摘要：
A coupling system that provides air to a dental handpiece having a movable tip driven by the air, comprising:
(i) a female assembly having a passageway for drive air to drive the tip comprising a diameter having a predetermined axial location,
(ii) a male assembly having a passageway for drive air to drive the tip further comprising a movable ring having a first position that blocks the drive air passageway when the male assembly is removed from the female assembly, and having a second position that retracts from the drive air passageway when the male assembly is assembled to the female passageway, thereby providing an aperture of predetermined size for flow of drive air from the drive air passageway in the male assembly to the drive air passageway in the female assembly as a result of movement of the ring due to contact with the diameter in the female assembly.
