To improve response to low pressure, in a pressure control valve.SOLUTION: A pressure control valve (10) comprises: a housing (20) having a first flow passage part (95), a second flow passage part (96) having a flow passage cross-sectional area larger than that of the first flow passage part (95) and a third flow passage part (97) communicating with the second flow passage part (96) via a valve opening (90); a partition part (30); a valve seat (35) continuous with the partition part (30) and formed around the valve opening (90); a valve body (40) configured so as to be seated on the valve seat (35); a pressure receiving member (60) configured to be movable over the inside of the first flow passage part (95) and the inside of the second flow passage part (96) and including a pressure receiving surface (61); and a compression coil spring (50) that causes the valve body (40) to be seated on the valve seat (35). The pressure receiving surface (61) has an area (S2) larger than a flow passage cross-sectional area (S1) of the valve opening (90). The pressure receiving member (60) closes the first flow passage part (95) in a state where the valve body (40) is seated on the valve seat (35).SELECTED DRAWING: Figure 1
【課題】圧力制御弁において低圧に対する応答性を向上させる。【解決手段】圧力制御弁(10)は、第1流路部(95)と、第1流路部(95)よりも大きい流路断面積を有する第2流路部(96)と、第2流路部(96)と弁開口(90)を介して連通する第3流路部(97)と、を有するハウジング(20)と、仕切部(30)と、仕切部(30)と連なり弁開口(90)の周りに形成された弁座(35)と、弁座(35)に着座可能に構成された弁体(40)と、第1流路部(95)内と第2流路部(96)内とに亘って移動可能に構成され受圧面(61)を含む受圧部材(60)と、弁体(40)を弁座(35)に着座させる圧縮コイルばね(50)とを備え、受圧面(61)は弁開口(90)の流路断面積(S1)よりも大きい面積(S2)を有し、受圧部材(60)は弁体(40)が弁座(35)に着座した状態において第1流路部(95)を塞ぐ。【選択図】図1
