Abstract
An apparatus for supporting and controlling fluid delivery to a dental handpiece includes a frame with a holder for receiving the handpiece, a compressed air actuating arrangement having a valve which is opened and closed by the insertion and removal of the handpiece into and from the holder, and fluid delivery tubing which extends to the handpiece and is affixed at spaced locations to the frame and to the actuating arrangement for folding of the tubing upon itself to close the tubing against fluid flow when the handpiece is mounted in its holder and for unfolding the tubing for open fluid flow when the handpiece is removed from the holder.
