ABSTRACT:
A percussor assembly comprises a rigid body member having a gas inlet passageway and gas outlet passageway, a movable gas sealing member, and a gas pressure chamber communicating with the gas inlet passageway, the gas sealing member being forced from a first position forming a gas-tight seal between the gas pressure chamber and the gas outlet passageway to a second position in which the chamber and passageway are in communication to allow a burst of gas to pass from the chamber into the outlet passageway. A percussion head, which may be remote from the body member receives the burst of gas, the bursts being created successively at the percussion head.
