Title
(EN) VALVE, PARTICULARLY FOR COMPRESSORS, WITH VALVE FACE HAVING A SHAPED PROFILE
(FR) SOUPAPE, NOTAMMENT UNE SOUPAPE DE COMPRESSEUR AYANT UN COLLET PROFILE
Abstract
(EN) Valve, preferably for compressors, comprising a seat (2; 4) in which there are formed one or more flow apertures (102; 104), positioned with their axes parallel to that of the said seat (2; 4), and a valve face member movable in a direction parallel to the axis of the said seat, comprising one or more valve face elements (1; 3) capable of interacting with the said apertures (102, 104) formed in the said seat (2; 4); each valve face element (1; 3) has, on the surface facing the said aperture (102; 104), a concave profile (111; 113) which is symmetrical with respect to the axis of the corresponding aperture.
(FR) L'invention concerne une soupape, notamment une soupape de compresseur, comprenant un siège (2; 4) pourvu d'une ou plusieurs ouvertures d'écoulement (102; 104) positionnées de façon que leurs axes soient parallèles à l'axe du siège (2; 4), et un collet de soupape mobile dans une direction parallèle à l'axe du siège et comprenant un ou plusieurs éléments de collet de soupape (1; 3) capables d'interagir avec lesdites ouvertures (102, 104) pratiquées dans le siège (2; 4); chaque élément de collet de soupape (1; 3) comprend, sur la surface faisant face à ladite ouverture (102; 104), un profil concave (111; 113) symétrique par rapport à l'axe de l'ouverture correspondante.
