Patent ID: 7398836

Claim:
A pneumatic power tool, comprising a housing, a motor, a pressure air inlet passage and an exhaust air outlet passage, and an adjustable exhaust air outlet deflector rotatably supported on said housing wherein said outlet deflector comprises: a cup-shaped outlet piece having at least one radially directed outlet opening, and at least one axially directed outlet opening arranged in a certain pattern; and a valve element which is rotatably supported in a co-axial relationship with said outlet piece, and which has at least one axially directed aperture arranged in a pattern congruent with said certain pattern of said at least one axially directed outlet opening of said outlet piece, and at least one radially directed aperture to be selectively brought into alignment with said at least one radially directed outlet opening of said outlet piece; wherein said outlet piece and said valve element are rotatable relative to each other between: a first relative position at which said at least one axially directed aperture of said valve element coincides fully with said at least one axially directed outlet opening of said outlet piece, and at which said at least one radially directed aperture of said valve element does not at all coincide with said at least one radially directed outlet opening of said outlet piece, such that the outlet deflector directs outlet flow of exhaust air axially through the coinciding at least one axially directed aperture and at least one axially directed outlet opening; and a second relative position at which said at least one radially directed aperture of said valve element coincides fully with said at least one radially directed outlet opening of said outlet piece, and at which said at least one axially directed aperture of said valve element does not at all coincide with said at least one axially directed outlet opening of said outlet piece, such that the outlet deflector directs the outlet flow of the exhaust air radially through the coinciding at least one radially directed aperture and at least one radially directed outlet opening.
