Abstract: A three-way electromagnetic valve controls the opening and closing of a fuel injection valve by enabling a back pressure chamber in which fuel for serving to bias a nozzle needle of the fuel injection valve in the valve closing direction is stored to communicate alternatively with a high pressure chamber in which a high pressure fuel is stored or a low pressure chamber in which a low pressure fuel is stored, and is prevented from any accumulation of extraneous material in clearances of a sliding portion.

Abstract: A refrigerant receiver of elongated pipe 4 shape arranged in front of a refrigerant condenser 3. The receiver is of a dimension matched to that of the condenser, and has an inlet 34 for connection with the condenser section 13 and an outlet 38 for connection with a supercooler section 14. The receiver has inclined pipe portions 35 and 37 having inclinations to the horizontal direction, between which a bent portion 36 is arranged. No bubble is created in the refrigerant in the receiver irrespective of large values of the inclination of the receiver, thereby allowing only the liquid phase refrigerant to flow into the supercooler 14 from the outlet of the receiver 4.
