Refrigeration circuit for cooling installations including a plurality of refrigerated chambers, and bistable switching solenoid valve usable in such a circuit.
<??>The refrigeration circuit comprises a compressor 1, a condenser 2 and several evaporators 5, 6 each of which is associated with one of the refrigerated chambers. In order to allow communication between the condenser 2 and one or more of the said evaporators 5, 6, a bistable switching solenoid valve is used which is capable of changing state each time it receives an excitation pulse, and of remaining in one or the other of the two stable states when it is not excited.
<??>The invention further relates to an embodiment of this bistable switching valve.
