Abstract

L'invention concerne un dispositif de régulation de la pression dans les chambres d'un vérin hydraulique comportant un siège (5) de clapet creux s'étendant sensiblement longitudinalement entre deux portions d'extrémité, le corps du siège (5) de clapet étant connecté à une source de fluide pressurisé (18), chacune des portions d'extrémités du siège (5) de clapet étant reliée à une chambre du vérin hydraulique et adaptée pour accueillir un clapet (7a,7b) permettant de contrôler la réalimentation en fluide hydraulique de ladite chambre du vérin, caractérisé en ce qu'un ressort (6) de rappel de clapet est disposé dans ledit siège (5) de clapet et en ce que chacune des extrémités dudit ressort de rappel de clapet est accrochée à un desdits clapets (7a,7b).

Figure 00000001
The invention relates to a device for regulating the pressure in the chambers of a hydraulic cylinder comprising a hollow valve seat (5) extending substantially longitudinally between two end portions, the body of the valve seat (5) being connected to a source of pressurized fluid (18), each of the end portions of the valve seat (5) being connected to a chamber of the hydraulic cylinder and adapted to accommodate a valve (7a, 7b) for controlling the replenishment of fluid hydraulic of said cylinder chamber, characterized in that a valve return spring (6) is arranged in said valve seat (5) and in that each of the ends of said valve return spring is hooked to one of said valves (7a, 7b).
