ABSTRACT:
This air-water mixer for the atomizer of a dental hand piece comprises a body formed with a circular chamber into which open an air supply conduit, a water supply conduit and an outlet conduit for the fluids. One wall of this chamber consists of the inner face of a selector ring mounted for free rotation in the chamber, the inner face of the ring comprising a flat sector adapted to close the inlet port of one and/or the other supply conduits in predetermined positions of the ring, and an inclined sector permitting the free passage of fluid between one and/or the other of the supply conduits and the outlet conduit in other predetermined positions of the ring, this mixer being particularly suited for a dental hand piece provided with an air-water atomizing conduit.
