Abstract

This nozzle (2) has a central core (9) which is surrounded by a tubular envelope (8), these two pieces being electrically conductive and insulated from one another and defining a passage for a mixture capable of burning with oxygen, the passage extending up to a central conduit of the outlet (39) of the nozzle and defining, at least locally, an air gap for spark discharge. The air gap is arranged annularly and in the inside of the nozzle at a certain distance from the outlet (39) downstream of this air gap, the cross-section of the passage for the mixture capable of burning with oxygen is virtually constant. Application to the piezoelectric ignition modules for burners for combustion with oxygen.
