  "textContent": "A normally closed solenoid valve includes a fixed core (22), a valve portion including a valve seat (42) and a valve body (20), a movable core (32) disposed between the fixed core (22) and the valve seat (42), a resilient biasing member (34) for biasing the movable core (32) in a valve-closing direction and a coil (24). When energized, the coil (24) generates an attracting force between the movable core (32) and the fixed core (22) against a biasing force by the resilient biasing member (34) to cause the movable core to retreat from an initial position where the valve seat (42) is in a closed state. When a characteristic graph line of spacing distance/attracting force that defines the attracting force in relation with a spacing distance between the fixed core (22) and the movable core (32) provides an inclination A (N/mm) at the initial position, the compression resiliency coefficient of the resilient biasing member (34) is set to A(N/mm).",
