摘要： PROBLEM TO BE SOLVED: To quicken the response corresponding to gas low condition and protect a compressor without fail, by stopping the compressor through an electric contact which closes when the piston shifting according to the pressure difference between the pressure of the suction gas refrigerant sucked in the compressor of a freezer and atmospheric pressure shifts by a specified quantity. SOLUTION: In operation of an air conditioner for a vehicle, when the load of the air conditioner is small, if the pressure within a pressure chamber 25 leading to a suction chamber 13 drops, a piston 21 shifts right and left, according to the pressure difference between the pressure of a suction gas refrigerant and the atmospheric pressure. Then, a suction gas refrigerant passage 10 is throttled by the cut 29, and the quantity of a gas refrigerant sucked in the compressor becomes small, and the capacity of the compressor 1 drops. When it comes to gas low condition by the leakage of the refrigerant charged in a refrigerant circuit, the pressure of the suction gas refrigerant drops more, and the piston 21 shifts right more, and the electric contact 31 contacts with an electric contact 32, whereupon the electric circuit leading to an electromagnetic clutch becomes ON, and the electromagnetic clutch becomes OFF, and the compressor stops.

摘要： PROBLEM TO BE SOLVED: To prevent a fastening means from breaking due to corrosive fatigue by covering the surface of the fastening means fastening a plurality of housing elements on the suction chamber side with chemical conversion coatings of chromate. SOLUTION: The surfaces of a plurality of bolts 3 for fastening a main body 2 constituting a housing 1 with a front housing 4 is covered with chemical conversion coatings of chromate. This chemical conversion coatings are constituted by films of zinc flake layers laminated by the use of water-soluble amorphous trivalent chromium polymer as binder. This films prevent electrolytic corrosion due to potential difference between the housing 1 made of aluminum and the bolts 3 from generating by self-sacrifice protecting action of zinc flake, passivation of the surface of the bases of the bolts 3 by chromic acid, barrior action of zinc flake and chromium compound, and their synergism.
