  Durch Druckmittel betriebenes Schlagwerkzeug. 
 EMI1.1 
 des als Stufenkolben ausgebildeten Schlagkolbens wirkt und ein Kanal zur Zuleitung des Kraftmittels für den Rückhub vom Kolben selbst nahe dem Ende seines Vorwärtshubes geöffnet wird. 



   Die Erfindung bezweckt die Dauer, während welcher dieser Kanal geöffnet ist, in der Weise zu verlängern, dass der Zulass des Kraftmittels nach dem vorderen Zylinderende erst beginnt, wenn der Kolben praktisch das Ende seines Vorwärtshubes erreicht hat, jedoch während eines hinlänglichen Teiles seines Rückhubes noch anhält, um so einen vollen Rückhub zu erhalten. Hiedurch wird ein stärkerer Schlag des Kolbens ohne Mehrverbrauch an Kraftmittel erzielt. 



   Zu diesem Zweck besitzt der Überleitungskanal hinter der vom Kolben gesteuerten Einlass-   önnung   noch eine zweite Einlassöffnung, die gleichfalls von dem Raume des Zylinders hinter dem Kolben ausgeht und von   einem   Hilfssteuerschieber gesteuert wird. 
 EMI1.2 
 praktisch am Ende seines Schlaghubes angelangt ist. 



   Die   Öffnung 77   führt direkt   in   den   Kanal 9. wahrend xum Steuern   der Öffnung 10 ein besonderer Schieber 12 vorgesehen ist. Dieser Schieber 12 gleitet in einem Schieberkasten 13

  Impact tool operated by pressure medium.
 EMI1.1
 of the percussion piston designed as a stepped piston acts and a channel for supplying the power means for the return stroke is opened by the piston itself near the end of its forward stroke.



   The invention aims to extend the duration during which this channel is open in such a way that the admission of the fuel to the front end of the cylinder does not begin until the piston has practically reached the end of its forward stroke, but still during a sufficient part of its return stroke stops to get a full return stroke. This results in a stronger stroke of the piston without consuming more fuel.



   For this purpose, the transfer channel behind the inlet opening controlled by the piston has a second inlet opening, which also starts from the space of the cylinder behind the piston and is controlled by an auxiliary control slide.
 EMI1.2
 has practically reached the end of its stroke.



   The opening 77 leads directly into the channel 9, while a special slide 12 is provided to control the opening 10. This slide 12 slides in a slide box 13
