Title
(EN) TRAVELING SPARK IGNITER
(FR) ALLUMEUR À ÉTINCELLE CIRCULANTE
Abstract
(EN)
An igniter having at least two electrodes spaced from each other by an insulating member having a substantially continuous surface along a path between the electrodes. The electrodes extend substantially parallel to each other for a distance both above and below said surface. The insulating member has a channel (recess) for receiving at least a portion of a length of at least one of said electrodes below and to said surface of the insulating member. The surface of the insulating member may preferably be augmented with a conductivity enhancing agent. The insulating member and electrodes are configured so that an electric field between the electrodes at said surface does not have abrupt field intensity changes, whereby when a potential is applied to the electrodes sufficient to cause breakdown to occur between the electrodes, discharge occurs at said surface of the insulating member to define a plasma initiation region.

L'invention concerne un allumeur doté d'au moins deux électrodes séparées l'une de l'autre par un élément isolant présentant une surface sensiblement continue le long d'un chemin entre les électrodes. Les électrodes s'étendent sensiblement parallèlement l'une à l'autre sur une certaine distance, aussi bien au-dessus qu'au-dessous de ladite surface. L'élément isolant comporte une rainure (évidement) servant à recevoir au moins une partie de la longueur d'au moins une desdites électrodes au-dessous et à ladite surface de l'élément isolant. La surface de l'élément isolant peut de préférence être enrichie d'un agent renforçant la conductivité. L'élément isolant et les électrodes sont configurés de telle façon qu'un champ électrique entre les électrodes au niveau de ladite surface ne présente pas de variations soudaines d'intensité du champ, de sorte que, lorsqu'un potentiel appliqué aux électrodes est suffisant pour provoquer un claquage entre les électrodes, une décharge se produit au niveau de ladite surface de l'élément isolant pour définir une région d'amorçage de plasma.
