Claims
- 1. A thermostatically controlled valve which comprises:
- (a) an elongated body having an internal chamber and an inlet port and an outlet port opening into said chamber;
- (b) first and second valve port means disposed in said chamber;
- (c) valve means disposed in said chamber and axially movable to and from said first and second valve port means so as to adjust flow rate therethrough;
- (d) spring means disposed in said chamber and biasing said valve means toward a valve closed position with respect to said second valve port means;
- (e) means in said second valve port means for providing a desired continuous fluid communication through said second valve port means; and
- (f) a temperature-responsive axial force actuator connected to and forming a part of said valve means,
- increasing temperature causing expansion of said actuator to move said valve means against the biasing action of said spring means, thereby increasing the flow rate through said second valve port means and reducing the flow rate through said first valve port means and hence through said outlet port over at least a portion of the path of said valve means.
