The present invention provides a pressure adjustment valve capable of suppressing pressure loss of a refrigerant toward a secondary side flow path. A pressure adjustment valve (10) is provided with: a valve body (11) having a primary port (11A), a secondary port (11B), and a valve seat part (11C); a valve body (12); a bellows (13); a valve spring (14); and a support member (23) that supports the bellows (13) on the valve body (11). The support member (23) has a plurality of extension sections (234) extending radially outward from the annular section (233), and the extension sections (234) are provided with rectifying means for rectifying the refrigerant flowing from the primary side to the secondary side.
本发明提供一种能够抑制朝向二次侧流路的制冷剂的压力损失的压力调整阀。压力调整阀(10)具备:阀主体(11),其具有一次侧端口(11A)、二次侧端口(11B)以及阀座部(11C);阀芯(12);波纹管(13);阀簧(14);以及支撑部件(23),其将波纹管(13)支撑于阀主体(11)。支撑部件(23)具有从环状部(233)向径向外侧延伸的多个延伸部(234),在延伸部(234)设置有对从一次侧向二次侧流动的制冷剂进行整流的整流单元。
