Cylinder and compression assembly of a rotary compressor having the same

Abstract

The invention discloses a cylinder and a compression assembly of a rotary compressor with the same. The cylinder includes: an outer cylinder body and an inner cylinder body, the inner cylinder body is arranged on the inner side of the outer cylinder body, a connecting cylinder body is arranged between a part of the inner cylinder body and the outer cylinder body, and a connecting cylinder body is arranged between the outer cylinder body, the inner cylinder body and the connecting cylinder body A liquid storage chamber is defined between them, and reinforcing ribs are connected between the outer cylinder body and the inner cylinder body, wherein the height of the cylinder is H, and the maximum axial dimension of the reinforcing ribs is h, and 0.15*H≤h<H. According to the cylinder of the embodiment of the present invention, the overall rigidity of the cylinder can be improved, and the large deformation of the cylinder due to the large gas pressure difference can be avoided, so as to ensure the tightness between the cylinder and the connected parts, and thus ensure the tightness and reliability of the compressor. . At the same time, it can effectively reduce the suction pressure loss, improve the suction flow channel, and improve the energy efficiency of the compressor. The structure of the cylinder is simple and reasonable, which is beneficial to reduce the overall volume of the compressor. The limitation of the height of the ribs can ensure a better combination between the outer cylinder and the inner cylinder.

Description
