Abstract

Expansion vessel for hydraulic installations perfected, consisting of a tank composed of two bodies facing each other and joined together, in whose reservoir there is lodged an elastic membrane that determines the inner and incommunicated chambers, one containing nitrogen gas that is filled at a certain pressure and the other communicated with the hydraulic fluid of the installation, essentially characterized in that said bodies have, constituted, in relation to their respective embouchure, an outer rim, formed by a circular and continuous fin, which observes a certain divergent inclination starting from its beginning, to then experience a break in the opposite direction that generates a short peripheral skirt, whose free edge exceeds the level of the embouchure of the corresponding body, said flanges being provided to cooperate, in the connection with removable character between both bodies, with some closing pieces conforms they are made of resistant sheet metal, which observe a general configuration in the form of sector of circular crown and of cross section in "U" with the rounded inner and outer vertices and whose branches offer a certain convergence from the soul of the piece; all structured so that the aforementioned flanges are capable of accommodating between them, in the facing arrangement of the bodies or assembly of the vessel, the annular and thickening flange with which it has been foreseen to equip the membrane, being sufficient already with previously compressing the aforementioned flange with the bodies and then proceed with the placement of the pieces so that, when used in a suitable number according to the volume of the vessel, when the compression stops, the elasticity of the aforementioned flange forces those, given their configuration, to be fitted in perfect adaptation to the contouring of the flanges, so that the joint of the assembly will be no longer secure, since the aforementioned flange will be trapped and retained under pressure between the flanges, establishing a perfect tightness in the closure.
