Abstract
A compressed air supply system for vibro-isolated tools comprises a telescopic-tubular connection between the tool grip and the tool compressed air engine. A cut-off valve is mounted at the inlet to a supply duct through the grip, the outlet of the duct being connected to a pipe of the supply system mounted in the grip by means of an elastic connection. The pipe of the supply system has holes through the wall thereof with increasing diameters which, during motion of the tool housing relative to the compressed air engine, overlap with holes in an intermediate sleeve into which the air supply pipe slidably extends. The intermediate sleeve conveys the air to the air engine.
