ABSTRACT:
An adjustable energy absorber including a housing having a ram slidably extending therefrom. A first control sleeve divides the housing into a pair of fluid chambers, which sleeve has an axially extending row of openings to provide communication between the two chambers. A second control sleeve surrounds the first sleeve and is nonrotatably connected thereto. The first and second sleeves have compatible outer and inner conical surfaces, respectively. The first and second sleeves are axially adjustable with respect to one another to form a narrow flow passage between the opposed conical surfaces. Imposition of a force on the ram causes fluid to be forced from one chamber through the openings into the flow passage, and then into the other chamber. By varying the width of the flow passage, as by axially moving one control sleeve relative to the other, the amount of energy absorbed by the fluid during the movement of the ram can be selectably adjusted.
