Title
(DE) SCHLAGWERKVORRICHTUNG
(EN) PERCUSSION MECHANISM APPARATUS
(FR) DISPOSITIF À PERCUSSION
Abstract
(DE)
Die Erfindung geht aus von einer Schlagwerkvorrichtung, insbesondere für einen Bohr- und/oder Meisselhammer, mit zumindest einem Schläger (12), mit zumindest einem Schlagbolzen (14), der zumindest eine dem Schläger (12) zugewandte Führungsnase (16) aufweist, und mit zumindest einer beweglich gelagerten Steuerscheibe (18), die um die Führungsnase (16) angeordnet ist. Es wird vorgeschlagen, dass ein Ende (20) der Führungsnase (16) in jedem Betriebszustand über die Steuerscheibe (18) hinausragt.
(EN)
The invention proceeds from a percussion mechanism apparatus, in particular for a rotary and/or demolition hammer, having at least one striker (12), having at least one percussion pin (14) which has at least one guide lug (16) facing the striker (12), and having at least one movably mounted control disc (18) which is arranged around the guide lug (16). It is proposed that one end (20) of the guide lug (16) projects beyond the control disc (18) in every operating state.
(FR)
L'invention concerne un dispositif à percussion, en particulier pour marteau perforateur et/ou marteau-burineur, qui comprend au moins un marteau (12), au moins un percuteur (14) qui présente au moins un ergot de guidage (16) tourné vers le marteau (12), ainsi qu'au moins un plateau de commande(18) monté mobile qui est disposé autour de l'ergot de guidage (16). Selon l'invention, il est prévu qu'une extrémité (20) de l'ergot de guidage (16) fasse saillie du plateau de commande (18) dans chaque état de fonctionnement.
