Abstract

Cette invention se rapporte à une butée pour un compresseur comprenant : un réservoir hermétique (10) présentant un espace interne prédéterminé ; un ensemble de compression (20) disposé dans le réservoir hermétique (10) et servant à comprimer un gaz sous l'effet de la force motrice d'un moteur d'entraînement ; et un moyen de support élastique monté entre le réservoir hermétique (10) et l'ensemble de compression (20) et servant de support élastique à l'ensemble de compression (20). Cette butée comprend : un limiteur de mouvement placé au niveau du réservoir hermétique et de l'ensemble de compression et destiné à limiter le mouvement de l'ensemble de compression (20) dans le sens horizontal et le sens vertical. Ainsi, une collision entre l'ensemble de compression (20) disposé à l'intérieur du réservoir hermétique (10) et le réservoir hermétique (10) est empêchée, ce qui évite tout dommage aux composants et réduit l'apparition du bruit de collision. En outre, la structure et les composants de construction sont simplifiés et le nombre de postes de montage de l'ensemble est réduit.
