(54)	Pressure-compensating valve for refrigerating chambers

(57) This valve consists of two ventilators (1 and 2), each of which is driven by an independent motor (la and 2a), the motors being of equal power, an electric control circuit (3), some LED's (4) indicating the operational status of the ventilators (1 and 2), a heating element (5) for heating the valve unit, a pipe (6) to channel the flow of air produced by the ventilators (1 and 2) and two grates at each end (7 and 8). The pipe (6) is mounted in an opening made in a wall (9) of the refrigerating chamber and has the grates (7 and 8) at each end. The ventilators (1 and 2) are mounted by means of a housing (10) inside the pipe (6), and each one projects a flow of air (1b and 2b) towards the interior and the exterior of the refrigerating chamber respectively.
