    • A pressure regulating valve comprises a first pressure deformation part (120) receiving the pressure on the fuel demand side and deformable and a second pressure deformation part (130) so installed as to face the first pressure deformation part (120), receiving a predetermined pressure, and deformable. A first flow passage (140), a second flow passage (150), and a communication passage (160) allowing the first and second flow passages (140, 150) to communicate with each other are formed in the space between the first and second pressure deformation parts (120, 130). The pressure regulating valve further comprises a valve member (170) having a valve element (172) which has a connection part (171) extending through the communication passage (160) and connecting the first pressure deformation part (120) to the second pressure deformation part (130), installed in the connection part (171), and closing the communication passage (160) when moved to the second pressure deformation part (130) side. When the pressure on the fuel demand side is lower than a predetermined value, the valve element (172) does not close the communication passage (160). However, when the pressure on the fuel demand side is equal to or more than the predetermined value, the valve element (172) closes the communication passage (160).
    • 压力调节阀包括接收燃料需求侧和可变形的压力的第一压力变形部分(120)和安装成面对第一压力变形部分(120)的第二压力变形部分(130),接收预定压力 ,并可变形。 第一和第二流动通道(140),第二流动通道(150)和允许第一和第二流动通道(140,150)彼此连通的连通通道(160)形成在第一和第二流动通道 压力变形部件(120,130)。 压力调节阀还包括具有阀元件(172)的阀构件(170),阀元件(172)具有延伸穿过连通通道(160)的连接部分(171),并将第一压力变形部件(120)连接到第二压力变形 部件(130),安装在连接部分(171)中,并且当移动到第二压力变形部分(130)侧时关闭连通通道(160)。 当燃料需求侧的压力低于预定值时,阀元件(172)不关闭连通通道(160)。 然而,当燃料需求侧的压力等于或大于预定值时,阀元件(172)关闭连通通道(160)。
