Abstract
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.
