Abstract
A dental air-water handpiece control system for operating a plurality of handpieces and an air-water syringe including a plurality of control pedals equal in number to the number of handpieces and each having a needle valve responding to the distance the pedal moves when operated. Replaceable control modules are also included, with each module servicing a single handpiece and having a main control valve regulating air-water flow to the handpiece it services. Diaphragms control the operation of the main control valves and a laminated base plate defines channels for air and water flow through the unit. A water pressure regulator and an air gauge are also provided in the system.
