压缩原理：压缩是通过阴阳转子在一个气缸内同时啮合来完成的。主转子有四个

Compression principle: Compression is accomplished by Yin and Yang rotors simultaneously meshing in a cylinder. The main rotor has four helical convex teeth distributed at 90 degrees to each other. There are six female rotors which are distributed at 60 degrees to each other in a spiral groove to mesh with male rotor convex teeth. The air inlet is located at the top of the compressor cylinder, close to the side of the drive shaft. The exhaust port is on the opposite side of the bottom of the cylinder. When the rotor has not meshed at the suction port, air flows into the cavity of the male teeth of the male rotor and the grooves of the female rotor, and the compression cycle begins.

Compression principle: Compression is accomplished by simultaneously meshing in a cylinder by yin and yang rotors. The main rotor has four each other to become 90 degrees distributed on spiral convex teeth. The yin rotor has six each other become 60 degrees distributed in the spiral groove and the yang rotor lugs engaged. The air inlet is located on the top of the compressor cylinder, close to the side of the drive shaft. The exhaust port is on the opposite side of the bottom of the cylinder. When the rotor is not engaged in the suction port, air flows into the cavity of the yang rotor convex teeth and the vulva groove, at which point the compression cycle begins.

Compression principle: compression is accomplished by engaging the male and female rotors in one cylinder at the same time. The main rotor has four 90 degrees to each other and distributed on the spiral teeth. The female rotor has six mutually formed 60 degrees, which are distributed in the spiral groove and mesh with the male rotor convex teeth. The air inlet is located at the top of the compressor cylinder near the side of the drive shaft. The exhaust port is on the opposite side of the bottom of the cylinder. When the rotor is not meshed in the suction port, the air flows into the cavity of the male rotor and the female rotor groove, and the compression cycle begins.
