2. Prior Art Statement
It is known to provide a fuel control valve construction comprising a housing means having an inlet means adapted to be interconnected to a fuel source and a main outlet means adapted to be interconnected to a main burner means, the housing means having a pilot outlet means adapted to be interconnected to a pilot burner means for the main burner means, the housing means having a pilot valve seat and a main valve seat for interconnecting the inlet means respectively with the pilot outlet means and the main outlet means, the housing means having a movable pilot valve member for opening and closing the pilot valve seat and a movable main valve member for opening and closing the main valve seat. For example, see the U.S. patent to Kelly, U.S. Pat. No. 4,549,571.
It is also known to provide a combination comprising a supporting means, electrically operated coil means carried by the supporting means, and two movable plunger means carried by the supporting means and being operatively associated with the coil means to be moved to certain positions thereof when the coil means is energized. For example, see the aforementioned patent to Kelly, U.S. Pat. No. 4,549,571.
