Burner control device, system and method of making the same
This patent describes a control device for supplying fuel to a burner means, the device comprising a housing means having an inlet means for being interconnected to a source of fuel and having an outlet means for being interconnected to the burner means, and first and second control valve means carried by the housing means and being in series to connect the inlet means to the outlet means only when both of the control valve means are in an open condition thereof. Each control valve means comprises a movable valve member resiliently biased closed and an independent electromagnetic valve member latching means energizable to hold its respective valve member open and deenergizable to allow its respective valve member to close. Each control valve means has movable means to open its respective valve member to a latching position so as to be held open by its respective latching means when its respective latching means is energized. The improvement described here comprises a single manually movable actuator means carried by the housing means and a push button-like member. A means operatively interconnects the movable means together and is operatively associated with the push button-like member so that the valve members will move substantially in unison to their latching positions as the actuator means is moved to an actuated position thereof.
