    • In a four-way valve having a simple structure, even if a high-temperature refrigerant and a low-temperature refrigerant flow close to each other, heat loss between both refrigerants is suppressed. The valve comprises a housing member including a valve chamber, a valve seat including a bearing surface portion located in the valve chamber, a first channel through which a high-temperature fluid flows and a second channel through which a low-temperature fluid flows at a predetermined time, including openings adjacent to each other at a bearing surface portion of the valve seat, passing through the valve seat and extending outside of the valve chamber, and a valve element moving to the bearing surface portion of the valve seat. A thermal resistor portion suppressing heat transfer between these channels is located near the openings, between the first and second channels.
    • 在具有简单结构的四通阀中,即使高温制冷剂和低温制冷剂彼此接近,也抑制了两种制冷剂之间的热损失。 阀包括壳体构件,其包括阀室,阀座,其包括位于阀室中的支承表面部分,高温流体流过的第一通道和低温流体在其中流动的第二通道 预定时间,包括在阀座的轴承表面部分处彼此相邻的开口,穿过阀座并延伸到阀室外部;以及阀元件移动到阀座的支承表面部分。 抑制这些通道之间的热传递的热电阻部分位于第一和第二通道之间的开口附近。
