Patent number: 7240893Abstract: A normally closed solenoid valve includes a fixed core, a valve portion including a valve seat and a valve body, a movable core disposed between the fixed core and the valve seat, a resilient biasing member for biasing the movable core in a valve-closing direction and a coil. When energized, the coil generates an attracting force between the movable core and the fixed core against a biasing force by the resilient biasing member to cause the movable core to retreat from an initial position where the valve seat 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 and the movable core provides an inclination A (N/mm) at the initial position, the compression resiliency coefficient of the resilient biasing member is set to A (N/mm).Type: GrantFiled: July 9, 2004Date of Patent: July 10, 2007Assignee: Nissan Kogyo Co., Ltd.Inventors: Takaaki Komaba, Takeshi Ohi
