A hermetic compressor may include a frame, a crankshaft, and an oil pump. The crankshaft may be rotatably mounted to the frame. The oil pump may be mounted to a lower portion of the crankshaft to be rotatable together with the crankshaft. The oil pump may pump oil from a lower region to an upper region of a shell using centrifugal force. The crankshaft may be provided with a hollow hole therein that is inclined in two directions with respect to an axial direction of the crankshaft. This may result in increasing a dynamic pressure for scattering the oil to the upper region of the shell and an oil supply amount.

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).
