ABSTRACT:
A pneumatic power tool includes a housing, a motor, a pressure air inlet passage, an exhaust air outlet passage, and an exhaust air outlet flow deflector. The exhaust air outlet flow detector includes an outlet piece with radial as well as axial outlet openings and a valve element with radial as well as axial apertures. The outlet piece and the valve element are rotatable relative to the housing as well as to each other to bring a radial opening of the outlet piece into or out of alignment with a radial aperture of the valve element (21), and at the same time to bring the axial apertures of the valve element out of or into alignment with the openings of the outlet piece, thereby shifting the exhaust outlet flow direction as desired between a radial direction and an axial direction.
