Title (EN) VALVE ARRANGEMENT FOR CONTROLLING AN AIR SUSPENSION, A VALVE UNIT, AND A VEHICLE PROVIDED WITH SUCH DEVICES
(FR) SYSTEME DE SOUPAPES PERMETTANT DE COMMANDER UNE SUSPENSION PNEUMATIQUE, UNITE SOUPAPE ET VEHICULE POURVU DE TELS DISPOSITIFS
Abstract: front page image
(EN)Valve arrangement for multi-axle vehicles having air suspension, which vehicle is provided with at least one axle (1, 2, 3) having two or more air suspension elements (4, 5, 6, 7, 8, 9, 30) which can be pressurised by means of a source of compressed air (10), valves (13, 14, 15, 16, 17, 18) for pressurising or venting said air suspension elements, and a control unit (25) for controlling opening and closing of said valves. The invention also relates to a valve unit provided for each air suspension element, which valve unit comprises a first valve (15a, 16a, 44) between the source of compressed air (10) and the air suspension element (4, 5, 6, 7, 8, 9, 30), for pressurising said air suspension element, and a second valve (15b, 16b, 49) connected between the first valve and the air suspension element, for venting said air suspension element, which valves are normally closed. The invention further relates to a valve unit for said valve arrangement and a vehicle provided with such a valve arrangement.
(FR)L'invention concerne un système de soupapes destiné à des véhicules à essieux multiples pourvus de suspensions pneumatiques. Ce véhicule comprend au moins un essieu (1, 2, 3) ayant au moins deux éléments suspension pneumatique (4, 5, 6, 7, 8, 9, 30) qui peuvent être mis sous pression à l'aide d'une source d'air comprimé (10) ; des soupapes (13, 14, 15, 16, 17, 18) destinées à la mise sous pression ou à l'évacuation d'air de ces éléments suspension pneumatique, et une unité de commande (25) permettant de commander l'ouverture et la fermeture de ces soupapes. L'invention concerne également une unité soupape (13-18) destinée à chaque élément suspension pneumatique, ladite unité soupape comprenant une première soupape (15a, 16a, 44) située entre la source d'air comprimé (10) et l'élément suspension pneumatique (4, 5 , 6, 7, 8, 9, 30) pour la mise sous pression de cet élément suspension pneumatique, et une deuxième soupape (15b, 16b, 49) montée entre la première soupape et l'élément suspension pneumatique, pour l'évacuation d'air de cet élément suspension pneumatique, ces soupapes étant normalement fermées. L'invention concerne enfin une unité soupape de ce système soupapes et un véhicule équipé d'un tel système.
