ABSTRACT:
A stopper (11) is disclosed for fixing to the end of an inlet tube (10) to a heat exchanger circuit such as a radiator for an internal combustion engine or an associated expansion chamber. The stopper comprises a body (12) housing a set of rated overpressure and underpressure valves (27 to 33) and a cylindrical skirt (15) having bayonet-fixing means (20) for fixing to the end of the inlet tube. The set of valves is mounted on a plate (21) located inside the stopper housing and so arranged as to enable direct communication independently of the set of valves between the inside and the outside of the heat exchanger circuit when the stopper is in an intermediate position between its position for fully closing the inlet tube and its open position, the communication being prevented when the stopper is in the fully closed position.
