Abstract

L'invention concerne un dispositif permettant de fixer le carter (2) d'un compresseur frigorifique sur un conteneur entourant un volume de réfrigération, ledit carter (2) pouvant être fixé sur un élément support (1) placé sur le conteneur au moyen d'un nombre quelconque d'éléments d'assemblage (3), au moins un élément d'assemblage (3) pouvant être bloqué par serrage ou encliquetage dans au moins un logement correspondant (4) et l'élément d'assemblage (3) ou le logement (4) pouvant être placé de manière sélective sur le carter (2) ou sur l'élément de support (1). L'objectif de l'invention est de permettre une fixation simple, rapide et néanmoins fiable du compresseur frigorifique sur l'élément support (1). A cet effet, le carter (2) peut être amené d'une première position de montage, dans laquelle l'élément d'assemblage (3) est inséré dans le logement (4), à une position de fonctionnement, dans laquelle l'élément d'assemblage (3) est bloqué par serrage ou encliquetage dans le logement (4).
