Thermostatic valve assembly

摘要

A thermostatic valve assembly for a cooling system of an internal combustion engine provided with a radiator is provided. The thermostatic valve assembly includes a valve body having an inlet from the radiator, an inlet from the engine and an outlet to the engine. A main valve plate opens and closes the pathway of a cooling fluid from the radiator. A wax element is placed in a chamber of the valve body in fluid communication with the inlets and the outlet. The wax element has a piston mechanically connected to the main valve plate at a distal end. A main spring keeps the main valve plate closed until a target temperature of the cooling fluid coming from the engine is reached. An auxiliary valve plate opens and closes a direct pathway of the cooling fluid from the radiator to the chamber in which the wax element is placed.

1. A thermostatic valve assembly for a cooling system of an internal combustion engine provided with a radiator, the thermostatic valve assembly comprising:
a valve body having an inlet from the radiator, an inlet from the internal combustion engine and an outlet to the internal combustion engine; a main valve plate to open and close a pathway of a cooling fluid from the radiator; a wax element that is held in a chamber of the valve body, wherein the chamber is in fluid communication with the inlets and the outlet, and wherein the wax element has a piston mechanically connected to the main valve plate at a distal end a main spring disposed above an auxiliary valve plate such that the auxiliary valve plate is disposed between the main valve plate and the main spring to keep the main valve plate closed until a target temperature of the cooling fluid coming from the internal combustion engine is reached, wherein the auxiliary valve plate is configured to open and close a direct pathway of the cooling fluid from the radiator to the chamber in which the wax element is held.
