摘要: The present invention relates to a lubricating oil transport system in a compressor, in which:
the rotating shaft (3) has at least one concavity (35) that extends over part of the rotating surface (33) in contact with the internal surface (11) of the rotor (1) and at least one restrictor hole (34) that communicates with the internal region of the rotating shaft (3) and with the concavity (35);
the rotor (1) comprises a circumferential channel (12) and at least one radial channel (13) extending through the inner wall (11) of the rotor (1);
the radial channel (13) is arranged around the circumferential channel (12);
said circumferential channel (12) and the radial channel (13) communicating with the concavity (35);
the circumferential channel (12), the radial channel (13) and the concavity (35) transport oil for cooling the upper part of the rotor (1) and the stator (2).
