Abstract

L'invention concerne une installation d'alimentation en air comprimé (1.1) d'un véhicule, comprenant un compresseur (2) commandé par pression, au moyen duquel de l'air comprimé peut être refoulé dans un mode de refoulement dans une conduite de pression principale (12) en passant par une conduite de refoulement (6) et une conduite de séchage (7), au moins une unité de séchage (9) ainsi qu'un clapet anti-retour (10) monté en aval de cette unité de séchage (9) étant agencés dans la conduite de séchage, et une soupape d'aération (4) commandée par pression, au moyen de laquelle la conduite de séchage peut être reliée à une sortie d'aération (16) pour un mode de régénération, ainsi qu'une soupape de régénération (17) commandée par pression, permettant de mettre le compresseur (2) à l'arrêt et/ou d'ouvrir la soupape d'aération (4), et une soupape de commande de compresseur (22) réalisée sous la forme d'une soupape électromagnétique pour la mise à l'arrêt électronique du compresseur (2). L'invention vise, dans le mode de régénération, à réaliser une régénération plus intensive et plus rapide de l'unité de séchage (9). Un étranglement (26) est à cet effet monté en parallèle par rapport au clapet anti-retour (10) dans la conduite de séchage (7) pour le prélèvement direct d'air de balayage de la conduite de pression principale (12), étranglement dont la section transversale est dimensionnée de telle manière qu'un débit volumique d'air de balayage relativement important se forme certes dans le mode de régénération, mais que la chute de pression provoquée par l'évacuation de l'air de balayage dans la conduite de pression principale est limitée à une valeur de pression rendant possible un fonctionnement des dispositifs alimentés par la conduite de pression principale.
