ABSTRACT:
A dental compressed-air motor, consisting of a housing in which there is arranged a rotatably supported rotor adapted to be set into rotation by means of operational compressed air which is introduced into the housing through the intermediary of an operational compressed-air inlet conduit, and which includes a rotor shaft connectable with a work tool, wherein the operational compressed-air inlet conduit has associated therewith a regulating device located within the housing, with an externally operable handle for effecting the turning of a rotary slide valve supported within the motor housing for variation of the rotational speed and/or the direction of rotation of the rotor. Furthermore, at one end of the motor housing there are provided coupling means for connection with a dental handpiece supporting the work tool and, at the other end of the motor housing, coupling means in the form of an attachment element for connection with a supply hose conducting compressed air or other media streaming towards or from the motor housing or handpiece, whereby the rotary slide valve is located intermediate the motor and the attachment element and whereby the attachment element is provided with essentially axially incoming and essentially axially further extending media through-passageways which are connected to the media conduits leading to the location of application for the compressed-air motor or the handpiece.
