Summary of the dental handpiece
Summary of the dental handpiece
Therefore, it is the primary object of the present invention to provide dental handpieces of the above-described type in which the problems and disadvantages of the solutions described above are eliminated.
In accordance with the present dental equipment, at least one opening in the turbine chamber wall in the area near the axis is connected through a connecting duct to the return duct.
In accordance with a first embodiment, which is based on the same basic solution, the connecting duct ends in the receiving bore of the dental high speed handpiece head on the side of the tool of the bearing located on the side of the tool. As a result of this measure, when the turbine runs out after the propulsion air has been interrupted, the still rotating turbine produces a closed air flow from the periphery of the rotor through the return duct, the connecting duct and the opening near the axis into the turbine chamber, wherein this configuration ensures that essentially no air is taken into the interior of the handpiece along the tool shaft and through the roller bearings. Consequently, when the handpiece is once again operated, no contaminations are blown out of the interior of the handpiece.
In accordance with an advantageous further development of the first embodiment described above, the turbine chamber is constructed in the area of the opening for the connecting duct as an annular chamber which is in communication with the actual turbine chamber only through an annular gap near the axis. This embodiment has the advantage that only a very small amount of air flows off through the connecting duct during operation, because the centrifugal acceleration causes the propulsion air to be guided to the periphery of the turbine chamber and a significantly lower excess pressure exists in the area near the axis than in the peripheral area of the rotor. In this manner, the measure according to the present dental autoclave only insignificantly impairs the efficiency of the turbine.
The various features of novelty which characterize the dental handpieces are pointed out with particularity in the claims annexed to and forming a part of the disclosure. For a better understanding of the invention, its operating advantages, specific objects attained by its use, reference should be had to the drawing and descriptive matter in which there are illustrated and described preferred embodiments of the invention.
