Title
(EN) SOLENOID VALVE ASSEMBLY FOR A COMBUSTIBLE GAS SUPPLY DEVICE TO AN ENDOTHERMIC ENGINE
(FR) BLOC VANNE ELECTROMAGNETIQUE POUR DISPOSITIF D'ALIMENTATION DE MOTEUR ENDOTHERMIQUE EN GAZ COMBUSTIBLE
Abstract
(EN)
The solenoid valve assembly (5) presents an inlet union (8), at least one combustible gas outlet hole (28), and a plate (29) carrying a shutter (13) and operatable by an electromagnet (19) for controlling the solenoid valve (14). The plate (29) is turnable about a contact line (36) of one face (37) engaged by a bar (46) pushed against the plate (29) by a helical compression spring (44), so as to normally keep the shutter (13) in closed position. A valve body (7) is connected to an intermediate plate (12) carrying the outlet holes (28) and is closed by a removable and modular closing plate (9), which carries a variable number of outlet conduits (11). The intermediate plate (12) is provided with a series of grooves (56) adapted to accommodate a series of different gaskets (17), each corresponding to a module of the closing plate (9).
(FR)
Un bloc vanne électromagnétique (5) comporte un raccord d'admission (8), au moins un orifice de sortie de gaz combustible (28), ainsi qu'une plaque (29) portant un volet (13) et actionnée par un électroaimant (19) pour commander la vanne électromagnétique (14). La plaque (29) peut pivoter autour d'une ligne de contact (36) d'une face (37) avec laquelle vient en contact une barre (46) forcée contre la plaque (29) par un ressort de compression hélicoïdal (44), de façon à maintenir généralement le volet (13) en position fermée. Un corps de vanne (7), relié à une plaque intermédiaire (12) comportant les trous de sortie (28), est fermé par une plaque de fermeture amovible et modulaire (9) pourvue d'un nombre variable de conduites de sortie (11). La plaque intermédiaire (12) comporte une série de rainures (56) adaptées pour loger une série de joints différents (17), correspondant chacun à un module de la plaque de fermeture (9).
