A rotary cylinder piston compressor

Abstract

The invention provides a rotating cylinder piston compressor. The rotating cylinder piston compressor comprises an air cylinder sleeve (1), an air cylinder (2) arranged in the air cylinder sleeve (1) and a piston (3); a round piston hole (22) penetrating the air cylinder (2) is arranged on the air cylinder (2) in a manner of being perpendicular to the axis direction of the air cylinder (2), and the piston (3) is arranged in the piston hole (22) in a manner of being matched in shape; a first groove (21) is formed in the inner wall of the piston hole in the axial direction of the piston hole, and a guide limiting piece (4) is arranged on the side wall of the piston (3); and when the piston (3) and the air cylinder (2) are assembled, the guide limiting piece (4) is assembled in the first groove (21) in a sliding manner. By means of the rotating cylinder piston compressor, autoroatation of the piston can be prevented, furthermore, interference even air cylinder collision between the head of the piston and the inner circle of the air cylinder can be prevented from occurring, a fit clearance between the piston and the piston sleeve can be effectively guaranteed, the assembling performance of the compressor is improved accordingly, and the efficiency of the compressor is improved.

Description

technical field [0001] The invention belongs to the technical field of compressors, in particular to a rotary cylinder piston compressor. Background technique [0002] The rotary cylinder piston compressor based on the principle of the cross slider includes a cylinder liner, a cylinder and a piston, wherein the cylinder can rotate in the cylinder liner, and the piston is horizontally arranged in the piston hole of the cylinder, and can slide reciprocally in the piston hole, so that A compression chamber is formed between the end face of the piston, the side wall of the piston hole and the inner wall of the cylinder liner. [0003] In order to ensure the degree of fit between the piston and the piston hole, from a manufacturing point of view, it is obviously the most economical to use a circular piston hole and a piston with a cylindrical cross-section, and it is also the easiest to ensure accuracy. However, in this case, since the piston hole is arranged laterally in the cy...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to overcome the situation that the rotary cylinder piston compressor in the prior art either has the piston self-rotating, which causes the piston head to interfere with the inner wall of the cylinder liner or even hit the cylinder, or the cooperation gap between the piston and the piston liner Defects that affect the assembly and performance of the compressor are not good, so as to provide a rotary cylinder piston compressor that can prevent the piston from rotating
