Abstract

L'invention a pour objet un dément amortisseur pour isoler des objets à l'égard des vibrations. L'invention cet caractérisée en ce qu'en superposant des plaques de tôle munies de renflements ou calottes 4, on obtient une courbe de constante d'élasticité de forme << haut - bas - haut >>, le minimum de constante d'élasticité correspondant à la charge statique ou nominale. L'invention est particulièrement adaptée à l'isolation des machines.The object of the invention is a shock-absorbing element for isolating objects with regard to vibrations. The invention is characterized in that by superimposing sheet metal plates provided with bulges or caps 4, one obtains a curve of elasticity constant of shape "up - down - up", the minimum of elasticity constant corresponding to the static or nominal load. The invention is particularly suitable for the insulation of machines.
