<p>The air cushion comprises a flexible annular membrane (11) of reinforced rubber, with its ends (12,15) fixed to a plate and a piston. The membrane has a more or less continuous thickness over its whole area, and is fixed to the plate and piston by a chemical adhesion process during vulcanisation. The rubber can be of an elastomer with a carbon black filler. At least one of the two end components has a cup (13, 16) located inside the corresponding end of the membrane and adhering to it, and an outer ring (14, 17) surrounds each end of the membrane and is also joined to it during vulcanisation.</p> |
