  • Patent number: 10622144
    Abstract: A method for producing a pair of electrically conductive members assembled into an electrical component assembly provided with a coil. The method includes: forming connection terminal sections provided in the pair of electrically conductive members by arranging them alternately opposite to each other and then performing press punching; and after the press punching, bending the connection terminal sections in the pair of electrically conductive members toward a side departing from the coil into a protruding form.

  • Publication number: 20170084391
    Abstract: A connection structure for electrical component assembly including: an electrical component assembly provided with a coil energized through a pair of electrically conductive members; and a housing that covers the electrical component assembly and that is provided with housing-side connection terminals. The electrically conductive member has a connection terminal section connectable to the housing-side connection terminal. The connection terminal section is bent toward a side departing from the coil so as to protrude toward a side of the electrical component assembly, and one of the connection terminal sections is arranged at a position deviated in an axis direction of the coil relative to the other of the connection terminal sections.

  • Patent number: 6755390
    Abstract: An electromagnetic valve has a cylindrical-shaped valve housing, a fixing core; a movable core; a first return spring; a coil; a first valve mechanism including a movable seat member, a second return spring, a first valve part, a first valve seat, and a first valve hole, and a second valve mechanism including a cylindrical-shaped valve seat member, a second valve seat, a second valve hole, and a second valve part, wherein, on the movable seat member, a cylindrical-shaped guide part, when the second valve part is seated on the second valve seat, is cut off from the valve chamber but, when the second valve part is separated from the second valve seat, forms an annular-shaped passage communicating with the valve chamber and is slidably fitted into the second valve hole; and a communication passage for allowing the annular-shaped passage to communicate with the interior of the guide part is formed.
