Gear for operating of gas exchange valve in internal combustion engine has rotational angle sensor connected to pivot anchor and which in at least one operating state records pivot anchor's rotational angle

The gear for the operating of a gas exchange valve (2) in an internal combustion engine has a rotational angle sensor (60) connected to a pivot anchor (20) and which in at least one operating state records the rotational angle of the pivot anchor. The rotational angle sensor comprises a sensor element and a measuring element, whereby the measuring element is movably mounted in relation to the sensor element. The sensor element is rigidly connected to a housing (46) which at least partially encloses the pivot anchor. Die Erfindung geht aus von einer Vorrichtung zur Betätigung eines Gaswechselventils einer Brennkraftmaschine mit einem um eine Drehachse drehbar gelagerten Schwenkanker. DOLLAR A Es wird vorgeschlagen, dass der Schwenkanker mit einem Drehwinkelsensor verbunden ist, der in zumindest einem Betriebszustand der Brennkraftmaschine einen Drehwinkel des Schwenkankers erfasst.
