Abstract

La présente invention concerne un ressort de support (200) comprenant: une première partie d'enroulement (210) qui est un fil métallique enroulé plusieurs fois avec le même diamètre externe; une deuxième partie d'enroulement (220) adjacente à la première partie d'enroulement et formée comme un fil métallique enroulé plusieurs fois avec un même diamètre externe différent de celui de la première partie d'enroulement (210); et une troisième partie d'enroulement (230) adjacente à la deuxième partie d'enroulement (220) et formée comme un fil métallique enroulé plusieurs fois avec le même diamètre externe que la première partie d'enroulement (210). Ce ressort de support (220) est positionné entre deux composants de manière à absorber efficacement les vibrations et un choc produit au niveau d'un composant. Un compresseur comportant ce ressort de support (200) minimise la production de vibrations parasites qui empêchent toute collision parasite ainsi que tout dégât occasionné à un composant.
