Abstract

First and second cylindrical chambers in line with each other are contained in a housing, and the first one is filled by a bellows, forming with the chamber a fluid container in all positions, connected by passages to the hydraulic system. The second chamber contains a compression spring acting via a component on the bellows and tending to expand it. A stop limits the amount of expansion, and an adjustment is provided for the amount of compression or the spring, typically in the form of a rod screwing into the end of the second chamber, and equipped with a hand grip. The component can include a sleeve, bearing against bellows and spring.
