Abstract

A blade of the compression mechanism for compressor is disclosed. Said compression mechanism is composed of cylinder unit with internal space, rotary axle passing through said internal space and inserted in said cylinder unit, isolating plate integrated with said rotary axle and dividing said internal space into spaces A and B, and the blade axially reciprocating to switch said spaces A and B into sucking area and compression area. Said blade feature is that it has a curved surface for contacting with rotary axle.

Description

1. Technical field: [0001] The invention relates to a compressor blade, in particular to a compressor blade whose shaft contact curved surface part corresponds to the outer peripheral surface of the rotating shaft. 2. Background technology: [0002] Generally speaking, as a mechanism for compressing gas, a compressor is mainly composed of a sealed container with a certain internal space, a transmission mechanism installed in the sealed container to generate driving force, and a compression mechanism driven by the transmission mechanism to compress gas. According to the shape of the compression mechanism, the compressor can be divided into many types, Figure 1-3 Shown is a schematic diagram of a compressor that compresses a refrigerant gas. As shown in the figure, a rotating shaft 20 is provided in the center of the internal space V of the cylinder assembly 10, and the internal space V is provided with a suction flow channel 11 and a discharge flow channel 12. The rotating s...
