ABSTRACT:
A condition responsive by-pass valve construction having a housing provided with an inlet and two outlets interconnected to the inlet, the housing having a valve seat disposed between one of the outlets and the inlet. The housing carries a movable valve member for controlling the valve seat to provide substantially a linear percentage by-pass flow between the inlet and the one outlet as the valve member moves between a fully opened position thereof and a fully closed position thereof. The housing carries a condtion responsive device for controlling movement of the valve member. One of the valve seat and the valve member has tapered groove means for progressively bridging and unbridging the other of the valve seat and valve member to provide the substantially linear percentage by-pass flow.
