Abstract:
1. A temperature sensitive fluid flow control valve configured for installation between a fluid supply and a fluid cooler, the control valve comprising: a cap having a closed first end including an axially disposed post and a shoulder coaxial with said post and supported from said cap; an actuator including an actuator body, a guide extending from said actuator body to a first end of said actuator and an oppositely directed plunger extending from said actuator body to a second end of said actuator, said guide defining an axial bore open at said first end and including a first flange projecting radially outwardly from said first end, said actuator body radially outward of said guide forming a metering surface; a retainer secured to said shoulder to form (1) a second flange facing said cap closed first end and (2) a valve seat on an opposite side of said retainer, said retainer defining a central flow aperture through which said actuator guide is received with said post extending into said guide axial bore; a first bias member engaged between said first and second flanges to bias said actuator toward a first position where said metering surface is against said valve seat and said actuator body and guide close said central flow aperture; a valve member movably secured to said plunger and surrounding said second end of said actuator, said valve member axially movable with respect to said plunger and biased away from said actuator body toward an extended position; wherein said actuator exerts a force F on said post at temperatures above a predetermined temperature T, said force F sufficient to overcome the bias of said first bias member and move the metering surface of said actuator body away from said valve seat to open a flow path around said guide and through said flow aperture.
