Abstract: L'invention concerne un dispositif d'inhalation (1) destiné à libérer un produit. Le dispositif comporte un logement (2) destiné à recevoir un contenant (3) pressurisé de libération de produit et doté d'une partie (8) conçue pour loger une tige de soupape (9) dudit contenant pressurisé; un orifice d'entrée d'air vers ledit logement; et un embout buccal (7). Le dispositif comporte en outre un élément conduit qui communique avec le logement dans le but d'acheminer le produit vers l'embout buccal, et une unité de régulation du flux d'air prenant la forme d'une membrane circulaire (12) située à proximité de la partie logeant la tige de soupape. L'unité de régulation du flux d'air (12) passe dans une première position correspondant à un flux d'air nul, ou à un flux d'air minimal, de l'orifice d'entrée vers l'embout buccal. En cours d'utilisation, on peut faire passer ladite unité de régulation dans une seconde position, correspondant à un flux d'air maximal se produisant de l'orifice d'entrée vers l'embout buccal, et ce, par l'intermédiaire du contenant pressurisé de libération de produit. Le déplacement prolongé dudit contenant pressurisé provoque la libération d'une dose de produit dans le flux d'air maximal créé par un utilisateur qui applique une succion sur l'embout buccal.

Title: Rodless slides
Inventor: MORR GLEN A
IPC: F15B15/08
Filed: 2000-03-14
Abstract: Internal bearing assemblies for a rodless slide assembly. The internal bearing assemblies are positioned in bearing slots which are provided in portions of a transmission bracket and include inner bearing members and outer bearing shell members. Force applied to the internal bearing members causes them to slide up inclined surfaces of the bearing slots. The inner bearing members press against the outer bearing shell members which in turn press against the inner surface of the rodless slide bore. As a result, a radially inward force is applied to the transmission bracket. This radially inward force is transmitted to a saddle and external bearing assembly.      The internal bearing assemblies thus hold the saddle against the outer surface of the rodless slide.
