| description | The utility model discloses a three-cavity sliding vane type compressor cylinder, which is characterized in that a cylinder profile on the cylinder consists of a secondary spiral line and comprises three sections of suction section curves and three sections of discharge section curves; all sections of composition curves are completely and smoothly connected, the first-order derivative is continuous and smooth, and the second-order derivative is continuous; the size of the central angle corresponding to the first suction section curve is alpha, the size of the central angle corresponding to thefirst discharge section curve is beta, alpha is smaller than beta, and alpha + beta is equal to 120 degrees. Three asymmetric working cavities are formed between the air cylinder and the rotor, the situation that the working cavities are symmetric about the axis of a rotation center through the center line of the rotation center does not exist, the exhaust volume is reduced, the exhaust pressureis increased, the pressure |
