Title (EN) HYDRAULIC RESERVOIR PRESSURE RELIEF MECHANISM
(FR) MÉCANISME DE DÉCOMPRESSION POUR RÉSERVOIR HYDRAULIQUE
Abstract:
(EN) An exemplary hydraulic reservoir includes a reservoir tank having an interior cavity for retaining a fluid and an aperture fluidly connecting the interior cavity to an exterior region of the reservoir. A cover selectively engages the reservoir tank, and is movable between an open position, wherein the fluid path through the aperture in the reservoir tank is at least partially open, and a closed position, wherein the fluid path through the aperture is substantially closed. The hydraulic reservoir further includes a pressure relief mechanism having at least one pressure responsive fastener for releasably connecting the cover to the reservoir tank. The at least one pressure responsive fastener includes a fastener fixed for concurrent movement with one of the cover and the reservoir tank, and a biasing member operably connecting the fastener to whichever of the cover and reservoir tank is not fixed for concurrent movement with the fastener.
(FR) La présente invention concerne typiquement un réservoir hydraulique comprenant une cuve réservoir définissant une cavité interne servant à retenir un fluide, et une ouverture reliant fluidiquement à une zone externe du réservoir la cavité interne. Un couvercle qui s'applique sélectivement sur la cuve réservoir, est mobile entre une position ouverte et une position fermée. En position ouverte, le chemin du fluide au travers de l'ouverture de la cuve réservoir est au moins en partie ouvert. En position fermée, le chemin du fluide au travers de l'ouverture est sensiblement fermé. Le réservoir hydraulique comporte également un mécanisme de décompression équipé d'au moins moyen de retenue réagissant à la pression de façon à relier de façon interruptible le couvercle à la cuve réservoir. Ledit moyen de retenue réagissant à la pression comporte, d'une part un élément de fixation maintenu de façon à pouvoir se déplacer en même temps que le couvercle ou la cuve réservoir, et d'autre part, un élément à charge de ressort reliant fonctionnellement l'élément de fixation à celui du couvercle ou de la cuve réservoir auquel il n'est pas maintenu de façon à en permettre le déplacement en même temps que l'élément de fixation.
