Abstract

Die Erfindung betrifft eine Schutzvorrichtung an einem fluidbetriebenen Schlagwerk, mit einem in einem Gehäuse (2) beweglich geführten Schlagwerkzeug (3) - das mittels eines Schlagkolbens in Schlagrichtung (Pfeil 1) angetrieben wird - und mit einer Dichtung (7), die sich zumindest mittelbar einerseits an dem Gehäuse (2) und andererseits an dem Schlagwerkzeug (3) abstützt und deren Befestigungsabschnitt (7a) entweder bezüglich des Gehäuses oder des Schlagwerkzeugs ortsfest angeordnet ist.
Mit der Erfindung wird der Vorschlag unterbreitet, eine gattungsgemäße Schutzvorrichtung derart auszubilden, daß die Dichtung (7) zwischen dem - in Gegenrichtung zur Schlagrichtung (Pfeil 1) gesehen - inneren Führungsabschnitt (5b) der Schlagwerkzeug-Führung und der theoretischen Aufschlagebene (4) des Schlagkolbens auf das Schlagwerkzeug (3) derart angeordnet ist, daß die relativ zum Befestigungsabschnitt (7a) der Dichtung (7) bewegliche, mit dieser in Kontakt stehende Gegenfläche (3e) verschleißfrei ist.
