ENGINE TEMPERATURE CONTROLLER

摘要

An engine temperature controller includes a valve body, a worm gear shaft (17) assembled on the valve body, a temperature control executing mechanism for controlling a large and a small coolant circulation loops and an automatic control loop for the large and the small coolant circulation loops which mainly consists of a micro-computer control mechanism (35). By utilizing I-type temperature control executing mechanism directly driven by the worm gear shaft (17) or II-type temperature control executing mechanism driven by the worm gear shaft (17) and a rack shaft (27) engaged with the gear (28) thereon, the large and the small coolant circulation loops are controlled respectively. The engine temperature controller is reasonable in structure, accurate and reliable in control and able to keep the engine at the optimal working temperature state when running in any climate environment, so as to improve the running performance of the engine and prolong the service life of the engine.
