Abstract

Dispositif de décompression pour installation de graissage centralisée du type comportant une pompe à débit alternatif et à légère fuite raccordé à un circuit à pression intermittente commandant les distributeurs de graissage par l'intermédiaire d'un clapet à double effet produisant la mise à la décharge dudit circuit lors de l'arrêt de la pompe, et un accumulateur formé par une chambre cylindrique verticale contenant avec un très faible jeu une bille et alimentant par sa sortie inférieure obturable par la bille l'espace situé en amont du clapet de décompression, tandis que le circuit est raccordé à l'espace entre le joint à lèvres du clapet et son joint en bout obturant l'orifice de décharge, dispositif caractérisé par le fait que ladite chambre cylindrique verticale est disposée axialement à l'intérieur du clapet à double effet, dimensionné en conséquence, le raccordement hydraulique de cette chambre cylindrique étant assuré par un simple trou transversal à sa partie supérieure et par un trou axial à sa partie inférieure raccordée à la sortie de la pompe.
