Abstract

L'invention concerne une vanne électromagnétique pulsatrice bistable comprenant : un noyau de vanne (1), une bobine à impulsions (2), un logement supérieur (3), le premier logement inférieur (4), le deuxième logement inférieur (5), et une vanne (6) avec des orifices d'admission de pression (61) et des orifices de sortie de pression (62). La bobine à impulsions (2) est située à l'extérieur du logement supérieur (3). L'espace entre le premier logement inférieur (4) et le deuxième logement inférieur (5) peut être raccordé à ou déconnecté de l'espace dans le deuxième logement inférieur (5) grâce au mouvement rotatif du noyau de la vanne (1) par rapport à la vanne (6) dans le logement supérieur (3). Le noyau de vanne (1) est un noyau magnétique permanent. La vanne électromagnétique pulsatrice bistable comprend de plus un support en fer (7) qui est placé près de la bobine à impulsions (2) afin de positionner le mouvement du noyau de vanne (1). La longueur du noyau de vanne (1) est supérieure à la distance entre le support en fer (7) et la vanne (6). La vanne électromagnétique pulsatrice bistable consomme peu d'énergie, comporte moins de pièces internes, est facile à fabriquer en série et est très fiable, ce qui élimine les inconvénients des vannes électromagnétiques pulsatrices bistables actuelles qui ont plus de pièces internes et dont la fabrication est complexe.
