Abstract

Disclosed are a thermo bypass valve and a method for detecting a failure of the thermo bypass valve. The thermo bypass valve is configured to include a valve body configured to make an outlet passage and a bypass passage communicate with an inlet passage within an inner space of the valve body, a piston assembly disposed in the inner space of the valve body and have a thermal expansion material received in the piston assembly, and an elastic member disposed between the piston assembly and an inner surface of the valve body. Thus, the thermo bypass valve and the method of the present invention are capable of radically preventing oil from overheating at the time of the failure of a valve due to the leak of the thermal expansion material.

First claim

What is claimed is:

1. A thermo bypass valve, comprising:
a valve body configured to make an outlet passage and a bypass passage communicate with an inlet passage within an inner space thereof so that a fluid introduced from an outside is selectively discharged or bypassed via the inner space thereof;
a piston assembly disposed in the inner space of the valve body and have a thermal expansion material received therein to make the inlet passage selectively communicate with the ou…
