Patent ID: 8015997

Claim:
An apparatus comprising: an elongated tool housing having a longitudinal axis, axially front and rear ends, and a surface extending circumferentially about the longitudinal axis; an output structure exposed through the front end of the housing and rotatable about the longitudinal axis; and a bi-directional air motor having first and second inlets through which air can be directed to power the motor to drive the output structure in respectively forward and rearward directions; a valve body supported by the housing, having an inlet port and first and second outlet ports respectively connected to the first and second motor inlets; and a valve stem extending, in the valve body, along a transverse axis that is perpendicular to the longitudinal axis of the housing, the stem being linearly shiftable between a first activating position that causes the air to be discharged from the first outlet port but not the second outlet port, a second activating position that causes the air to be discharged from the second outlet port but not the first outlet port, and a neutral position, located between the two activating positions, that does not cause the air to be discharged from either outlet port; a sleeve that is received about the valve body and extends circumferentially about the transverse axis and overlies the inlet port and is rotatable about the transverse axis relative the body; and a nozzle projecting radially outward from the sleeve and rotatable with the sleeve into a range of positions in which the nozzle communicates with the inlet port through the sleeve.
