Abstract

Disclosed is a crank shaft, including a central rotation shaft, a first eccentric component, a second eccentric component, a disc partition plate and an annular partition plate, wherein the disc partition plate is disposed between the first eccentric component and the second eccentric component, and is integrally formed with the central rotation shaft, and the annular partition plate is sleeved outside the disc partition plate. The crank shaft can prevent the occurrence of leakage between the partition plate and a roller while increasing an eccentricity of the crank shaft and improving operating performances of a compressor. Further disclosed are a pump body assembly having the crank shaft and a compressor.
