いはベー７１２との隙間等を通シ、吸入側に逆流する。In the above configuration, the rotation of the rotor 3 is transmitted to the shaft 9, the roller 11 fitted in the eccentric part 10 rotates eccentrically in the compression chamber 8, and the vane 12 pressed against the roller 6 causes the inside of the compression chamber 8 to be rotated. By dividing the pressure into a high pressure side and a low pressure side, gas sucked through the suction pipe 13 is continuously compressed. The compressed high-pressure gas is once released into the sealed volume N1 and then discharged from the discharge side 14. At this time, the pulp 21 is pushed up by the force of the gas, and the suction gas continues into the suction pipe 1.
3 and flows into the compression chamber 8. Further, since the impulse pipe 34 is at low pressure and the bellows 31U is contracted, the nose 32 is far away from the pulp pace 33, and the high pressure gas is
from the vessel to the evaporator. Next, when the rotor 3 stops rotating, the compressed high-pressure gas in the sealed container 1 passes through the gaps between the cylinder 5 and the main bearing 6, the sub-bearing 7, or the gap between the bay 712, etc., and passes through the suction side. backflow to.

The problem arises of heating the evaporator, but the check valve 19
Inside, the pulp 21 is brought into close contact with the pulp sheet 20 due to the backflow of high pressure gas and its own weight, and the backflow of the high pressure gas is stopped at the check valve 19.

前記蒸発器の加熱全防止することとなる。In addition, the high-pressure gas I-1 pressure pipe 34 that has flowed back is passed through and the hollows 31' are extended, so the nose 32 is pressed against the valve base 33, and the connection between the condenser m11 and the evaporator is cut off. be done. This means that the
This completely prevents heating of the evaporator due to the slow flow of high-pressure gas from the reactor to the evaporator.

器へ流れる。In this configuration, the operation will be explained first. When the rotary compressor is operating, the reed 25 is pressed against the coil spring 26 side by the force of the suction gas against the spring force of the coil spring 26, and the suction gas passes through the pass hole 29 and enters the pressure chamber. 8. In addition, the pressure in the pressure path 4o is low, and the bellows 31 is also under low pressure through the entire connecting pipe 41. Since the bellows 31 is contracted, the nose 32 is separated from the pulp pace 33, and the high pressure gas is condensed. flows from the vessel to the evaporator.
