ABSTRACT:
A pneumatic vane motor comprising a cylinder and a vane carrying rotor. The vanes are reciprocably guided in radial slots in the rotor, which slots have a width exceeding the thickness of the vanes. For preventing the vanes from seating flatly on the slot walls they are provided with projection protruding from their both faces at a distance from their inner edges. Thereby, the projections are protected from wear as the vanes, during load transmission to the rotor, reciprocate in the slots.
