 nur in die Bohrung   40   eingesetzt worden, da er bei der ersten Rückwiirtabcwegung des Kolbens durch das in der Bohrung   40   eingeschlossene Druckmittel fest auf den   konischen Ansatz ? 9 mu   unteren Ende der Stange aufgedrückt wird. 



   PATENT-ANSPRÜCHE : 
1. Vorrichtung an mit einem elastischen Druckmittel betriebenen Kraftwerkzeugen zum elastischen Auffangen des Stosskolbens, dadurch gekennzeichnet, dass der Stosskolben mit einer Bohrung oder dgl. versehen ist, in die beim Arbeitshub des Stosskolbens das Druckmittel eintreten kann, das beim   Rückwärtshub   des Stosskolbens infolge des Absperrens der Einlassöffnung zu der   Bohrung von dem Stosskolben verdichtet wird, wodurch letzterer am Ende seines Rückwärtshubes elastisch aufgefangen wird.

 EMI3.1
 has only been inserted into the bore 40, since during the first return movement of the piston by the pressure medium enclosed in the bore 40, it is firmly on the conical extension? 9 must be pressed on the lower end of the rod.



   PATENT CLAIMS:
1. A device on power tools operated with an elastic pressure medium for elastically catching the ram, characterized in that the ram is provided with a bore or the like, into which the pressure medium can enter during the working stroke of the ram that occurs during the backward stroke of the ram as a result of locking the inlet opening to the bore is compressed by the push piston, whereby the latter is elastically absorbed at the end of its backward stroke.

Claims (1)

2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass in die Bohrung des Stoss- EMI3.2 sitzt, der beim Arbeitshub des Stosskolbens einen Teil des denselben vortreibenden Druckmittels in die Bohrung des Stosskolbens eintreten lässt und darin einschliesst, so dass beim Rückwärtshub des Stosskolbens das in seiner Bohrung eingeschlossene Druckmittel gegen den in der Bohrung sitzenden Kolben (20) verdichtet wird. EMI3.3 schlossen wird, wodurch das in die Bohrung dem Stosskolbens eingetretene Druc mittel in der Bohrung festgehalten wird. 2. Device according to claim 1, characterized in that in the bore of the shock EMI3.2 sits, which during the working stroke of the ram allows part of the same propulsive pressure medium to enter the bore of the ram and lock it in, so that during the backward stroke of the ram, the pressure medium enclosed in its bore is compressed against the piston (20) seated in the bore. EMI3.3 is closed, whereby the entered into the bore of the piston pressure medium is held in the bore. 4. Vorrichtung nach Anspruch 1 bis 3, dadurch gekennzeichnet, dass in dem in die Bohrung eingepassten, das Druckmittel in der Bohrung einschliessenden Kolben (20) ein Rückschlagventil (21) angeordnet ist, das von dem beim Arbeitshub des Stosskolbens einströmenden Druck- EMI3.4 4. Apparatus according to claim 1 to 3, characterized in that a check valve (21) is arranged in the piston (20) which is fitted into the bore and encloses the pressure medium in the bore, which is controlled by the pressure flowing in during the working stroke of the ram piston EMI3.4
