摘要：An improved air intake and exhaust device for a pistol type air impact wrench which does not discharge its exhaust air into the atmosphere directly from the end of its handle, but discharges it into the atmosphere at a considerable distance from the end of its handle to prevent any dust, etc. from rising at the site of work and any noise from being produced and thereby improve the working environment. In an air in-take and exhaust device for a pistol type air impact wrench having at the end of its handle an intake port and an exhaust port for compressed air for operating an air motor, a silencing bellows tube surrounding an air intake tube connected to the intake port is attached to the end of the handle and the silencing bellows tube and the air intake tube define an annular passage therebetween as an air exhaust passage.
