Abstract: An accumulator has a tank and a desiccant. The tank separates refrigerant flowing to the tank into vapor-phase refrigerant and liquid-phase refrigerant, therein stores the liquid-phase refrigerant, and emits the vapor-phase refrigerant toward a suction side of a compressor. The desiccant is disposed in the tank and removing a water content from the refrigerant. Liquid-phase refrigerant included in the refrigerant flowing to the tank drops downward from a location that is located above the desiccant, and is stored in a lower portion in the tank. Vapor-phase refrigerant included in the refrigerant flowing to the tank is drawn through a suction port that is located above the desiccant to flow out of the tank. At least a part of the desiccant is exposed to vapor-phase refrigerant under a normal condition, and the desiccant is located at a location that is away from a dropping route of liquid-phase refrigerant in the tank.
Abstract translation: 蓄能器有一个罐和一个干燥剂。 容器将流入罐的制冷剂分离为气相制冷剂和液相制冷剂，其中储存液相制冷剂，并将气相制冷剂朝向压缩机的吸入侧排出。 将干燥剂置于罐中并从制冷剂中除去含水量。 包含在流到罐中的制冷剂中的液相制冷剂从位于干燥剂上方的位置向下落下，并储存在罐的下部。 包含在流到罐中的制冷剂中的气相制冷剂通过位于干燥剂上方的吸入口被吸出以从罐中流出。 干燥剂的至少一部分在正常条件下暴露于气相制冷剂，并且干燥剂位于远离罐中液相制冷剂滴落路径的位置。

Abstract: An expansion valve is provided with a valve body including an inlet hole through which a refrigerant flows into a valve chamber, and a valve hole through which the refrigerant flows out of the valve chamber; a valve element configured to adjust an amount of the refrigerant flowing through the valve hole; a power element that is mounted to the valve body and configured to drive the valve element via a valve rod; a first vibration isolation spring provided in the valve chamber and configured to prevent vibration of the valve element; and a second vibration isolation spring that is in contact with the valve rod and configured to prevent vibration of the valve element.
