Abstract (en)

[origin: DE4003229A1] In prior art electromagnetically operated valves with a core surrounded by a coil magnet and with an armature by means of which a valve-closure element operating in conjunction with a rigidly mounted valve seat is actuated, the periphery of the coil magnet is surrounded by at least one U-shaped conduction element which orients the magnetic-field lines. This gives rise to undesirable stray flux, however. The new valve is at least partly surrounded by a metal housing (3) which completes the magnetic circuit and is hermetically joined at the upper end (35) to the core (1) and at the lower end (36) to a connector piece (8) and projects at least in the longitudinal direction beyond the coil magnet (2). This valve design is particularly suitable for use as an injection valve in a fuel-injection system.
