Abstract
Abstract An antivibration elastic support, particularly for the power plants of autovehicles. It essentially consists of an elastomer hollow unit (1), made to adhere to two rigid reinforcements (2)-(3) during vulcanization, the lower reinforcement (3) exhibiting an opening that can be stopped by an additional rigid reinforcement (4), the fluid-tight chamber (5), consisting of the walls of the hollow elastomer unit (1) and the reinforcements (2)-(4), being at least partially filled with a material that is easily deformable by outside application of energy, with absorption of the latter.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
131 words
An antivibration elastic support comprising: a first and second reinforcement member; an elastomeric unit interconnecting said first and second reinforcement member and having a first fluid tight chamber formed therein; a movable member connected to said first reinforcement member and including a base; a housing connected to said second reinforcement member and forming a second fluid tight chamber, said second fluid tight chamber having a damping material positioned therein; a container within which said base of said movable member is positioned; a piston located within said housing; an elastomeric element secured between said housing and said second reinforcement member wherein said elastomeric element further interconnects said container and said piston; and at least one elastomer member positioned between said base of said movable member and an inner wall of said container.
Claim 2
Dependent Claim
131 words
An antivibration elastic support comprising: a first and second reinforcement member; an elastomeric unit interconnecting said first and second reinforcement member and having a first fluid tight chamber formed therein; a movable member connected to said first reinforcement member and including a base; a housing connected to said second reinforcement member and forming a second fluid tight chamber, said second fluid tight chamber having a damping material positioned therein; a container within which said base of said movable member is positioned; a piston located within said housing; an elastomeric element secured between said housing and said second reinforcement member wherein said elastomeric element further interconnects said container and said piston; and at least one elastomer member positioned between said base of said movable member and an inner wall of said container.
Claim 3
Dependent Claim
29 words
