Abstract:
A hand-held pneumatic rotary drive device comprising:a generally elongate housing sized and shaped to be held in the hand having a forward end and a rearward end as so held and having an axis extending longitudinally endwise thereof;said housing having a chamber adjacent its forward end and a pneumatic motor having a rotor rotary in said chamber on said axis;a drive shaft driven by said rotor extending out of said forward end of the housing;said housing having an inlet passage for pressurized air at said rearward end thereof extending in generally longitudinal direction relative to said housing;an air hose connector rotary in sealed relation to said housing on an axis extending in generally longitudinal direction relative to said housing, said connector being of tubular form having a bore for flow of pressurized air to said inlet passage, said connector being for connection of an air hose for supplying pressurized air from a source thereof to the bore of said connector and allowing swivelling of the housing relative to the hose and connector;said housing having air delivery passaging for flow of pressurized air from said inlet passage to the motor;said delivery passaging having a valve therein;said housing having a member thereon operable by the hand holding the device for operating the valve;said housing having air exhaust passaging therein for exhausting air from the motor chamber extending from the chamber to an outlet at said rearward end of the housing laterally outward of said connector; andan air deflector for exhaust air exiting said exhaust passaging outlet rotatable around said connector for deflecting exhaust air laterally outward in a selected direction away from the user holding the device.
