    Abstract: 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).

    Abstract: A novel turbine motor spindle assembly for a spindle-mounted pneumatic tool, especially in a live tool environment is described. The novel turbine motor spindle assembly includes a manifold with a front end and a rear end. The manifold includes an air intake passage for receiving pressurized air. The pressurized air is directed axially through a drive shaft rotatably coupled to the front end. The pressurized air drives a turbine motor assembly and a drive shaft. The drive shaft is mounted inside a housing with self-lubricating. The turbine motor assembly includes tangential openings for expelling exhaust air therefrom. The turbine motor housing is mechanically coupled to the front end of the manifold with an exhaust air passage for directing exhaust air from the one or more tangential openings out through the rear end of the manifold. The combined overall length of the turbine motor spindle assembly is no more than 1.76 inches in length for live tooling applications.

    Abstract: In an improved air inlet valve assembly, a flow of air along a first or second flow path may be controlled by a position of air inlet guide surfaces of a rotatable valve relative to air inlet guide slots of a fixed valve sleeve. Air flowing along the first flow path may rotate a motor in a first direction to operate the tool in a forward mode. Air flowing along the second flow path may rotate the motor in the second direction to operate the tool in a reverse mode. In the forward mode, as air flows along the first flow path, air may be discharged along a primary discharge path, with a portion of the second flow path providing a secondary discharge path. In the reverse mode, as air flows along the second flow path, air may be discharged along the primary discharge path, with a portion of the first flow path providing the secondary discharge path.

    Abstract: A turbine power unit for a power tool having a turbine housing with an interior space configured to receive therein a fluid powered turbine supported for rotation on a bearing within the turbine housing. A service opening through the turbine housing into the interior space thereof, the service opening configured to permit installation and removal of a bearing into and out of the interior space of the turbine housing. A removable cover releasably securable to the turbine housing over the service opening and transitionable between an open configuration in which a bearing can be installed into and removed from the interior space of the turbine housing through the service opening and a closed configuration in which an installed bearing within the interior space is secured for operation in the turbine housing.

    Abstract: In a pneumatic-powered tool, a flow of air along a first or second flow path may be controlled by a position of air inlet guide surfaces of a rotatable valve relative to air inlet guide slots of a fixed valve sleeve. Air flowing along the first flow path may rotate a motor in a first direction to operate the tool in a forward mode. Air flowing along the second flow path may rotate the motor in the second direction to operate the tool in a reverse mode. In the forward mode, as air flows along the first flow path, air may be discharged along a primary discharge path, with a portion of the second flow path providing a secondary discharge path. In the reverse mode, as air flows along the second flow path, air may be discharged along the primary discharge path, with a portion of the first flow path providing the secondary discharge path.
