Abstract

L'invention a pour but de développer un nouvel agencement d'une pompe à réfrigérant pour moteurs à combustion interne dont la construction est simple et robuste, qui est techniquement facile à fabriquer et qui permet d'accéder beaucoup plus facilement à la pompe à réfrigérant dans le compartiment moteur. En outre, l'agencement peut être réalisé de façon standard avec des paramètres de fonctionnement standard même pour différentes plateformes de moteur (pompe universelle). Cet agencement réduit en même temps l' usure des composants ainsi que le bruit de fonctionnement et permet une capacité de diagnostic des fonctions de la pompe. Il réduit également sensiblement le poids des pompes à réfrigérant ainsi que les coûts de fabrication des pompes à réfrigérant et permet d'électrifier les fonctions de la pompe avec des dépenses supplémentaires minimales. L'agencement d'une pompe à réfrigérant selon l'invention se caractérise notamment par le fait que le logement de palier (2) de la pompe à réfrigérant (1) est disposé au niveau du carter de vilebrequin (9) à l'intérieur du carter d'huile (10), et une pompe à huile ( 11) est disposée dans le logement de palier (2) à côté de la pompe à réfrigérant (1). L'arbre d'entraînement (3) de la pompe à réfrigérant (1) est également l'arbre d'entraînement (3) de la pompe à huile (11). Une garniture d'étanchéité d'arbre de pompe (8) est disposée sur l'arbre d'entraînement (3), côté entraînement, près du rouet (7) de la pompe à réfrigérant (1). Une chambre de collecte de fuite (12) munie d'un perçage de fuite (13) est disposée côté pompe à huile dans le logement de palier (2), près de la garniture d'étanchéité d'arbre de pompe (8) de la pompe à réfrigérant (1). Une garniture d'étanchéité d'arbre (14) est disposée côté pompe à huile près de la chambre de collecte de fuite (12) et une pompe à fuite (15) est disposée sur l'arbre d'entraînement (3) dans la chambre de collecte de fuite (12). L'invention concerne l'agencement d'une pompe à réfrigérant (1) pour moteurs à combustion interne qui comporte un arbre d'entraînement (3) monté en rotation dans un logement de palier (2), un rouet (7) disposé à l'extrémité côté écoulement de l'arbre d'entraînement (3) dans une chambre de travail (6) munie d'un orifice d'aspiration (4) et d'un orifice d'évacuation (5), et une pompe à huile (11) disposée à l'intérieur d'un carter d'huile (10) au niveau du carter de vilebrequin (9).
