Abstract
The present invention relates to a hydropneumatic shock absorber. This new telescopic system comprises an outer sliding tube, an inner sliding tube having an adjustable braking level of the shock absorber in expansion. Fastened on the base of the outer sliding tube is the bottom of a barrel on which rests counter-acting spring, or other elastic device, which pushes on the inner sliding tube in the expansion stroke. The inner sliding tube carries at its internal end a bell which cooperates with a stop spring when in the expansion stroke. The liquid filled barrel contains an axially movable piston connected to the closure plug assembly of the inner sliding tube by a support tube. The piston contains a first valve, which opens only in the compression phase, and a second valve, which acts as variable throttle and is controlled by the padded end of a screw axially placed within the support tube. The screw axially traverses the support tube and protrudes from the closure plug assembly of the inner sliding tube so that it can be actuated. By acting on this screw, the expansion braking level of the shock absorber can be adjusted.
