Abstract: The pneumatic oscillating valve includes a housing defining an internal chamber, an inlet passageway, and an outlet passageway. An annular seat extends into the internal chamber. A diaphragm is disposed in the internal chamber. The diaphragm seats against the annular seat and separates the inlet passageway from the outlet passageway. A spring engages the diaphragm to seat the diaphragm against the annular seat. As fluid is admitted to the inlet passageway, pressure increases in the inlet passageway until sufficient pressure is present to overcome the spring and unseat the diaphragm. The inlet passageway is more restrictive to fluid flow than the outlet passageway such that fluid is exhausted more quickly from the outlet passageway than can pass through the inlet passageway allowing pressure in the inlet passageway to reduce to a point less than the spring force of the spring thereby allowing the diaphragm to reseat on the seat.

An alarm can also be configured to sound when the grill is attempted to be ignited with the cover closed, thereby avoiding a potential explosion. A biasing attraction magnet is incorporated in the fluid flow switch to offset either the force of gravity or a return spring in order to extend performance to low pressure and low flow applications.
