Abstract

Le bloc de distribution comporte une plaque de base (1) munie de canaux longitudinaux (11 à 15) pour l'air amené et l'air sortant, des canaux d'air de travail (16, 17) situés transversalement aux précédents, des canaux de raccordement (21 à 27) qui débouchent dans un gabarit de perçage déterminé dans le côté de raccordement (18), ainsi qu'un canal en forme de puits (19) pour une installation électrique (20). Du côté (18) de la plaque de base destiné au raccordement, il est prévu au moins une unité comprenant un distributeur (2) et deux soupapes de présélection (3, 4) qui commandent ledit distributeur (2). Les soupapes de présélection (3, 4) sont placées dans un carter (41) fixé par une surface de montage sur une face frontale (43) du distributeur (2). Un socle à fiches qui déborde de la partie inférieure (20) du carter de soupapes (41) s'engage dans le canal en forme de puits (19) en passant à travers un passage (97) pratiqué dans la plaque de base et comporte des lamelles de contact (93, 94) qui sont en saillie et qui sont raccordées à des pinces de contact (95, 96) situées sur la carte de circuits (20). Afin de minimiser les tolérances de montage, une pièce (101) sous forme de plaque se trouve à l'extrémité inférieure du carter de soupapes (41) et déborde latéralement entre le distributeur (2) et la plaque de base (1). Cette pièce en saillie (101) comporte des alésages de passage (102 à 107) correspondant au gabarit de perçage de la plaque de base (1).
