ABSTRACT:
A hydraulic antivibratory device is provided, comprising two rigid frames (1,2); an elastomer body (3) connecting the two frames together and forming two sealed chambers (A, B) at least partially therewith; a restricted passage (7) causing the two chambers to communicate permanently with each other; a liquid mass (L) filling the two chambers and the restricted passage; and a deformable valve (8) partially defining one of the two chambers (A), and mounted between two grids (9, 10). This valve is in the form of a biconvex lens, only the central part of which is in permanent contact with the two grids and is clamped therebetween.
