The utility model relates to a cylinder
assembly, pump body structure and compressor, cylinder
assembly includes cylinder body, sliding block, the middle part of cylinder body is passed through its axial both ends and is provided with compression cavity, the inside wall of compression cavity is recessed and is formed with the sliding slot along the radial direction, the side of sliding slot away from compression cavity is spaced and is provided with the first cooperation part and the second cooperation part with the distance not equal with the center line of compression cavity along the axial direction, sliding block is slidably arranged in the sliding slot, the side surface of sliding block close to compression cavity is eccentric
circular surface, the side of sliding block away from compression cavity is spaced and is provided with the first
abutment of abutting with the first cooperation part and the second
abutment of abutting with the second cooperation part along the axial direction, the utility model promotes the
back pressure of sliding block through reducing the pressure of the end of sliding block and
piston contact, and through the design of the first
abutment and the second abutment of unequal length, prevent the adverse condition of reverse installation of sliding block, effectively solve the adverse phenomenon of "KATA"
noise.
