Title (EN) DEVICE FOR ADJUSTABLE PRESSURE CONTROL BETWEEN TWO SERVICE PRESSURES FOR AN OIL/HYDRAULIC PRESSURE LINE
(FR) DISPOSITIF RÉGULATEUR DE PRESSION RÉGLABLE ENTRE DEUX PRESSIONS DE SERVICE POUR UNE CONDUITE DE PRESSION OLÉO-HYDRAULIQUE
(PT) DISPOSITIVO CONTROLADOR DE PRESSÃO REGULÁVEL ENTRE DUAS PRESSÕES DE SERVIÇO PARA UMA LINHA DE PRESSÃO ÓLEO-HIDRÁULICA
Abstract:
(EN) Device, for opening and closing an oil/hydraulic pressure line, for adjustable pressure control between two service pressures, via a pneumatic inlet, which comprises: a body for coupling the device to the pressure line; a positioning shaft; a seal mounted so as to move longitudinally along the positioning shaft, in order to close the pressure line; a piston mounted so as to move along the interior of said body; a compression spring mounted between said seal and said piston, in order to exert pressure on the seal; a pneumatic inlet for exerting pressure on said piston with a view to closing the pressure line; an adjustable nut for adjusting said first position of the piston so as to refine the first pressure. The body may have a screw thread and be configured so that the distance between said body and the pressure line is adjustable in order to adjust said second position of the piston so as to refine the second pressure.
(FR) L'invention concerne un dispositif régulateur de pression destiné à ouvrir et fermer une conduite de pression oléo-hydraulique, réglable entre deux pression de service, au moyen d’une entrée pneumatique, comprenant : un corps pour accoupler le dispositif à la conduite de pression ; un tube de positionnement ; un élément d’étanchéité monté de manière à se déplacer longitudinalement le long du tube de positionnement, en vue de fermer la conduite de pression ; un piston monté de manière à se déplacer le long de l'intérieur dudit corps ; un ressort de pression monté entre ledit élément d’étanchéité et ledit piston, pour appliquer une pression sur l’élément d’étanchéité ; un entrée pneumatique pour appliquer une pression sur ledit piston dans le sens de fermeture de la conduite de pression ; une tige réglable pour ajuster ladite première position du piston de manière à affiner la première pression. Le corps peut être fileté et conçu de sorte que la distance entre ledit corps et la conduite de pression soit réglable pour ajuster ladite seconde position du piston de manière à affiner la seconde pression.
(PT) Dispositivo controlador de pressão para abrir e fechar uma linha de pressão óleo- hidráulica, regulável entre duas pressões de serviço, através de uma entrada pneumática, que compreende: um corpo para acoplar o dispositivo à linha de pressão; um veio posicionador; um vedante montado para se mover longitudinalmente ao longo do veio posicionador, para fechar a linha de pressão; um êmbolo montado para se mover ao longo do interior do referido corpo; uma mola de pressão montada entre o referido vedante e o referido êmbolo, para exercer pressão sobre o vedante; uma entrada pneumática para exercer pressão sobre o referido êmbolo no sentido de fechar a linha de pressão; um perno ajustável para ajustar a referida primeira posição do êmbolo de forma a afinar a primeira pressão. O corpo pode ser roscado e configurado para que distância entre o referido corpo e a linha de pressão seja ajustável para ajustar a referida segunda posição do êmbolo de forma a afinar a segunda pressão.
