Abstract (en)

[origin: EP1878941A1] The device has a thermoplastic elastic block (1) delimiting a chamber containing hydraulic control with an non-deformable end plate. The block is successively subjected to deformation by compression above elastic limit of an elastomer and a relaxation. The block has a peripheral bead which is elastically compressed between a plate and a non-deformable annulus which surrounds the block. The bead is housed in a peripheral groove of the annulus. An independent claim is also included for a method for fabricating a device associating a tubular compression spring and a hydraulic damper.
