The disclosure discloses a compressor pump body, a compressor and an air conditioner. The compressor pump body includes a sliding vane, a first flange and a second flange. The sliding vane includes a main body. The main body is provided with a first surface and a second surface which are arranged opposite to each other. The first surface abuts against the first flange, and the second surface abuts against the second flange. The first surface and/or the second surface are/is provided with an enlargement portion. An exhaust port is formed in the first flange and/or the second flange. When the sliding vane rotates to sweep the exhaust port, the enlargement portion can prevent two sides of the sliding vane in the rotation direction from communicating by means of the exhaust port.

The disclosure discloses a slide vane, a pump body assembly, a compressor and an air conditioner having the same. The pump body assembly includes a cylinder assembly, a flange portion, a rotating shaft and the slide vane. The flange portion is connected to the cylinder assembly, a working cavity is formed between the flange portion and the cylinder assembly, and an avoidance portion is provided on a surface, located in the working cavity, of the flange portion. A limiting structure is provided in an accommodation portion. The limiting structure is provided with an avoidance position in the accommodation portion, and at least part of the limiting structure is provided with a limiting position protruded out of a surface of the accommodation portion. Such a configuration avoids friction occurring between the head of the slide vane and the cavity wall of the working cavity.

A compressor pump structure has a cylinder sleeve provided between an upper flange and a lower flange; a cylinder is provided inside the cylinder sleeve; a piston is slidably arranged inside the cylinder; a volume-variable chamber is formed among the cylinder sleeve, the cylinder and the piston; a rotating shaft passes through the piston, the axis of the rotating shaft being eccentrically disposed with respect to the axis of the cylinder with a fixed eccentricity; the rotating shaft drives the piston and the cylinder to rotate; and the piston slides within the cylinder while rotating so as to change the volume of the volume-variable chamber. Further disclosed is a compressor which comprises a compressor pump structure.
