  • Patent number: 9217358
    Abstract: A thermostat device useful in a cooling system circulating liquid coolant has a valve, a cylindrical valve seat having an inner peripheral surface, and a circular sealing lip elastically pressure welded to the inner peripheral surface when the valve is closed, the sealing lip forming a waveform having concavity and convexity curving in the valve drive direction due to a thermo-sensitive movable body, allowing displacement of the contact position of the sealing lip with the inner peripheral surface when the valve is closed in the valve drive direction according to the position in the circumferential direction of the circular sealing lip, which device stabilizes system operation during initial valve opening, and which device stabilizes the liquid coolant temperature.

  • Publication number: 20130126624
    Abstract: Disclosed is a thermostat device which can both stabilise operation during the initial stages of valve opening, and can stabilise the temperature of a liquid coolant which is circulated in a cooling system circuit. A circular sealing lip (29) is provided on the outer periphery of an approach section (24) of a main valve (21), said approach section being to a cylindrical valve seat (11), and the circular sealing lip is elastically pressure welded to the inner peripheral surface of the cylindrical valve seat (11) when the valve is closed. The circular sealing lip (29) is provided so as to form a waveform having concavity and convexity curving in the drive direction of the main valve (21), due to a thermo-sensitive movable body (31).

  • Patent number: 8186604
    Abstract: An apparatus includes a movable temperature sensing member capable of sensing mainly the temperature of high-temperature coolant flowing in from a high-temperature coolant port and driving toward the side of the high-temperature coolant port in dependence upon the sensed temperature; a main valve fitted integrally to the movable temperature sensing member and constructed so as to render a low-temperature coolant port and a mixing compartment openable in conformity to the driving of the movable temperature sensing member toward the side of the high-temperature coolant port, thereby controlling the inflow rate of low-temperature coolant from the low-temperature coolant port to the mixing compartment; and a high-temperature coolant inducing part communicating with the high-temperature coolant port and adapted to regulate the flow of high-temperature coolant from the high-temperature coolant port toward the surround of the movable temperature sensing member and effect outflow thereof to the mixing compartment.

  • Patent number: 8029188
    Abstract: A temperature sensor for an automobile is disclosed. The temperature sensor includes a conductive sensor body including a bottom wall, an insulative connector housing coupled to the sensor body, first and second terminals provided inside the connector housing, which have lower contact portions, a ceramic element mounted near the bottom wall in the sensor body for detecting temperature, which has lower and upper electrode surfaces, and a connecting disc mounted on the ceramic element, which has lower and upper connecting surfaces. The lower electrode surface of the ceramic element is attached to the bottom wall by a conductive adhesive layer and grounded to the sensor body. The upper electrode surface of the ceramic element is electrically connected to the lower contact portion of the first terminal through the lower and upper connecting surfaces of the connecting disc. The lower contact portion of the second terminal contacts the sensor body.
