Abstract
A control valve for a resonant burner having a burner space for receiving active substance through a conduit with an atomizing nozzle discharging into the space is disclosed. When the valve is shut off to terminate flow of the active substance through the valve to the burner conduit, a spring action in the valve tends to withdraw the active substance from the conduit by creating a suction effect therein.
