Driving method and device for dental hand-piece |
摘要 |
This disclosure relates to an improved method for driving a hand-piece of the air drive type to improve its cutting performance, and to increase its cutting load in a low range of rotational speed in particular, and also relates to a device for practicing the method. The disclosed method employs compressed high-velocity fluid exhausted to one side of an annular space in which blades rotate after having once been jetted at said blade guided along the rotating direction of said blades and then causing it to reenter the annular space in a diagonal direction with respect to the rotational direction of the blades for further driving the running blades in the same sense. The device includes a simply machined ring-shaped adapter.
