1,072,474. Refrigerators. SIEMENS-ELECTROGER€TE G.m.b.H. July 15, 1964 [July 15, 1963; Aug. 2, 1963], No. 29154/64. Heading F4H. A compressor type refrigerator comprises an evaporator 6 which cools a low temperature compartment 7 and a normal cooling compartment 8 heat insulated therefrom by walls 9, the temperature of the normal cooling compartment being regulated by a flap 10 or other throttling member which is controlled by a bellows-type thermostat 16 and regulates the flow of cold air from compartment 7 to compartment 8. The temperature of compartment 7 is controlled by a thermostat 20 which controls the operation of a compressor 4. The evaporator comprises wire-ribbed tubing bent to a U-shape and a drip channel 12 of a corresponding U-shape (Fig. 2, not shown), the whole, together with the heat insulating walls 9, 11, being assembled as one unit and installed in the refrigerator through aperture 18. Fig. 3 shows a pivoted control flap 101 provided in a side wall of the evaporator compartment 102, and actuated by a heat-sensitive bellows 110. A spring 107 returns the flap to the closed position when the bellows contracts. The flap may alternatively comprise the normal front access door of the evaporator compartment, Fig. 4 (not shown), the door in this ease being urged towards its closed position by a torsion spring 125. In this embodiment the spring bellows is supported by a bracket 123 on a side wall 124 of the compartment 7. The spring bellows is protected from excess pressure on the flap by a safety spring 126, Fig. 4 (not shown), and by a protective shutter 127, Fig. 5 (not shown).
