Structure diagram of single vane compressor_Main features of single vane compressor

　　 The basic structure and working principle of single slide compressor.<img src="{{media url=&quot;Structure_diagram_of_single_vane_compressor_Main_features_of_single_vane_compressor.jpg&quot;}}" alt="" /> Single sliding vane compressor is also called scraper compressor or rolling rotor compressor. Its structure is shown in Figure 3-7. A cylindrical eccentric rotor (also called a piston) is installed in the cylinder, and the center of rotation of the rotor coincides with the center of the cylinder. In the middle of the upper part of the cylinder, a scraper that can slide up and down is installed. Due to the force of the spring,<img src="{{media url=&quot;Structure_diagram_of_single_vane_compressor_Main_features_of_single_vane_compressor2.jpg&quot;}}" alt="" />
