    • The check valve (10) includes a valve housing (20,22), a valve body (24) and an urging member (25). The valve housing has a peripheral wall and a valve seat (20g). The peripheral wall has an opening (22b) therethrough for fluid communication. The opening is located more downstream than the valve seat. The end of the opening on the side of the valve seat is spaced at a predetermined length (a) in a direction in which the valve body is spaced away from the valve seat. A first throttle (26) is formed in a space between an inner peripheral surface (22e) of the valve housing and an outer peripheral surface (24f) of the valve body until the valve body is slid in the direction for the predetermined length from the state in which the valve body is seated on the valve seat.
    • 止回阀(10)包括阀壳体(20,22),阀体(24)和推压构件(25)。 阀壳具有周壁和阀座(20g)。 周壁具有用于流体连通的开口(22b)。 开口位于比阀座更下游的位置。 阀座侧开口的端部在阀体与阀座隔开的方向上以预定长度(a)间隔开。 在阀壳体的内周面(22e)和阀体的外周面(24f)之间的空间中形成第一节流阀(26),直到阀体沿着从阀体沿着预定长度方向 阀体位于阀座上的状态。
