Embodiment Construction

[0013] The present invention is described by way of example with reference to the accompanying drawings, in which like parts are denoted by like numerals.

[0014] Figure 1a , 1b , 1c is a schematic diagram of the cylinder of the present invention. The lateral force acts on the vertical plane (equivalent to the inner wall of the cylinder), such as Figure 1a , when the applied force increases, the plane deforms elastically, and the lateral force received is decomposed into the force parallel to the inclined plane and the force perpendicular to the inclined plane, as Figure 1b , to relieve the effect of the lateral force on the plane, and after the force is weakened, the deformed plane returns to a vertical plane, such as Figure 1c .

[0015] According to the above principle, figure 2 Shown is the cylinder 10 of the present invention, wherein a flexible hinge mechanism is provided circumferentially on the end face of the cylinder on the side of the high pressure chamber....

Abstract

The invention discloses a cylinder for a rotary type compressor. A flexible hinge mechanism capable of generating elastic deformation is arranged on the end face of the high-pressure cavity side of the cylinder and is used for reducing the force acting on a crankshaft. According to the cylinder for the rotary type compressor, the phenomenon of eccentric wear of an eccentric circle of the crankshaft can be effectively reduced, the performance of the rotary compressor is improved, and the service life is prolonged. The invention also provides the rotary type compressor.

Description

technical field [0001] The present invention relates to a cylinder for a rotary compressor and a rotary compressor including the cylinder. Background technique [0002] When the rotary compressor is working, the crankshaft drives the rotor to rotate at high speed, sucks air from the outside, compresses the sucked gas to make it a high-pressure gas, and then discharges it. During this process, the inner wall of the cylinder on the side of the high-pressure chamber has been subjected to the high-pressure action of the high-pressure gas. This force cannot be buffered, and finally produces a huge reaction force on the crankshaft, which is likely to cause the crankshaft to tilt, resulting in increased winding when the crankshaft is running at high speed. Eccentric wear occurs, which leads to low energy efficiency and short service life of the compressor. Contents of the invention [0003] Aiming at the above-mentioned problem that the cylinder in the existing rotary compressor...
