[0072] detailed description:
[0073] Such as figure 1 As shown, during the operation of the compressor, the oil circuit system in the traditional scroll compressor is that the oil in the oil pool at the bottom of the compressor enters the internal oil supply hole of the crankshaft through the oil suction pipe and the oil guide plate. The hole is an eccentric structure, which can generate centrifugal force, so that the oil in the oil supply hole can smoothly rise to the head of the crankshaft. After the oil passes through the axial oil outlet hole, it lubricates the rotor bearing, flows into the back pressure oil pool, and then drains the oil through the oil return pipe Return to the oil pool at the bottom of the compressor to form an oil circuit.
[0074] In the crankshaft oil path structure of the scroll compressor of the present invention, the oil passing through the oil hole 2 rises to the crankshaft head 12. The oil path at the head is divided into two or more paths, and the a...
