Abstract (en)
[origin: WO9630965A1] A dual action support cylinder placed between a support (2) and a load (1) for applying on said load a nominal force of about 400 to 3900 N for a low displacement of less than 1 cm, characterised in that it has a body (10) forming a vessel connected to said support (2) and closed on both sides by a cover (11, 12), said covers and body defining a housing with two chambers (32, 33), each sealed by a flexible membrane (36, 39). The two covers (11, 12) are connected to each other by connecting means (16) comprising ties (45) arranged through the body (10) and the covers (11, 12). The body (10) has a cylindrical flange (30, 31) placed on either side of a core member (50) and co-operating with a collar (37, 40) for gripping the inner edge of each membrane (36, 39), wherein the movement of the cylinder is guided by metallic membranes.
