    摘要: Disclosed is a composite valve comprising a valve body that is provided integrally with a solenoid valve portion and a differential pressure valve portion. The valve body is formed with an upper valve chest, a lower valve chest, a refrigerant introduction chamber that communicates with the upper valve chest and has a differential pressure valve seat, and a back pressure introduction chamber that communicates with the lower valve chest. A main valve element that is opened and closed by means of the solenoid valve portion is located between the upper valve chest and the lower valve chest. A differential pressure valve element that is opened and closed by means of a differential pressure between the refrigerant introduction chamber and the back pressure introduction chamber is located between these two chambers. The refrigerant introduction chamber, back pressure introduction chamber, and differential pressure valve element are arranged so as not be situated on the outer surface of the valve body.
