Problems solved by technology

[0005] However, in the structure of the above-mentioned document 2, since the high-pressure chamber and the low-pressure chamber are formed adjacent to the upper and lower sides of the compression member (swash plate) in the entire cylinder, the efficiency is low due to the increase of the high-pressure and low-pressure differences. The problem
[0006] In addition, the cylinder and the compression member rotating in the cylinder are made of the same material and processed in the same way, and their hardness is the same. Therefore, wear is likely to occur due to the friction of rotation, and there is a problem that the durability of the compression member is poor.
[0007] In addition, among compressors having a structure like the above document 2, there is no so-called non-lubricated compressor that does not use oil such as lubricating oil.

Abstract

The invention provides a compressor, which can improve the durability of a compression component, realize that the reliability of the compressor is increased, and ensure the sliding property to be good even if a compression element has no lubrication. The compressor has the compression element, a suction port, an exhaust port, the compression component and blades; wherein, the compression element is composed of a cylinder which forms a compression space in the interior, the suction port and the exhaust port are communicated with the compression space in the cylinder, the compression component and one surface which is axially crossed with a rotating shaft are slant between an upper dead center and a lower dead center in a continuous way; at the same time, the compression component is arranged in the cylinder and is driven by the rotating shaft to rotate, liquid (cooling medium) sucked in from the suction port is compressed and discharged from the exhaust port, and the blades which divide the compression space in the cylinder into a low pressure chamber and a high pressure chamber are arranged between the suction port and the exhaust port, and are contacted with the top of one surface of the compression component. The compressor has the advantages that the rigidity at the upper side of the compression component is higher than that of a discharging part which is taken as the bearing surface of the upper dead center and lower than that of the blades.

Description

technical field [0001] The present invention relates to a compressor for compressing and discharging fluids such as refrigerant and air. In particular, it relates to a compressor capable of ensuring good sliding properties even when the compression element is non-lubricated. Background technique [0002] Until now, for example, in refrigerators, a method in which a compressor compresses a refrigerant and circulates the refrigerant in a circuit is used. Examples of such compressors include a rotary compressor called a rotary compressor (JP-A-5-99172, Document 1), a scroll compressor, and a screw compressor. [0003] The above-mentioned rotary compressor has the advantages of relatively simple structure and low manufacturing cost, but has the problems of large vibration and torque fluctuation. In addition, scroll compressors and screw compressors have problems of difficulty in processing and high cost, although torque variation is small. [0004] Therefore, as shown in Japa...
