摘要： PURPOSE:To raise the efficiency of a compressor, by reducing the expansion loss and the frictional loss of a fluid by connecting a return channel having a return valve to the outlet of a U-turn section formed at the outlet of a diffuser, and connecting an annular chamber having a discharge opening to the outlet of said return channel. CONSTITUTION:Since the velocity energy of a fluid is recovered considerably while passing through a diffuser 4, the speed of fluid flow is decreased and the pressure is increased. The fluid enters into a U-turn section 12, where the speed of fluid flow is further decreased and the pressure is further increased, and then the fluid enters into an inlet end 16 of a return vane 13 at the minimum speed. Thereafter, the fluid is introduced into an annular chamber 18 via a return channel 14 at a speed decreased to a level lower than the discharge speed at a discharge opening 6, and then discharged to the outside from the discharge opening 6. Thus, since the pressure of fluid is raised continuously by decreasing the speed of fluid flow from that at the outlet of the diffuser 4 to that at the outlet of the return channel 14 and residual energy at the outlet of the diffuser 4 can be recovered efficiently, it is enabled to raise the efficiency of a compressor as a whole.
摘要翻译：目的：为了提高压缩机的效率，通过将具有回流阀的返回通道连接到形成在扩散器的出口处的U形转弯部分的出口，通过减小膨胀损失和流体的摩擦损失，并连接环形室具有通向所述返回通道出口的排放口。构成：由于在通过扩散器4时流体的速度能量被大大地恢复，所以流体流动的速度降低并且压力增加。流体进入U形转弯部分12，其中流体流动的速度进一步降低并且压力进一步增加，然后流体以最小速度进入回流叶片13的入口端部16。此后，流体通过返回通道14以降低到排出口6处的排出速度的水平的速度被引入到环形室18中，然后从排出口6排出到外部。因此，由于流体的压力通过降低从扩散器4的出口处的流体流速到返回通道14的出口处的流动速度而连续升高，并且能够有效地恢复扩散器4的出口处的剩余能量，提高整体压缩机的效率。
