Abstract

Ein rahmenartiges Gehäuse (1) eines elektromagnetischen Aktuators (2) zur Ventilbetätigung, insbesondere in Brennkraftmaschinen, umfaßt in über Schenkel (3) beabstandeten Quertraversen (4) fluchtend angeordnete Führungseinrichtungen (6,7) für einen einteiligen Stößel (11) mit einem hubgesteuerten Anker (10), wobei die Schenkel (3) des Gehäuses (1) mittels Bruchtrennen (13) im Bereich des Ankers (10) geteilt sind.

Figure 00000001
A frame-like housing (1) of an electromagnetic actuator (2) for valve actuation, in particular in internal combustion engines, comprises guide devices (6, 7) for a one-piece tappet (11) with a stroke-controlled armature, which are arranged in alignment with cross members (4) spaced apart by legs (3) (10), the legs (3) of the housing (1) being broken by means of fracture separators (13) in the region of the armature (10).
