To improve responsiveness in opening a pressure control valve.SOLUTION: A pressure control valve (100, 100a) includes a housing (10, 10a) having an opening portion (13) for communicating a fluid inflow portion (11, 11a) with a fluid outflow portion (12, 12a), a valve element (50) having a valve portion (51) for sealing the opening portion (13) in a valve closed state, and a coil spring (60). In the housing (10, 10a), a first part (15) in which a clearance (C1) between itself and the valve element (51) along a radial direction orthogonal to a moving direction (D) is 0.02 mm or more and 0.5 mm or less, and a second part (16) connected to a fluid outflow portion (12) side of the first part (15) and having a flow channel cross-sectional area larger than that of the first part (15), are formed. A valve closing state is switched to a valve opening state by movement of the valve element (50) by a predetermined distance (L1) of 0.2 mm or more and 1.5 mm or less along the moving direction (D) while keeping the clearance (C1) in the valve closed state.SELECTED DRAWING: Figure 1

    【課題】圧力制御弁の開弁時の応答性を向上する。【解決手段】圧力制御弁(100、100a)は、流体流入部(11、11a)と流体流出部(12、12a)とを連通させる開口部(13)を有するハウジング(10、10a)と、閉弁状態において開口部(13)を封止する弁部(51)を有する弁体(50)と、コイルバネ(60)とを備え、ハウジング(10、10a)には、移動方向(D)と直交する径方向に沿った弁部(51)との間の隙間(C1)が閉弁状態において0.02mm以上0.5mm以下である第1部分(15)と、第1部分(15)の流体流出部(12)側に連なり第1部分(15)よりも流路断面積の大きい第2部分(16)とが形成されており、移動方向(D)に沿った0.2mm以上1.5mm以下の予め定められた距離(L1)を閉弁状態における隙間(C1)を維持して弁体(50)が移動することにより、閉弁状態から開弁状態に切り替わる。【選択図】図1
