である。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an oil supply mechanism for a hermetic compressor.
以下従来技術を図面に従い説明する。 The prior art will be explained below with reference to the drawings.

摩耗などの現象を発生する可能性がある。 FIG. 1 is a longitudinal cross-sectional view of the main parts of the hermetic compressor 1. FIG. Cylindrical compression chamber 3 provided in cylinder 2
A roller 6 fitted to the eccentric portion 5 of the shaft 4 is disposed inside the cylinder 2, and a vane 7 is fitted to the cylinder 2. An upper bearing 8 and a lower bearing 9 are fixed to the cylinder 2. Lubricating oil 11 is stored in the lower part of the container 10. An oil supply device 13 is press-fitted into the lower part of the vertical hole 12, protrudes downward from the shaft 4, and is immersed in the lubricating oil 11. When the shaft 4 rotates, the lubricating oil 11 present near the inner wall of the oil supply device 13 receives an upward force due to centrifugal force and viscosity, and is pushed up. When the pushed up lubricating oil 11 reaches the lower end of the twisting plate 14 inscribed in the vertical hole 12, the lubricating oil 11 ascends the flow path formed by the twisting plate 14 and the vertical hole 12, and enters the horizontal hole of the shaft 4. When reaching clearances 15, 16, and 17, oil is supplied to clearances 18, 19, and 20. On the other hand, oil feeder 13
Lubricating oil 11 is sucked into the shaft, so as long as the shaft 4 is rotating, the oil is supplied, but as the rotation speed decreases, the amount of oil supplied becomes insufficient, and the upper bearing 8,
The roller 6, lower bearing 9 and shaft 4 are engaged,
Phenomena such as wear may occur.
本発明は係る欠点を解消するものである。 The present invention overcomes these drawbacks.

Make a diagonal cut in the thin plate, raise the cut,
Form into a cylindrical shape with the raised side facing inside.
A small hole is made at the upper end of the raised cut and then inscribed in the vertical hole of the shaft, so that the horizontal hole of the shaft is connected to the vertical hole through the small hole.

FIG. 2 is an enlarged vertical cross-sectional view of the main parts showing one embodiment of the present invention. The lubricating oil 11 pushed up by the oil supply piece 13 ascends through a flow path 22 provided in an oil supply pump 21 inscribed in the vertical hole 12, and is supplied to the clearance 24 from the horizontal hole 23. With this method of refueling, each side hole can be refueled separately. In addition, as in the conventional case, the twist plate 14
In the flow path formed by the vertical hole 12 and the twist plate 1
4 and the vertical hole 12 was a major cause of oil supply loss, but in the present invention, the flow path is formed from one plate, so the loss is extremely small.
以上の２点から給油量は非常に大量となり、咬

Due to the above two points, the amount of oil supplied was extremely large, and there was no occurrence of biting wear.
尚、給油器２５を一体化して成形すれば給油器
２５から給油ポンプ２１への潤滑油１１の流れが
円滑になり給油量はさらに増加する。 Note that if the oil supply device 25 is integrally molded, the flow of the lubricating oil 11 from the oil supply device 25 to the oil supply pump 21 will be smooth, and the amount of oil supplied will further increase.
