A recoil-counter-recoil energy absorber unit including an outer housing for guiding a recoiling mass, an hydraulic energy absorber unit mounted between a portion of the housing and the mass, a recoil spring mounted between the energy absorber unit and the housing, a second housing mounting the hydraulic energy absorber unit and for permitting it to move unrestrictedly in a recoil direction but resisting movement thereof in a counter-recoil direction, whereby the second housing will be stretched after the hydraulic energy absorber moves beyond a predetermined counter-recoil position to thereby absorb counter-recoil energy as a result of being stretched. Included in the hydraulic energy absorber is an improved bottoming stop and combined bottoming energy absorber, guidance member, and accumulator retainer which consists of an annular channel member having an inner portion slidably mounted on the piston rod of the hydraulic energy absorber and has a second portion slidably supporting the cylinder of the hydraulic energy absorber, with a movable bottom closure mounted on the cylinder for compressing the annular channel member when the hydraulic cylinder bottoms against a fixed stop attached to the outer housing.
A recoil-counter-recoil system for absorbing energy of a body moving in first and second opposite directions during recoil and counter-recoil, respectively, comprising a base, first energy absorber means mounted relative to said base for absorbing the recoil energy of said body during movement of said body in said first direction toward said base, second energy absorber means mounted on said base, coupling means for coupling said second energy absorber means to said body when said body moves in said second direction, said second energy absorber means comprising an elongated resilient member stretchable in said second direction for absorbing the energy of counter-recoil of said body as a result of being stretched by movement of said body in said second direction.
An energy absorber for absorbing energy comprising a cylinder for containing hydraulic fluid, a piston in said cylinder, a base member, a piston rod mounted on said base member and having first and second end portions, means mounting said first end portion on said base member, means mounting said piston on said second end portion, an end closure on said cylinder between said first and second end portions, a first surface on said end closure facing said base member, a second surface on said end closure facing said piston, means mounting said end closure for movement relative to said cylinder in a direction axially of said piston rod, a third surface on said cylinder between said piston and said end closure, energy absorbing bottoming stop means comprising means for engaging said first surface to cause said end closure to travel toward said piston, and yieldable means in said cylinder for being engaged between said second surface and said third surface for absorbing bottoming impact.
An energy absorber for absorbing energy comprising a cylinder for containing hydraulic fluid, a piston in said cylinder, a piston rod having first and second end portions, means mounting said piston on said first end portion, an end closure between said first and second end portions, means mounting said end closure on said cylinder for movement axially of said piston rod, and energy absorbing bottoming means in said cylinder in abutting relationship to said end closure.
An energy absorber comprising a cylinder, hydraulic fluid within said cylinder, a piston in said cylinder, a piston rod having first and second end portions, means mounting said piston on said first end portion, an end closure on said cylinder between said first and second end portions, yieldable bottoming means within said cylinder and spaced from said piston, a first surface on said end closure facing said piston, a second surface on said yieldable bottoming means facing said first surface, a third surface on said yieldable bottoming means facing said piston, and a fourth surface within said cylinder for abutting said third surface to cause said yieldable bottoming means to be clamped between said first and fourth surfaces for absorbing energy.
