A piston limiting structure, including: a cylinder, a piston, and a flange provided with a limiting piece, the cylinder has a piston hole perpendicular to an axial direction of the cylinder and penetrating through the cylinder, and a projection of the piston hole in a penetrating direction is circular. The piston is disposed in the piston hole in a form-fit manner and is slid in the piston hole in a reciprocating manner. A side wall of the piston is provided with a thrust groove, a bottom surface of the thrust groove forms a thrust surface on the side wall of the piston, and the thrust groove does not penetrate through two ends of the side wall of the piston along an axial length of the piston. The limiting piece abuts against the thrust surface.

Piston limiting structure, compressor, and heat exchange apparatus

Some embodiments of a disclosure provide a piston limiting structure, a compressor, and a heat exchange apparatus. The piston limiting structure includes: a cylinder, having a piston hole perpendicular to an axial direction of the cylinder and penetrating the cylinder, wherein a projection of the piston hole in a penetrating direction is circular; a piston, disposed in the piston hole and slid in the piston hole, wherein a side wall of the piston is provided with a limiting surface, and the limiting surface does not penetrate two ends of the side wall of the piston along an axial length of the piston; and a limiting member, wherein the cylinder is provided with a limiting hole penetrating from an outer wall of the cylinder to the piston hole, the limiting member is mounted in the limiting hole, and the limiting member abuts against the limiting surface.
