いた。(Problem to be Solved by the Invention) Since the conventional scroll compressor has a tank bottom as described above, when the compressor is stopped, especially when the compressor has been stopped for a long time, the temperature of the compressor is low. In this case, the refrigerant in the refrigeration or air conditioning equipment liquefies and flows into the compressor in large quantities, causing a large amount of saturated liquid that dissolves lubricating oil to stagnate inside the compressor. When the compressor is started under such conditions, the space where the saturated liquid has accumulated becomes the suction pressure space, so the pressure is suddenly reduced from the balanced state at startup, and the refrigerant in the saturated liquid rapidly vaporizes, causing lubrication. The viscosity of the oil causes it to foam, and the bubbles formed by the refrigerant and lubricating oil are sucked into the compression chamber through the suction passage 20.
It is compressed and discharged to the discharge muffler section 14, and the discharge pipe 16
through which it is discharged into the refrigeration or air conditioning circuit. As a result, a large amount of lubricating oil is discharged outside the compressor, reducing the lubricating oil inside the compressor, which causes abnormal wear and seizure of the sliding parts due to insufficient lubricating oil supply to the compressor sliding parts. It became.

By returning the lubricating oil to the suction pressure atmosphere, the discharge of lubricating oil to the outside of the compressor is restricted and the amount of lubricating oil inside the compressor is secured.

The same reference numerals are given to the same or corresponding parts as those of the conventional scroll compressor shown in FIG. 4, and the explanation thereof will be omitted.

。In the scroll compressor 30 of this embodiment, the closed container 13
A communication hole 31 is formed near the peripheral edges of the fixed scroll 1, the main frame 8, and the sub-frame 9, which are airtightly fitted to the fixed scroll 1, the main frame 8, and the sub-frame 9 to communicate the discharge muffler part 14 and the suction pressure atmosphere part 15. A valve device 32 for opening and closing the opening is provided on the upper surface of the fixed scroll 1 in which the opening of the discharge muffler section 14 of the communication hole 31 is formed.

路２０を通して圧縮室内へ流入する冷媒と潤滑油の混合
した泡の量を抑制できる。According to the scroll compressor of the embodiment configured as described above, when the compressor is stopped for a long time and refrigerant is condensed inside the compressor, the temperature of the compressor is approximately equal to the outside atmosphere. At this time, the valve 32a is in a state where the communication hole 31 is opened. When the compressor starts, the suction pressure atmosphere section 15 is depressurized by suction of refrigerant gas into the compression chamber, but since the communication hole 31 is open to the discharge muffler section 14, the discharge gas bypasses to the suction side. The depressurization rate (rate of pressure decrease over elapsed time) decreases. Therefore, it is possible to suppress the degree of foaming of the mixture of refrigerant and lubricating oil, and to suppress the amount of bubbles of the mixture of refrigerant and lubricating oil flowing into the compression chamber through the suction passage 20.
また圧縮室内へ流入し、吐出マフラー部１４へ吐出され

に行なわれる。Furthermore, since the lubricating oil that has flowed into the compression chamber and has been discharged to the discharge muffler section 14 is returned to the suction pressure atmosphere section 15 via the communication hole 31, the amount of lubricating oil carried out to the outside of the compressor can be reduced. If a concave portion or the like serving as an oil reservoir is provided in the discharge muffler portion 14 and a communication hole 31 is provided in the concave portion, oil return can be effectively performed.

ことができる。After a certain period of time has elapsed after the compressor is started, the temperature of the valve 32a in the high-temperature discharge gas atmosphere increases and deforms so as to close the communication hole 31. As a result, the compressor enters the normal operating state, but by optimally setting the cross-sectional area of the communication hole 31 and the opening/closing temperature of the valve 32a, the degree and duration of the foaming state can be controlled to control the amount of lubricating oil in the pressure mi. can be maintained at an appropriate value.

め、冷媒液の発泡が緩和されることがわかる。FIG. 2 shows temporal changes in the suction side and discharge side pressures of the conventional scroll compressor and the scroll compressor of the present invention from the time of startup. It can be seen that in the scroll compressor according to the embodiment of the present invention, since the suction side pressure changes gradually over time, foaming of the refrigerant liquid is alleviated.

の方法も考えられる。In the embodiment described above, the valve 32a that opens and closes the communication hole 31 is controlled by temperature changes, but the opening and closing of the valve 32a can also be controlled by using the differential pressure between the discharge side pressure and the suction side pressure, for example. Method or Tj1M! It is also possible to consider methods such as providing a valve or the like in the communication hole and electrically opening and closing it by detecting an external timer, pressure state, etc.

まわり、弁３５は着座して連通孔３１を閉じる。FIG. 3 shows another example of a device that opens and closes a valve using differential pressure. In Fig. 3, 33 is a valve holder, 34
35 is a spring, 35 is a valve, and 36 is a retaining ring. According to such a valve device, if the differential pressure between the discharge side pressure and the suction side pressure is less than the set value, the valve 35 is pushed up by the spring 34 and the wave path is opened, and the discharge is started after a certain period of time after the compressor is started. When the pressure difference between the side pressure and the suction side pressure increases, the force due to the pressure difference exceeds the additional force of the spring 34, and the valve 35 is seated to close the communication hole 31.
なお、この連通孔及び弁装置を密閉容器の外部に設けて
も同等の効果を有することは明らかである。Note that it is clear that the same effect can be obtained even if the communication hole and the valve device are provided outside the closed container.
