ABSTRACT:
The air-driven vibrator (10) includes a disc-shaped vibratory element (40) movably received in a disc-shaped working chamber (38). Upon injecting air jets into the chamber (38) through tangential injection ports (46), the element (40) is rotated and oscillated to generate vibration. The feature of the vibrator is that inwardly directed projections (66, 72) are provided on the inner end faces (34, 36) of the chamber (38) to prevent the element (40) from sticking to the end faces (34,36) when the vibrator is not in use. Due to the provision for the projections (66, 72), the edge of the element (40) need not be chamfered. This enables mass production of the elements (40) and increases the production yield of the elements (40).
