Title:
DEVICES FOR HIGH VOLTAGE IGNITION OF COMBUSTIBLE GAS
Document Type and Number:
WIPO Patent Application WO2006044866
Kind Code:
B1
Abstract:
High voltage gas igniters are described, including a hand held portable gas torch igniter of the piezoelectric-type which includes a finger grip housing body actuated by inward depression of the push button igniter to generate a spark-producing voltage when held near the combustible gas exiting the bum tube of a torch or combustible gas exit of a heating device. The igniter has a tube electrode for easy construction, and deflector shield for user protection and gas mixing. Other igniters have multiple spark gaps for increased effective spark length.
