Patent ID: 8333253

Claim:
An outlet deflector unit for a pneumatic power tool with a housing having an air outlet passage with an outlet opening, the outlet deflector unit comprising: a retaining socket having a collar; a cup-shaped deflector element that is rotatably supported around an axial axis of the housing and axially sandwiched between a rear end of the housing and the collar of the retaining socket such that said deflector element is fixed in place and not translatable in a direction along said axial axis, said deflector element communicating with the outlet opening and having an axially directed curved banana-shaped opening and one radially directed opening, wherein said radially directed opening extends along a certain angular interval around a circumference of the deflector element, and wherein said axial axis extends in a longitudinal direction of the housing through a geometric center thereof; and a cup-shaped sector element arranged inside the deflector element and rotationally locked relative to the housing, said sector element having one radially directed side slot extending along a certain angular sector which is larger than said certain angular interval for said radially directed opening of the deflector element, and an axially directed curved banana-shaped outlet port extending over a second angular interval not covered by said certain angular sector and having substantially a same size as said axially directed curved banana-shaped opening of the deflector element, wherein said deflector element is rotatable to accomplish alignment either between said radially directed opening and said side slot of the sector element, or between said axially directed curved banana-shaped opening and the axially directed curved banana-shaped outlet port of the sector element, and wherein said certain angular sector extends over an angular interval substantially larger than the certain angular interval for the radially directed opening, thereby enabling a variation of a radial outlet flow direction within said certain angular interval without uncovering the axially directed curved banana-shaped outlet port.
