Abstract (en)
[origin: WO9314713A1] In order to give rotational speed of preferably 180,000 to 200,000 rpm, the invention proposes that the air-powered turbine (5), which in prior art dental handpieces is fitted in the head (4) of the handpiece, be mounted in the handle (3) and a reduction gear (2, 2') used to enable the turbine to be run at lower speeds.
Abstract (fr)
Afin d'atteindre une plage de vitesse de rotation comprise de préférence entre 180,000 et 200,000 t/mn, une turbine (5) à air comprimé, telle qu'elle figurait jusqu'à maintenant dans la tête (4) de la pièce à main, est disposée dans le manche (3). Un démultiplicateur (2, 2') permet de réduire la vitesse de rotation.
