Abstract
A moldable central body for use in a catalytic burner has a generally rotational symmetry about a longitudinal axis. It provides a cover retaining surface for the cover of the unit; furnishes the bayonet pin for receiving the cover; carries spacers positioning itself within the outer casing; holds the wave member in position; holds the stem support in position, which, in turn, holds the valve seat; provides a pivot hole for the spoon pivot for a curling iron; is a seat and shoulder for the diaphragm; provides an inner surface to hold alignment members for the control stem; holds the seat for the spring for the control stem; and provides a barrel retaining surface for a curling iron barrel. The control stem of a regulation element moves axially within the central body. The central body can be molded of plastic as a single integral piece. Since this central body serves so many functions and, yet, can be molded as a single integral piece, it reduces the cost of manufacture of the burner of this invention.
