種々の問題点がある。That is, the low-temperature, low-pressure refrigerant gas that has passed through the evaporator 4 is sucked into the cylinder 5 through the suction passage 8 of the compressor 1, and is moved through the discharge passage 9 and the discharge valve by the eccentric rotation of the crankshaft 6 and roller 7. It is discharged at high temperature and high pressure into the internal space of the compressor 1 through the discharge pipe 10 and into the condenser 2 through the discharge pipe.
From Capilla II 2 to Dojin 61] In the compressor and refrigeration cycle configured as described above, high temperature and high pressure refrigerant gas is released into the compressor container, so the back surface of the vane 10' An increase in finger resistance between the vane 10' and the roller luff due to the pressing force applied to the pump, a decrease in volumetric efficiency due to leakage of high-pressure refrigerant from around the pump part to the low-pressure side chamber in the cylinder 5, a decrease in suction efficiency due to overheating of the suction gas, There are various problems such as a decrease in lubrication efficiency due to increased penetration of high-pressure refrigerant into the drowning oil, and a decrease in cooling rate in the refrigeration cycle immediately after startup due to retention of high-pressure refrigerant in the compressor.
本発明は上記欠点を改良する為に提案されたものであり
、圧縮機内部空間を適切な中間圧力に保持して、圧縮機
の効率向上を図ることを目的としたものである。The present invention was proposed in order to improve the above-mentioned drawbacks, and aims to improve the efficiency of the compressor by maintaining the internal space of the compressor at an appropriate intermediate pressure.
〔発明の概要〕

力に保持させ圧縮機の効率向上を図ったものである。[Summary of the invention] In other words, the high-temperature, high-pressure refrigerant gas generated in the compressor is not discharged into the internal space of the compressor (it is directly discharged to the condenser, while a part of the circulating refrigerant is branched off from the outlet side of the condenser). The refrigerant is then reduced to an appropriate pressure by an auxiliary capillary and introduced into the internal space of the compressor to maintain the internal pressure of the compressor at an appropriate intermediate pressure, thereby improving the efficiency of the compressor.
以下本発明を第３図〜第４図に示す一実施例により説明

いる。The compressor 11 has a discharge silencer 14 attached to the cylinder 12 to completely seal the area around the discharge valve 13.
and a discharge pipe 1 which is connected to this and communicates with the compressor vessel.
5. Pipe 20 connected in an open state to the internal space of the compressor

プ２２を第１キヤビ１７の中間に接続して構成する。On the other hand, the refrigeration cycle is equipped with a condenser 16 that communicates with the discharge pipe 15 and a starter generator 18 that communicates with the suction vibe 19. The pipe 22 is connected to the outlet side of the vessel 16 and further connected to the middle of the first cavity 17.

に保持さｒする。In the refrigeration cycle configured as described above, the high-temperature, high-pressure refrigerant gas generated within the compressor is directly discharged outside the compressor without remaining inside the compressor. The refrigerant that has been appropriately depressurized and cooled by the cavity 21 is returned, circulated inside the compressor, and returned to the middle of the first cavity 17, so that the inside of the compressor is maintained at an appropriate intermediate pressure state.

期待される。In a refrigeration cycle with such a configuration, the force applied to the back of the vane inside the compressor is reduced, which reduces friction loss between the vane and the roller, reduces the amount of refrigerant gas entering the pump low pressure chamber, and superheats the suction gas. It is expected to have effects such as improving volumetric efficiency by lowering the temperature, improving lubrication properties by reducing the amount of refrigerant dissolved in the lubricating oil, and improving the cooling rate on the refrigeration cycle.

Because of this, we can expect a longer lifespan for city machinery and pump parts.
