Abstract

L'invention a pour but d'obtenir un réservoir collecteur (4) pour l'évaporation de liquide condensé dans un compresseur de petite machine frigorifique, réservoir au moyen duquel la chaleur cédée par ledit compresseur est utilisée de manière optimale, qui peut être fabriqué de manière simple et économique et qui peut être monté sur le carter d'un compresseur. A cet effet, l'invention est caractérisée en ce que le réservoir collecteur (4) est fabriqué sous forme d'une pièce en matière plastique emboutie dans un dispositif de réception, directement sur le carter du compresseur. Cette pièce s'adapte exactement à la forme du dispositif de réception (6), de sorte que l'espace existant entre le carter de compresseur et le réservoir collecteur (4) est généralement, ou bien totalement exclu, ou bien réduit au minimum. Un élément de fixation (2) disposé sur le pourtour extérieur de l'élément de recouvrement (1), garantit une retenue optimale du réservoir collecteur (4). On supprime ainsi les mesures coûteuses et compliquées de protection anticorrosion, cependant que la puissance d'évaporation et le coefficient d'efficacité (COP) du compresseur pour petite machine frigorifique sont optimisés.
