Abstract:
A fluid control electromagnetic valve includes a fixed core, a movable valving element, a resin body, a valve seat member, a first sealing member, and a second sealing member. The valve seat member is formed from a material having a smaller linear expansion coefficient than the resin body. The first sealing member is accommodated in the resin body in an elastic compression state to seal a fluid passage and is positioned around the fixed core. The second sealing member is accommodated in the resin body in an elastic compression state to seal the fluid passage. The valve seat member is clamped between the second sealing member and the first sealing member in an axial direction. Elastic restoring force applied by the second sealing member to the valve seat member is larger than elastic restoring force applied by the first sealing member to the valve seat member.
