    Abstract: In a refrigerating apparatus comprising a rotary compressor, a pressure-controlled valve is inserted in a path between a condenser and an evaporator and a reverse flow check valve is inserted between the evaporator and a suction line connected to the input port of the rotary compressor, thereby to eliminate undesirable heat load caused by undesirable flow-in of the refrigerant gas into the evaporator after the rotary compressor stops.

    Abstract: In a refrigerating apparatus comprising a rotary compressor, a fluid-controlled valve is inserted in the path between a condenser and a evaporator and a reverse flow check valve is inserted between the evaporator and a suction line connected to the input port of the rotary compressor. Unwanted heat load caused by flow of high pressure refrigerant into the evaporator, then the rotary compressor stops, is thereby eliminated.

    Abstract: PURPOSE:To prevent a hydrocarbon of a foaming agent from being exploded, since even if static electricity which is apt to be generated by progressing the foaming of a foamed heat insulation material is led outside, by a method wherein a wall surface of an inner box comprised of a synthetic resin on the foamed heat insulation material side is made into the same electric potential as that of an outer box by applying a conductive coating to the wall surface. CONSTITUTION:A heat insulation box body 1 of a refrigerator is formed of a metallic outer box 2, an inner box 3 made of a synthetic resin and a foamed heat insulation material 4 wherein a hydrocarbon filled into a space between both the boxes 2, 3 is taken as a foaming agent. In the outer box 2, a double flange 5 is formed on a front edge of an opening, in which an outward flange 6 formed on the front edge of the opening of the inner box 3 is inserted. A conductive coating 7 is applied to the surface of a foamed heat insulation material side of the inner box 3. The conductive coating 7 is positioned at the flange also, joined electrically to the double flange 5 of the outer box 2 and formed into the same electric potential as that of the outer box 2. Hereby, it becomes earthable easily through the outer box 2. Such a hazard that the circumference is destroyed by an explosion of a foaming agent during a foaming operation of a heat insulation material is eliminated.

    Abstract: PURPOSE:To prevent a diaphragm from being deformed by welding by disposing a circular groove between the inner periphery of a flange for fixing a diaphragm and the outer peripheral end of a flange joined to a casing by fusing. CONSTITUTION:A circular groove 24c is formed at the substantially central part of a diaphragm flange 24a of a diaphragm 24. The inside 24d of the circular groove 24c is fixed to the lower surface of an upper casing flange 22a at the upper surface of an inner flange 23c of an engaging portion 23b of a lower casing flange 23a. Though at the time of welding, the diaphragm 24a contracts inward, the circular groove 24c contracts radially, so that stress strain is prevented from being transmitted to the inside 24d of the circular groove.
