Abstract:
1. An electronically controlled thermostat, comprising: a housing having a first sleeve configured to receive a coolant from an engine, a second sleeve configured to receive the coolant from a radiator, a first flow path configured to outflow the coolant from the radiator to the engine, and a second flow path configured to outflow the coolant from the first sleeve to the engine; a first valve positioned to open and close the first flow path; a second valve positioned to open and close a third flow path from the engine; a shaft configured to support the first and second valves; an element guide member including at least one hole mounted inside of the housing; and a thermo-element including a piston connected to the shaft and a temperature-sensing portion held by the element guide member so that the temperature-sensing portion is positioned in the first sleeve, said thermo-element configured to sense a temperature of the coolant and to retract and extend the piston based on the sensed temperature of the coolant to control an opening and closing of the first and second valves, wherein the element guide member is formed from material with excellent heat conduction properties.
