車用空気調和装置における圧力開放弁。 A pressure switch S that stops the operation of the compressor 1 when the pressure of the refrigerant in the high-pressure part Q of the cooling cycle falls below a predetermined value is provided in the high-pressure part Q, and communicates with the refrigerant flow path R in the cooling cycle. A cylindrical body 10 having an opening 15 formed therein is attached to the high pressure section, and a valve element 16 provided with a sealing material for closing the opening 15 is attached within the cylindrical body 10, and a valve element 16 is attached to the valve element 16. A spring member 20 that applies a resilient force in the direction of closing the opening is installed in the cylinder 10, and is positioned outside the opening 15 in the cylinder 10 so as to have a diameter larger than that of the opening 15. None Sliding seal surface 2 in contact with the valve body 16
4, so that when the pressure of the refrigerant becomes lower than the pressure set by the pressure switch S, the valve body closes the opening 15 by the elastic force of the spring member 20. A pressure release valve for an automobile air conditioning system.
