Title (EN) DEVICE FOR RELEASING OF PRESSURE IN HYDRAULIC HOSES
(FR) DISPOSITIF DE LIBERATION DE PRESSION DANS DES TUYAUX HYDRAULIQUES
Abstract:
(EN) The present invention comprises in short a device in the form of a tool for unloading pressure in hydraulic systems, said device including tubular housing (2) with a hydraulic liquid collection chamber (5). Preferably at either end of the housing (1) there is a male or female coupling half (17) for connection to a coupling half (20) in a hydraulic system. The coupling half (17) surrounds an actuating member (11), which is axially displaceable in relation to the coupling half (17), from a retracted position to an outward position, in the latter for actuating a valve plunger (21) in the connected coupling half (20) such as to open the valve and release pressure.
(FR) L'invention comprend, brièvement, un dispositif se présentant sous la forme d'un outil permettant de décharger la pression exercée dans des systèmes hydrauliques, ledit dispositif comportant un logement tubulaire (2) doté d'une chambre de collecte de liquide hydraulique (5). De préférence au niveau de chaque extrémité du logement (1) se trouve une moitié d'accouplement mâle ou femelle (17) permettant un accouplement à une moitié d'accouplement (20) se trouvant dans un système hydraulique. La moitié d'accouplement (17) entoure un élément actuateur (11), lequel peut être déplacé axialement par rapport à la moitié d'accouplement (17), d'une position rétractée à une position extérieure, permettant d'actionner dans cette dernière, un plongeur de vanne (21) situé dans la moitié d'accouplement raccordé (20) de manière à ouvrir la vanne et libérer la pression.
