An arrangement for compressed-air driven hand tools and other compressed-air apparatus fitted with handles of the kind wherein a handle 1 has a flow passage 4 for removing air which has expanded in the apparatus and is therefore cold. The handle has a body 5 which serves directly as a hand grip, or is fitted with some form of grip-transfer device such as a grip casing. A partition is arranged in the handle body between the flow passage for the expanded air and the handle body in order to form an air passage 19 between itself and the body. This passage has an inlet 20 connected to the duct system 6 of the apparatus for supplying compressed air, and an outlet 21 which is so situated that the passage into an area which is enclosed by the handle body's grip zone is traversed by a flow of compressed air which expands soonest in the air-passage outlet, whereby this flow prevents the cooling-down of the handle which would be uncomfortable for the user. <IMAGE> |
