Abstract
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.
