Claims

[Scope of utility model registration request]

An oil supply passage is provided in the crankshaft A, and this oil supply passage is opened to the oil sump C of the compressor via the thrust receiver B at the shaft end 6 of the crankshaft A, and the centrifugal force caused by the rotation of the crankshaft A The oil supply mechanism is configured to pump up oil from the oil sump C to supply oil, and the crankshaft A is provided with a first passage 12 on the center side that extends in the axial direction of the crankshaft A and opens at the end of the shaft. and a second passage 13 located radially outward of the passage 12, communicating with the first passage 12 near the shaft end 6 of the crankshaft A, extending in the radial direction and opening at the outer peripheral surface. The third passage 14 and the shaft end 6 of the crankshaft A
fourth passages 15a, 15b, 15 communicating with the second passage 13 at a position away from the radial direction and opening at the outer circumferential surface;
A cylindrical chamber 16 that communicates with the third passage 14 is provided at the shaft end of the crankshaft A, and a cylindrical chamber 16 that communicates with the third passage 14 is provided in the thrust receiver B. An oil supply mechanism for a hermetic compressor, characterized in that a groove 18 and a through hole 19 opening the first passage 12 to the oil reservoir C are provided in a spaced manner.
