Fluid control system for dental console

摘要

This invention pertains to a dental operatory console system including one or more fluid control valves for driving air and water to be delivered to dental handpieces supported for ready removal from a pivoted holder to provide adjustable angular positioning of the handpiece, one of such pivoted holders being adjacent each control valve and including a lockout for the valve plunger when the handpiece is removed from the holder, such as when changing burs, to prevent accidental operation of the air and water valve for delivery to the handpiece. The pivoted holder is readily removable for servicing the valve and the fluid circuit for water and air between a source of the same and a plurality of handpieces in the console includes shuttle valves to permit the use of a single air pressure gage for the system rather than a gage for each handpiece as in conventional multiple-handpiece consoles.
