Abstract
The invention relates to a compressed air motor comprising a housing and a rotor rotatably mounted therein, the rotor being provided with substantially radial slots and plate-like vanes being mounted in the slots so as to be radially displaceable by the centrifugal force, and variable, all-round air chambers being formed between the housing and the outside of the rotor. The vanes are surrounded on the outside by a rotatable sleeve which is provided with at least one passage for the compressed air.
Claims13
A compressed air motor, comprising:
- a housing having a guide bore;
- a rotor rotatably mounted in the guide bore, the rotor having:
- (i) slots running in an outward direction, and (ii) plate-like vanes mounted on the rotor so as to be displaceable outwards by a centrifugal force;
- and
- a freely rotatable sleeve arranged in a region between an outside of the rotor and the guide bore of the housing, wherein the rotatable sleeve has at least one passage in a lateral surface thereof for compressed air and at least one of the rotatable sleeve and the vanes consist of plastic, wherein at least one of the rotatable sleeve and the vanes comprise phenol resin and a fine cotton fabric.
