A VACUUM-BREAKING VALVE FOR REFRIGERATION APPLIANCES

摘要

A vacuum-breaking valve for refrigeration appliances, comprising: a tubular body (10) made of a thermally conductive material and mounted through one of the walls of a cabinet (G) of the refrigeration appliance; a valve seat (30) mounted to the tubular body (10); a sealing means (40) constantly biased towards a closed position, in which it is seated on said valve seat (30), and movable towards an open position when the pressure inside cabinet (G) is lower than the pressure outside said cabinet (G); and a heat collector (20) provided with a thermal radiation collecting surface (21) mounted to the tubular body (10) and facing a heat source external to cabinet (G).
