Patent

CA 2257134

The invention relates to a valve device (1), comprising a valve housing with at least one inlet channel (6) and an outlet channel (7), a valve piston (5) which can be moved axially in the valve housing and has control edges (14, 15, 16), for releasing and blocking the connection between the cross-sections of the inlet (6) and outlet (7) channels, and a regulating device (2) for applying the actuating force to the valve piston (5). The invention is characterized in that it provides elements (21) for producing a force opposing the actuating force through at least a part (a proportional area) of the overall working range of the valve device, depending on the pressure in the outlet channel (7).

L'invention concerne un dispositif à soupape (1) comprenant un carter de soupape avec au moins une voie d'arrivée (6) et une voie de sortie (7), un piston de soupape (5) se déplaçant axialement dans le carter de soupape et présentant des arêtes de commande (14, 15, 16) pour libérer et bloquer la jonction des sections des voies d'arrivée (6) et de sortie (7), un dispositif de réglage (2) pour la mise sous pression du piston de soupape (5) avec une force d'actionnement. L'invention se caractérise en ceci que des éléments (21) génèrent une force opposée à la force d'actionnement sur au moins une partie (zone proportionnelle) de la zone de travail totale du dispositif à soupape, en fonction de la pression dans la voie de sortie.
