摘要： An air conditioner has a refrigerant circuit 1 in which a refrigerant flows through a compressor 2, a condenser 3, a supercooling heat exchanger 10, a first expansion mechanism 4 and an evaporator 5 in this order. In this refrigerant circuit 1, the refrigerant discharged from the compressor 2 is condensed in the condenser 3 and the condensed refrigerant is supercooled in the supercooling heat exchanger 10. This refrigerant is reduced in pressure in the first expansion mechanism 4, thereafter evaporated in the evaporator 5 and sucked into the compressor. Use of a nonazeotrope refrigerant as the above refrigerant can increase the refrigerating capacity improving effect due to supercooling as compared with the case where a single refrigerant is used.

摘要： Formed in a valve main body (1) is a refrigerant flow path (41) for lowering the amount of flow of a refrigerant which flows into an internal space (30) of a casing (3) from a refrigerant flow path (9) through a needle fit/insert clearance (17) defined between a needle fit/insert aperture (16) and a needle (2) inserted into the needle fit/insert aperture (16). When, with the rise or drop in refrigerant pressure, refrigerant flows through the needle fit/insert clearance (17), adhesion of sludge included in the refrigerant to the wall surface of the needle fit/insert clearance (17) is reduced by a lessened amount of refrigerant flow in the needle fit/insert clearance (17) by the refrigerant flow path (41). This therefore prevents, as far as possible, malfunction of the needle (2) due to sludge adhesion, thereby ensuring proper operation of the needle (2).
摘要翻译：形成在阀主体（1）中的制冷剂流路（41）是用于降低从制冷剂流路（9）流入壳体（3）的内部空间（30）的制冷剂的流量通过限定在针配合/插入孔（16）和插入针配合/插入孔（16）中的针（2）之间的针配合/插入间隙（17）。当制冷剂压力升高或降低时，制冷剂流过针头配合/插入间隙（17），包含在制冷剂中的污泥与针配合/插入间隙（17）的壁表面的粘附被减少通过制冷剂流路（41）在制针/插入间隙（17）内的制冷剂流量。因此，尽可能地防止由于污泥附着而导致针（2）的故障，从而确保针（2）的适当的操作。

摘要： A bridge circuit (11) having four check valves (31, 32, 33, 34) is provided upstream of a receiver (10), which is provided upstream of an expansion valve (7). A gas vent pipe (12) for connecting the receiver (10) and a pipe (24) downstream of the expansion valve (7) to each other is provided, and the gas vent pipe (12) is provided with a gas vent valve (13). Upon shut down, the gas vent valve (13) is opened, and the expansion valve (7) is gradually closed. The compressor (4) is shut down and the gas vent valve (13) is closed after passage of a predetermined time from the point in time when the expansion valve (7) reaches the fully closed state.

The main body forms a push rod storage space, a communication path, a seal structure forming part and a male thread part. The push rod storage space houses the push rod so that one part of the push rod protrudes along a push rod longitudinal direction. The seal structure forming part is capable of forming a seal structure by contacting a first tapered part of the nut member. The male thread part is capable of screwing together with a female thread part of the nut member such that the seal structure forming part contacts the first tapered part. The part of the portion of the push rod contacts one part of the nut member.
