Patent attributes
A hydraulic energy absorption device including a cylindrical housing having an interior hollow compartment, the interior hollow compartment having a distal end and a proximal end, a resilient member arranged within the distal end of the cylindrical housing, a piston arranged adjacent to the resilient member within the cylindrical housing, the piston including a piston head and a piston rod extending from the piston head toward the proximal end and a compressible accumulator arranged within the cylindrical housing and connected to the piston. When the piston rod is displaced toward the distal end of the cylindrical housing in operation, the piston head and the compressible accumulator are displaced toward the distal end of the cylindrical housing.
