Abstract

L'invention concerne une soupape électromagnétique, comportant un poussoir de soupape (4) qui est guidé dans un corps de soupape (3, 25) et qui présente un logement de siège de soupape (7, 22) orienté vers l'organe de fermeture de soupape (9). Ce logement forme avec le corps de soupape (3, 25) et le poussoir de soupape (4) un premier sous-module pouvant être actionné de manière indépendante. Cette soupape électromagnétique comprend également un module filtre, ainsi qu'un induit magnétique (14) actionnant le poussoir de soupape (4) pouvant être actionné lui-même par voie électromagnétique au moyen d'une bobine placée sur le corps de soupape (3, 25). Le module filtre forme un deuxième sous-module pouvant être actionné de manière indépendante et contrôlé au préalable. Ce deuxième sous-module présente une soupape antiretour (10) insérée dans un élément filtrant cupuliforme (11). Afin de réduire les coûts de fabrication, l'élément filtrant cupuliforme (11) est réalisé en matière plastique et le corps de soupape (3, 25) est constitué d'une pièce frappée ou extrudée à froid.
