Abstract
A fluid control valve includes a first flow path and a second flow path that connect a first port and a second port in parallel. The first flow path includes an opening and closing valve mechanism that temporarily opens the first flow path. The second flow path includes a throttle valve mechanism that restrictedly opens the second flow path. The opening and closing valve mechanism includes an opening and closing valve portion including an opening and closing valve seat and an opening and closing valve body, a valve opening force generator, and a delay valve closing mechanism that closes the opening and closing valve body after a delay time has elapsed. The throttle valve mechanism includes a throttle valve portion. The opening area of the opening and closing valve portion is larger than the opening area of the throttle valve portion.
