Abstract

The present application belongs to the technical field of compressors. Provided are a pump body assembly, a compressor, and an air conditioner. The pump body assembly comprises an air cylinder and an oil guide structure. A partition plate covers one side of the air cylinder, and a cylinder cover covers the other side of the air cylinder. The air cylinder has a sliding sheet groove allowing a sliding sheet to be mounted. A first oil groove extending in an axial direction of the air cylinder is disposed in a side wall of the sliding sheet groove. The partition plate is provided with an oil hole thereon, and the oil hole is opposite to the side of the sliding sheet away from the cylinder cover and is in communication with the first oil groove. The oil guide structure is configured to guide a lubricating oil to the oil hole, so that the lubricating oil flows into the first oil groove via the oil hole. A backpressure cavity is formed between the side of the sliding sheet away from the partition plate and the cylinder cover, and the oil guide structure is further configured to guide the lubricating oil into the backpressure cavity, so that the backpressure cavity provides force for the sliding sheet to be relatively close to the partition plate. According to the technical scheme of the present application, by means of the arranged backpressure cavity, backpressure can be provided for the sliding sheet to balance the axial impact of the lubricating oil in the oil hole on the sliding sheet, so that the axial stress of the sliding sheet is more balanced, thereby reducing the end surface abrasion of the sliding sheet.
