Abstract (en)

A sliding switch (36) encloses the rear section (21) of the rotary device casing (16) in the compressed air supply channel region, and is provided with axial guide pins (41) secured to a brake disc (44) in the braking device (14) cooperating with the switch. Pressurised fluid can flow into the turbine part of a rotor (12) in the front section (17) of the rotary device casing. A sliding switch for the pressurised fluid supply cooperates with a braking device.

Abstract (de)

Eine Druckfluid betriebene Drehvorrichtung (11) für Druckluftwerkzeuge (10) ist mit einem Gehäuse (16) und einem in einem vorderen Gehäuseteil (17) rotierbar angeordneten Rotor (12), in dessen Turbinenteil das unter Druck stehende Fluid strömen kann, mit einer Bremseinrichtung (14) und mit einem mit der Bremseinrichtung (14) in Wirkverbindung stehenden Schalter (36) für das Druckfluid, der an einem hinteren Gehäuseteil (21) im Zuge eines Druckfluid-Zuführkanals (26) angeordnet ist, versehen. Damit eine derartige Drehvorrichtung (11) mit weniger Bauteilen auskommt und in einfacherer und schnellerer Weise über einen Fluidschalter (36) zum Stillstand gebracht werden kann, ist ein das hintere Gehäuseteil (21) im Bereich des Zuführkanals (26) umgebender Schiebeschalter (36) vorgesehen, der mit axial gerichteten Steuerstiften (41) versehen ist, die mit einer Bremsscheibe (44) der Bremseinrichtung (14) verschiebefest verbunden sind. <IMAGE>
