The present invention relates to a lubricating oil transport system in a compressor, in which:

System for transporting lubricating oil in a compressor

The refrigeration compressor includes a cylinder block carrying a crankshaft and a stator of an electric motor, whose rotor is mounted to the crankshaft. An oil pump including: a tubular sleeve affixed to the crankshaft or to the rotor with a pump body internal to the tubular sleeve and connected to the cylinder block. A fixation rod is articulated to the cylinder block or stator and has a lower portion angularly and freely displaced orthogonally to the rotational axis and around which the lower end portion of the pump body is axially retained and slidably mounted, orthogonally and coplanar to the rotation axis of the rotor.
