Air vane motors consist of a housing with a cylindrical bore and the rotor with the vanes.
The vanes divide the crescent-shaped working chamber into several pressure chambers.
The incoming compressed air causes the eccentrically mounted motor shaft to rotate over vanes that are always displaced toward the housing wall in radial slots in the rotor.
The pressure chambers enlarge during rotation, therefore the compressed air relaxes and flows through the outlet into the open air.
The torque delivered to the motor shaft depends on the pressure of the air and the area of the vanes that is pressurized.
Air motors for one direction of rotation have only one compressed air connection and are identified by a corresponding circuit symbol.
Air motors for clockwise and counterclockwise rotation are identified by circuit symbols and have two compressed air connections which are selectively pressurized via a valve.
