Abstract: A solenoid operated valve of the type intended to be operated with a constant frequency variable duty cycle electrical pulse signal. The valving member/armature has an elastomeric cap provided on one end which functions to close one face on a valve seat when the solenoid is de-energized and the opposite face functions to act as a limit stop for valving member movement in the opposite direction when the solenoid is energized.

Abstract: An ignition apparatus for a gaseous fuel burner having two areas of gaseous fuel discharge comprises a primary electrode positioned within a first area of gaseous fuel discharge and a secondary electrode having a first end positioned within the first area in close proximity to the primary electrode defining a jump gap, and a second end within a second area in proximity to the burner to form a ground spark gap. The burner has an outer and an inner periphery ignition area forming a torres shaped, or donut-like, burner separated by a gaseous fuel plenum through which the secondary electrode penetrates. The primary electrode may be mounted within the inner or outer periphery ignition area.

Abstract: A surface gas burner assembly for a gas range comprises a circular burner base having a gas inlet portion, a gas plenum portion, and a gas port portion. The gas port portion comprises a raised wall around an outer periphery of the base having a top surface. A wave washer port ring having an upper surface and a lower surface is also included. This upper surface comprises a upper mounting surfaces defining a plurality of upper gas port channels. The lower surface comprises lower mounting surfaces also defining a plurality of lower gas port channels. A circular burner cap has a raised wall around its outer periphery which includes a bottom surface. The lower mounting surfaces of the wave washer port ring are positioned on upper surface of the first raised wall to form a gas ports in conjunction with the plurality of lower gas port channels.
