Abstract (en)
[origin: EP0791733A1] Three expansion chambers (10,11,12) are horizontally aligned in a long rigid casing (1). The casing is formed from two hollow moulded parts welded at their peripheral edges (8) in a vertical joint plane. These edges are thickened and hollowed by a groove (20) extending along their periphery. This groove define a conduits (31) connecting the first and second chambers through a pressure limiting valve (36), and discharging in the upper part of the first chamber. The pressure limiting valve opens to allow discharge of liquid or gas from the second chamber when its pressure attains a predetermined value. The second and third chambers are connected by a second conduit (32,33) through the first valve. A second pressure limiting valve (44) carried by this conduit enables fluid from the third chamber to discharge into the second chamber.
