Abstract:
1. A fluid control electromagnetic valve for controlling a flow of fluid, comprising: a fixed core that is formed from metal and is configured to generate electromagnetic attraction force; a movable valving element that includes a movable core formed from metal, wherein the movable valving element is attracted from an initial position to an attraction position as a result of application of the electromagnetic attraction force to the movable core and is returned from the attraction position to the initial position as a result of disappearance of the electromagnetic attraction force, so that the movable valving element reciprocates in its axial direction between the initial position and the attraction position; a resin body that accommodates therein the fixed core and the movable valving element and includes therein a fluid passage through which fluid flows; a valve seat member that is formed from a material having a smaller linear expansion coefficient than the resin body and is accommodated in the resin body, wherein: a first sealing member that is accommodated in the resin body in an elastic compression state to seal the fluid passage and is positioned around the fixed core; and a second sealing member that is accommodated in the resin body in an elastic compression state to seal the fluid passage, wherein:
