Abstract
A turning device for compressed air tools. which is operated by a compressed fluid, is provided with a housing and with a rotor, which is rotatably arranged in a front housing part and into whose turbine element the fluid, which is under pressure, can flow, has a braking arrangement and a switch for the compressed fluid. The switch which is operatively connected with the braking arrangement and is arranged on a rear housing part in line with a compressed fluid supply conduit. Such a turning device requires fewer components and can be stopped in a simpler and faster way by a fluid switch, in the form of a sliding switch, which encloses the rear housing part in the area of the supply conduit and is provided with axially oriented control pins, which are connected, fixed against relative displacement, with a brake disk of the braking arrangement.
