Title
(DE) HANDGEHALTENE PNEUMATISCHE DREHANTRIEBSVORRICHTUNG MIT EINEM REGELBAREN LUFTABZUG
(EN) HAND-HELD PNEUMATIC ROTARY DRIVE DEVICE HAVING AN ADJUSTABLE AIR EXHAUST
(FR) OUTIL PNEUMATIQUE D'ENTRAINEMENT EN ROTATION AYANT UN SYSTEME D'ECHAPPEMENT D'AIR AJUSTABLE
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 (3) 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 annular wall (143) of the deflector (31) having an opening (151) for directional later exhaust.
