Abstract
An improved percussor assembly comprises a rigid body member having gas inlet and gas outlet means, the latter including a restricted passageway and an enlarged passageway, and a vent passageway communicating with the enlarged portion adjacent the junction of the restricted passageway whereby atmospheric air is entrained into the enlarged passageway as gas flows therein from the restricted passageway thereby increasing the volume of gas supplied to a remote applicator while economizing on the amount of pressurized gas required to operate the percussor. The vent passageway also relieves gas pressure from a remote pneumatic applicator between successive bursts of gas from the percussor assembly. An improved remote applicator having means for selecting the force of the percussive bursts is also provided.
