A compressor assembly including a crankshaft with an axial oil passageway therein. An oil pump booster is mounted on the crankshaft to increase the oil flow rate through the axial oil passage. The oil pump booster includes a counterweight and an enclosed channel extending in the radial direction communicating with the axial passageway of the crankshaft. During rotation of the compressor crankshaft, the radial oil channel is likewise rotated creating a centrifugal force or reduced pressure area to increase the oil flow through the axial passage.
La présente invention porte sur un compresseur comportant un vilebrequin traversé par un passage d'huile axial. Une pompe de surpression est montée sur le vilebrequin pour accroître le débit d'huile à travers le passage axial. La pompe de surpression incorpore un contrepoids et un canal fermé pratiqué dans une direction radiale et en communication avec le passage axial traversant le vilebrequin. Durant la rotation du vilebrequin du compresseur, le mouvement de rotation imprimé au canal radial produit une force centrifuge qui crée une zone de dépression, laquelle est utilisée pour accroître le débit d'huile à travers le passage axial.
