Abstract (en)

The regulator has at least one connecting rod (8) acting on the valve shaft (16) of the gas exchange valve, linked to an armature which is reciprocated between the pole faces (5,6) of a pair of axially spaced electromagnets (1,2). The armature is held in an intermediate position between the pole faces when the electromagnets are not energised by a pair of opposing spring elements (12,19), positioned on the outside of the electromagnets.

Abstract (de)

Die Erfindung betrifft eine elektromagnetische Stellvorrichtung zur Betätigung eines Gaswechselventils an einer Brennkraftmaschine, die eine Schubstange (8) aufweist, die auf das zu betätigende Gaswechselventil (15) einwirkt und die mit einem Anker (7) verbunden ist, der zwischen den Polflächen (5, 6) von zwei in axialem Abstand zueinander angeordneten Elektromagneten (1, 2) hin und her bewegbar geführt ist und der bei stromlos gesetzten Elektromagneten (1, 2) durch wenigstens zwei gegeneinander wirkende Federelemente (12, 19) in einer Zwischenstellung zwischen den Polflächen (5, 6) gehalten wird, und wobei die beiden gegeneinander wirkenden Federelemente (12, 19) außerhalb der Elektromagneten (1, 2) auf der dem Gaswechselventil (15) zugekehrten Stirnseite des Elektromagneten (2) angeordnet sind, wobei ein erstes Federelement (19) auf einen Ansatz (18) am Gaswechselventil (15) in Schließrichtung einwirkt und wobei ein zweites Federelement (15) auf die Schubstange (8) in Öffnungsrichtung einwirkt und die Schubstange (8) und der Ansatz (18) kraftschlüssig miteinander verbunden sind. <IMAGE>
