Abstract

L'ensemble de clapet est formé dans une plaque de clapet 66 et comprend un orifice de décharge 78 formant siège pour un élément de clapet 122 réalisé en un matériau léger et souple, par exemple en résine de polymère, le siège et l'élément de clapet ayant des conicités légèrement différentes de façon que la fermeture du clapet s'effectue de façon progressive tout d'abord par sa zone périphérique de plus grand diamètre sous la sollicitation d'un ressort de rappel, puis, par le jeu des différences de pressions de part et d'autre de l'élément de clapet, avec appui complet par déformation de ce dernier, contre le siège de façon que sa face inférieure 126 soit coplanaire avec la face inférieure 70 de l'élément de plaque. Un autre moyen de clapet 132, 134, 136 peut être avantageusement prévu au centre de l'élément de clapet pour augmenter le passage de décharge. Application, plus particulièrement aux compresseurs de systèmes de conditionnement ou d'échange de chaleur.The valve assembly is formed in a valve plate 66 and includes a relief port 78 forming a seat for a valve member 122 made of a light and flexible material, eg, polymer resin, the seat and the valve member. valve having slightly different conicities so that the valve is closed gradually firstly by its peripheral zone of larger diameter under the stress of a return spring, then by the play of the pressure differences on either side of the valve element, with complete support by deformation of the latter, against the seat so that its lower face 126 is coplanar with the lower face 70 of the plate element. Another valve means 132, 134, 136 may be advantageously provided at the center of the valve member to increase the discharge passage. Application, more particularly to compressors for conditioning or heat exchange systems.
