Description
Claims (3)
mit einem von einer Tragkonstruktion gehaltenen Motor (26) mit einem sich im Motorgehäuse (72) drehenden Abtriebselement (66),
mit einem Kolbenantriebselement (40) zum Betätigen des Kolbens (16), das einen von dem Abtriebselement (66) des Motors (26) über ein Gewinde (44) angetriebenen Teil und einen sich aufgrund der Drehung zwischen dem Abtriebselement (66) des Motors (26) und dem angetriebenen Teil axial verschiebenden Teil hat, und
mit einer Vorrichtung zum Abschalten des Motors beim Auftreten eines Widerstandes gegen die axiale Bewegung des Kolbenantriebselementes (40), die an der Tragkonstruktion widerstandsabhängig gelagert ist und die den Motor über einen Fühler bei Überschreiten eines vorgegebenen Widerstandswertes abschaltet,
dadurch gekennzeichnet, daß die Vorrichtung zum Abschalten des Motors (26) ein gegenüber der Tragkonstruktion drehbares Motorgehäuse (72) umfaßt, das mit der Tragkonstruktion über einen Drehmomentwiderstand verbunden ist, der eine Drehung zwischen der Tragkonstruktion und dem Motorgehäuse (72) nur dann zuläßt, wenn das zwischen diesen auftretende Drehmoment einen vorbestimmten Wert überschreitet, und daß der Fühler zum Abschalten des Motors (26) in einem Drehfühler besteht, der beim Auftreten des Widerstandes gegen die axiale Bewegung des Kolbenantriebselements (40) eine Drehung des Motorgehäuses (72) gegenüber der Tragkonstruktion feststellt.
