ABSTRACT:
A multi-chamber expansion device for a vehicle cooling or heating circuit consists of a single vessel in which the three successive chambers of the expansion device are aligned horizontally within a rigid elongate casing, which is formed by two moulded hollow members welded together along their respective peripheral edges in a vertical junction plane. These edges are thickened and formed with a groove which extends over substantially the whole periphery of the vessel, at the joint between the two casing members. This groove is interrupted by integral bridges so as to define ducts which connect together, firstly the first and second chambers, and secondly the second and third chambers, through a pressure-limiting valve.
