ABSTRACT:
A control system for a dental handpiece, and the like, for supplying a pressurized drive fluid, pressurized air, and water to the handpiece, and which includes a holder for the handpiece having an internal pinch valve which is operated whenever the handpiece is inserted or removed from the holder. A control module is provided which actually controls the flow of the various fluids to the handpiece. The control module includes a pinch lever which engages the various tubes carrying the fluids to the handpiece, and it also includes a swell tube which responds to pressurized fluid from the handpiece holder whenever the handpiece is removed. A linkage system couples the swell tube to the pinching lever in the control module. A feature of the control system is that a pressurized fluid of relatively low pressure is controlled by the insertion and removal of the handpiece from the holder, and it acts as a pilot to cause the control module to exert sufficient force on the various tubes carrying the fluids to the handpiece so as to achieve a positive control over the flow of the fluids.
