Abstract

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.

The invention relates to an electromagnetic actuating device for actuating a gas exchange valve on an internal combustion engine, which has a push rod (8) which acts on the gas exchange valve (15) to be actuated and which is connected to an armature (7) which is connected between the pole faces (5, 6) is guided to move back and forth by two electromagnets (1, 2) which are arranged at an axial distance from one another and which, when the electromagnets (1, 2) are de-energized, by means of at least two spring elements (12, 19) acting in opposite directions in an intermediate position between the pole faces ( 5, 6), and the two spring elements (12, 19) acting against each other are arranged outside the electromagnets (1, 2) on the front side of the electromagnet (2) facing the gas exchange valve (15), a first spring element (19 ) acts on a shoulder (18) on the gas exchange valve (15) in the closing direction and a second spring element (15) on the push rod (8) in the opening direction acts and the push rod (8) and the approach (18) are non-positively connected.
