Abstract

Le compresseur frigorifique comporte un carter de compresseur (2) ; un réservoir d’huile (13) agencé dans le carter de compresseur (2) ; et un agencement de capteur de niveau d’huile (14) configuré pour détecter un niveau d’huile dans le réservoir d’huile (13), l’agencement de capteur de niveau d’huile (14) comportant un élément tubulaire (16) fixé au carter de compresseur (2) et un élément flottant (17) entourant l’élément tubulaire (16) et étant monté de manière mobile par rapport à l’élément tubulaire (16). Le carter de compresseur (2) comporte une ouverture de passage (24) et les dimensions de l’élément tubulaire (16), de l’élément flottant (17) et de l’ouverture de passage (24) sont définies de manière à permettre une insertion de l’élément tubulaire (16) et de l’élément flottant (17) dans le carter de compresseur (2) et leur retrait de celui-ci à travers l’ouverture de passage (24).
