REFRIGERATOR OR FREEZER INCLUDING A DEFROST APPARATUS

摘要

A refrigerator and/or freezer apparatus comprising a regulating device of a flux is proposed for regulating a fluid flow through an orifice (212), said device comprising a fluid interception member (220) being associated to the orifice, responsive to the fluid pressure whose flux through the orifice is desired to regulate. The fluid interception member has a first operative configuration corresponding to a pressure value of the fluid lower than a predetermined value, in said first operative configuration the interception member closing the orifice in order to prevent the passage of the fluid, and a second operative configuration corresponding to a pressure value of the fluid at least equal to said predetermined pressure value, in said second operative configuration the interception member opening the orifice in order to allow the passage of the fluid. In the solution according to an embodiment of the present invention, said device is configured in such a way that the return of the interception member from the second to the first operative configuration relies on the action of the gravity force naturally acting on the interception member itself.
