ABSTRACT:
The device forms part of an automatic control facility by which the water-primed oral suction pump in dental surgery equipment is protected from the effects of low water pressure and power cuts; the efficiency of control is improved by the inclusion of timers (7, 9) that ensure continued operation of the pump and its inlet valve in the event that fluctuations in the water pressure and electrical power levels happen to be of a momentary order.
