摘要： The invention refers to a pneumatically driven apparatus, in particular a hand guided and/or hand held pneumatic power tool (1), comprising a pneumatic rotary vane motor (100), a working element (9) and a gear arrangement functionally located between the motor (100) and the working element (9) for transmitting a rotational movement and torque. The motor (100) comprises a housing defining a cylindrical chamber (114) extending along a cylinder axis, and a cylindrical rotor (104) located in the chamber (114) and extending along and rotatable about an axis (60) running parallel to the cylinder axis, the rotor (104) comprising a plurality of radially movable vanes (108) forced radially outwards during rotation of the rotor (104). It is suggested that the gear arrangement is a magnetic gear arrangement (20) and that the rotor (104) of the motor (100) comprises permanent magnets (56) attached thereto between the vanes (108) thereby making the rotor (104) of the pneumatic motor (100) form one of the rotating components (52; 54) of the magnetic gear arrangement (20).
