Patent number: 11525446Abstract: A compressor and an air conditioner are provided. The compressor includes a main shaft, a first cylinder and a second cylinder. The main shaft sequentially passes through the first cylinder and the second cylinder and can rotate therein, to compress refrigerant entering the first cylinder and the second cylinder. The second cylinder has an inner cavity capable of receiving the main shaft. A volume variation control cavity in communication with the inner cavity is provided in a side wall of the inner cavity, and a sliding vane is provided inside the volume variation control cavity. The volume variation control cavity can be selectively connected to a gas inlet and a gas outlet of the compressor, to change gas pressure in the volume variation control cavity, and drive the sliding vane to abut against or be separated from the main shaft by the gas pressure in the volume variation control cavity.Type: GrantFiled: May 30, 2018Date of Patent: December 13, 2022Assignee: GREEN REFRIGERATION EQUIPMENT ENGINEERING RESEARCH CENTER OF ZHUHAI GREE CO., LTD.Inventors: Yanjun Hu, Hui Huang, Yusheng Hu, Huijun Wei, Ouxiang Yang, Peizhen Que, Yuanbin Zhai, Liu Xiang, Wang Miao
