<p>Accumulator device for a hydraulic installation which includes an interior membrane (2), said membrane (2) forming a fluid-accumulation cavity. It is characterised in that the membrane (2) includes a fold (2a) which forms two sections, a first section from the wall of the cylindrical body (1) to said fold (2a) and a second section from said fold (2a) to the moving support element (3), with the fold zone (2a) moving as the moving support element (3) moves. It allows sufficient volumes of water accumulation to space apart the starting and stopping of the electrically-driven pump, but with small diameters of the membrane's moving support element.</p> |
