ABSTRACT:
By the use of the suction pressure of a compressor, the pressure in back pressure chambers71gand71hare reduced to open a refrigerant inlet side and a refrigerant outlet side of an evaporator, and when the compressor is at rest, by the use of a first coil spring76and a second coil spring77, the refrigerant inlet side and the refrigerant outlet side of the evaporator40are closed mechanically. Due to this, it is possible to minimize a refrigerant leak by the use of an inexpensive means.
