnetically operated valve, particularly fuel injecting valve for fuel injection systems, has valve longitudinal axis and excitable actuator in form of electromagnetic circle with magnetic coil

摘要

The electromagnetically operated valve has a valve longitudinal axis (10) and an excitable actuator in form of an electromagnetic circle with a magnetic coil (1), a fixed core (2) and a movable anchor for actuating a valve closing body (19). The valve closing body is worked together with a valve face (16) provided at a valve seating body (15) and has a plastic extrusion coat (46), which surrounds the magnetic coil. Multiple elongated metallic threads (5) are embedded in the plastic extrusion coat. The metallic threads are manufactured from a ferromagnetic material.
