ABSTRACT:
A multiple dental handpiece control system is disclosed including a separate control valve block for each handpiece with multiple air and water passages through the valve block. A flexible sleeve is provided surrounding each fluid passage which, when pressure is supplied to its exterior, will collapse about a central fitting in each passage preventing flow from inlet to outlet openings in the central fitting. Pressure in the chamber surrounding the flexible sleeve is relieved when the dental handpiece is removed from its holder and is restored when the handpiece is returned to its holder.
