Title
(EN) Hand-held pneumatic rotary drive device having adjustable air exhaust
(ZH) 带有可调排气装置的手持气动旋转驱动装置
Abstract
(EN) A hand-held pneumatic rotary drive tool 1 having an adjustable exhaust 31. The tool 1 has an elongate housing 3 containing a pneumatic motor M. The housing 3 has an inlet passage 15 for pressurized air at the rearward end 7 of the housing and air delivery passaging 21 for flow of pressurized air to the motor M. A rotary connector 17 on the housing at the inlet passage 15 permits connection to an air hose. The housing 3 also has an air exhaust passage 27 for exhausting air from the motor M. An air deflector 31 for exhausting air exiting the exhaust passage 27 is rotatable around the connector 17 for deflecting exhaust air laterally outward in a selected direction away from a user holding the tool. The annulus wall 143 of the deflector 31 has an opening 151 for exhausting the deflecting air.
(ZH)

一种手持气动旋转驱动工具(1),其带有一个可调节的出口(31),该工具(1)有一个伸长的壳体(3),其包括一个气动马达(M)。该壳体(3)在其后端(7)有一个用于压缩气体的进口通道(15)以及一个使压缩气体流到马达(M)输送通道(21)。在壳体上进口通道(15)的一个旋转连接件(17)能连接一根空气软管。所述壳体(3)还有一个用于来自马达(M)的排放气体的气体排放通道(27)。一个用于从排放通道(27)排出气体的气体导向件(31)可旋转地围绕连接件(17),以便远离握持装置的使用者沿选定的方向横向地导出排放气体,导向件(31)的环形壁(143)有一个开口(151),用于导向气体的排放。
