  • Patent number: 10677118
    Abstract: A thermo actuator includes an actuator body and a large-diameter portion (54) that projects from the actuator body outward in the radial direction. The outer diameter of a return spring is smaller than the inner diameter of a case. The outer diameter of the actuator body and the outer diameter of a valve body are smaller than the inner diameter of the return spring. The outer diameter of the large-diameter portion is smaller than the inner diameter of the case and is larger than the average diameter of the return spring. One end of the return spring is in contact with the large-diameter portion.

  • Patent number: 10288177
    Abstract: A method of manufacturing a thermo valve includes an overlaying step of overlaying a valve body onto a thermo actuator so as to cover a groove portion; and a caulking step of caulking an installing portion of the valve body onto the thermo actuator. The caulking step is performed by pressing, by use of a jig, the valve body and the thermo actuator toward an axis center in a radial direction. A pressing face of the jig has a short side portion and a long side portion longer than the short side portion. Pressing is performed with the long side portion being substantially in parallel to the axis center of the thermo actuator and the short side portion being substantially in parallel to the groove portion.
