Abstract
A dental handpiece includes a base member detachably connected to a hollow portion of a grip piece which has a turbine head with at least one consumer point which includes a pressure-driven turbine. To convey a pressure medium from a supply hose, a separate flexible conduit for each type of medium extends through a separate passageway in the base member to terminate at a common connecting member which has a passage for each conduit and is held in communication with fixed bores or ducts in the turbine head. The connecting member is held in fluid communication either by a spring or by a threaded fastener. In order to control the amount of fluid flowing through each of the flexible conduits, each flexible conduit may be provided with means for partially collapsing the conduit to cause a restriction in the flow through volume.
