Title
(EN) PNEUMATIC REMOVER FOR USE IN REMOVING DENTAL PROSTHETICS
(FR) EXTRACTEUR PNEUMATIQUE DE PROTHESES DENTAIRES
Abstract
(EN)
A pneumatic remover assembly having a central housing (3) with a reciprocating internal mass (11) and a spring (13), a first end unit (17) having a spool-type valve (19) for activating the remover, a second end unit (29) having various conduits disposed therein for introducing and exhausting compressed air in and out of the remover, and a unique adjustment ring (35) which is capable of adjusting the flow rate of the compressed air which is introduced to the remover, thereby regulating the striking intensity of the remover. The adjustment ring (35) comprises an airflow groove (51) disposed within the interior surface of the adjustment ring which is in contact with the second end unit (29) of the remover assembly. This airflow groove (51) has a gradually increasing depth along its length and is in continuous communication with the compressed air injection conduit (32) disposed in the second end unit.

Extracteur pneumatique de prothèses comportant un logement central (3) renfermant une masse interne à mouvement alternatif (11) et un ressort (13), une première unité finale (17) munie d'un robinet à tiroir (19) actionnant l'extracteur, une deuxième unité finale (29) comportant différents conduits internes d'admission et d'échappement de l'air comprimé alimentant l'extracteur et une bague spéciale de réglage (35) réglant le débit d'air comprimé admis, et par là, la force de la frappe de l'appareil. Ladite bague (35) comprend une rainure laissant passer l'air comprimé (51) pratiquée sur sa surface interne et qui est en contact avec la seconde unité finale (29) de l'extracteur. Ladite rainure (51) dont la profondeur croît le long de sa longueur communique en permanence avec le conduit d'admission (32) situé dans la deuxième unité finale.
