Patent ·
OSTI ID:6626010

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; control valve means carried by the housing means for connecting the inlet means to the outlet means when the control valve means is in an open condition thereof; and passage defining means carried by the housing means and leading from the inlet means to the control valve means. The improvement described here is wherein the passage defining means has means that is adapted to cause the fuel to serially flow through a first substantially U-shaped path and a second substantially U-shaped path and a third substantially U-shaped path between the inlet means and the control valve means. The first and third U-shaped paths each normally face substantially vertically upwardly and the second U-shaped path normally faces substantially vertically downwardly and is disposed between the first and second U-shaped paths. The means of the passage defining means causes the first U-shaped path to have a yoke portion and a pair of legs respectively connected to the ends of the yoke portion.
