Here, a conventional example will be described with reference to this publication. In FIG. 7, a hermetic compressor 50 has a hermetic container 51 in which a compressor, an electric motor (not shown) and the like are arranged, and a predetermined amount of oil 52 is preliminarily sealed in the lower portion. 53 is a rotating shaft, 54 is oil 5 at one end
It is an oil supply pipe immersed in 2. The oil supply pipe has the other end slidably inserted into a circular recess 55, which is countersunk to the lower end of the rotary shaft 53, and the rotary shaft 53 and the oil supply pipe 54 have a double portion having an outer portion 56 and an inner portion 57. Ring bellows 58
(Temperature sensitive member). The lower end surface of the rotary shaft 53 and the upper end of the bellows 58 are fixed by adhesion or the like, and the lower end of the bellows 58 is fixed by adhesion or the like to a holding plate 59 that is adhered to the oil supply pipe 54. The inner diameter of the bellows 58 is slightly larger than the outer diameter of the oil supply pipe 54.
A heat-expandable gas is hermetically filled in the inside 8.

油量を確保できるようにしている。When the hermetic compressor 50 has a high ambient temperature, the internal temperature also rises, and the gas in the bellows 58 has a large expansion degree and the bellows height becomes large. As a result,
The amount of the oil supply pipe 54 immersed in the oil 52 increases, and the oil viscosity decreases due to high temperature, so that the amount of oil supply pipe 54 and the oil can be prevented from decreasing due to an increase in the amount of slip between the oil supply pipe 54 and the oil. I am trying.

きるようにしている。Further, at a low ambient temperature, the hermetic compressor 50
Since the internal temperature of the bellows is also reduced, the bellows 58 contracts more than at high ambient temperature, and the height of the bellows decreases. Then, the immersion amount of the oil supply pipe 54 in the oil 52 decreases,
By reducing the sliding friction loss (stirring resistance) between the inner and outer circumferences of the oil supply pipe 54 and the oil 52, it is possible to reduce the compressor operation input. On the other hand, since the oil 52 is also at a low temperature at the same time, its viscosity is high and the oil supply capacity of the oil supply pipe 54 can be sufficiently secured.

Because it slides up and down in the circular recess 55 of the bellows 58
There was a problem in durability such that the thermally expansive gas in the bellows leaks due to its own fatigue and the temperature-sensing function is lost. Further, between the bellows 58 and the oil supply pipe 54, the oil supplied from the oil supply pipe to each sliding portion is accumulated, and there is a problem that the oil is not supplied to each sliding portion at the time of startup.

下する。When the compressor is stopped, the oil surface of the oil supply section 21 is at the same level as the oil surface of the oil recovery section 22, and the oil supply pipe 19 is deeply immersed in the oil of the oil supply section. Therefore, the amount of oil pumped up from the oil supply pipe 19 at the time of starting is large. Moreover, the oil supply unit 21
The oil surfaces of the oil recovery section 22 and the oil recovery section 22 are at the same height, and the oil does not flow from the oil recovery section 22 to the oil supply section 21 through the small hole 23 of the partition fitting 20. If the operation is continued in this state, the amount of oil in the oil supply unit 21 decreases, the oil surface lowers, and the amount of oil immersed in the oil supply pipe 19 decreases. In addition, since the oil surface of the oil supply unit 21 is lowered, a difference occurs in the oil surface between the oil supply unit and the oil recovery unit 22, and the oil recovery unit 22 moves from the oil recovery unit 22 to the oil supply unit 21 through the small hole 23. Oil flows in. The amount of oil flowing from the oil recovery part 22 to the oil supply part 21 is determined by the passage area of the small hole 23, the drop of the oil surface between the oil recovery part 22 and the oil supply part 21, and the viscosity of the oil. That is, at the time of start-up, the viscosity of the oil is high, the amount of oil in the oil supply unit 21 pumped from the oil supply pipe 19 is larger than the amount of oil flowing in from the oil recovery unit 22 through the small holes 23, and the oil surface is descend.

る。When the immersion amount of oil in the oil supply pipe 19 decreases, the pumping amount of oil decreases. Then, as shown in FIG. 4, the oil supply part 21 is moved from the oil recovery part 22 to the oil supply part 2 through the pumping amount of the oil supply pipe 19 and the small hole 23.
Since the amount of oil flowing into 1 becomes equal at the intersection point P, the oil surface is stabilized at a position lower than the oil surface of the oil recovery unit. Therefore, the length of the oil supply pipe 19 immersed in the oil is shortened, the stirring resistance of the oil is reduced, the input during operation is reduced, the ripple of the oil is suppressed, and the noise due to the ripple phenomenon of the oil can be reduced. I have to.

うにしている。Further, oil has a high viscosity at low temperatures, and the viscosity decreases as the temperature rises. Therefore, at the time of starting at low temperature, the inflow resistance of the oil from the oil recovery unit 22 to the oil supply unit 21 increases, the oil surface of the oil supply unit 21 further decreases, and the stirring resistance of the oil supply pipe 19 also decreases. At this time, the amount of oil supplied to each sliding portion is also reduced, but since the temperature of the compression element 3 is low, much oil is not required. Further, when the temperature is high, the inflow resistance of oil decreases, and the oil surface of the oil supply unit 21 increases. And
The oil supply pipe 19 ensures a sufficient amount of oil supply to each sliding portion because the amount of oil soaked is longer than that at the time of starting at low temperature.

However, as shown in FIG. 5, the partition metal fitting 24 is formed with a slit-shaped groove 25 in the vertical direction. However, it goes without saying that it has the same effect.
