Electronically controlled thermostat |
摘要 |
An electronically controlled thermostat enabling stable valve body actuation, preventing overshooting and hunting, and with reduced size and simplified construction. The thermostat can execute arbitrary variable control of cooling water temperature and includes a thermo-element having a piston actuating opening and closing within a housing of a first valve body and a second valve body to switch the flow path of cooling water by sensing the cooling water temperature and an element guide member holding the thermo-element within the housing. A temperature-sensing chamber is formed by isolation by the element guide member from the flow path in which cooling water on the radiator exit side flows; the temperature-sensing portion of the thermal element is disposed to face this chamber. A linking hole transmits the temperature of cooling water on the radiator exit side from within the flow path to the temperature-sensing portion within the temperature-sensing chamber.
