摘要： A pneumatic power tool comprises a housing (10), a motor, a pressure air inlet passage (11,15), an exhaust air outlet passage (12,17), and an exhaust air outlet flow deflector (14) including an outlet piece (20) with radial as well as axial outlet openings (25, 26) and a valve element (21) with radial as well as axial apertures (30, 28), wherein the outlet piece (20) and the valve element (21) are rotatable relative to the housing (10) as well as to each other to bring alternatively a radial opening (25) of the outlet piece (20) into or out of alignment with a radial aperture (30) of the valve element (21), and at the same time bring the axial apertures (28) of the valve element (21) out of or into alignment with the openings (26) of the outlet piece (20), thereby shifting the exhaust outlet flow direction as desired between a radial direction and an axial direction.

摘要： A pneumatic power tool comprises a housing (10, 11) with a motor and a pressure air inlet passage (12) and an exhaust air outlet passage (16) both extending through the housing (10, 11) and communicating with the motor, wherein the outlet passage (16) is provided with sound attenuating elements (36, 37) formed in a highly porous resinous material and arranged to be penetrated by the exhaust flow for exhaust noise reduction, and an exhaust flow diverting deflector (17) mounted at the outlet end of the outlet passage (16) and comprising a shell like body (18) with a cylindrical neck portion (19) rotatively received in the outlet passage (16), a concave flow guiding surface (28), and two parallel inner walls (30a,b) forming between them a main flow passage (31) and between them and the shell body (18) two narrow secondary flow passages (32a,b) for accomplishing noise dampening low velocity air flow shields on both sides of the main flow.
