To provide a steam pressure regulating valve which can properly exert a heat absorption effect of an evaporator while suppressing the deterioration of mountability, and a refrigeration cycle device.SOLUTION: A refrigeration cycle device 10 comprises a compressor 11, an indoor condense 12, a first expansion valve 15a, a second expansion valve 15b, an outdoor heat exchanger 16, an indoor evaporator 18 and a steam pressure regulating valve 19. The steam pressure regulating valve 19 includes a microvalve as a valve component for switching an adjusting state for adjusting a throttle opening, and a full-open state. The microvalve has a drive part which is displaced by a temperature change, an amplification part for amplifying the displacement of the drive part caused by the temperature change, and a movable part for adjusting a flow rate of a refrigerant flowing in the steam pressure regulating valve by moving by being transmitted with displacement amplified by the amplification part. Then, the amplification part is constituted so as to function as a lever with a hinge as a pivot, with an energization position in which the amplification part is energized by the drive part as a power point, and with a connecting position between the amplification part and the movable part as a point of action.SELECTED DRAWING: Figure 1

    【課題】搭載性の悪化を抑制しつつ、蒸発器の吸熱効果を適切に発揮させることが可能な蒸発圧力調整弁および冷凍サイクル装置を提供する。【解決手段】冷凍サイクル装置10は、圧縮機11、室内凝縮器12、第1膨張弁15a、第2膨張弁15b、室外熱交換器16、室内蒸発器18、蒸発圧力調整弁19を備える。蒸発圧力調整弁19は、絞り開度を調整する調整状態と全開状態とに切り替えるための弁部品としてマイクロバルブを含んでいる。マイクロバルブは、温度変化によって変位する駆動部と、駆動部の温度変化による変位を増幅する増幅部と、増幅部によって増幅された変位が伝達されて動くことで、蒸発圧力調整弁を流れる冷媒の流量を調整する可動部と、を有する。そして、増幅部が、ヒンジを支点とし、増幅部が駆動部に付勢される付勢位置を力点とし、増幅部と可動部との接続位置を作用点とする梃子として機能するように構成されている。【選択図】図1
