Problems solved by technology

[0019] However, the above-mentioned existing rotary vane compressor has the following disadvantages: since the above-mentioned existing rotary vane compressor sucks the gaseous refrigerant from the side of the cylinder 4, it is relatively difficult to suck the gaseous refrigerant into the inner compression chamber of the annular blade 51. Difficulty, not only the suction loss of gaseous refrigerant, in order to overcome this loss, it is necessary to improve the compression device
[0020] In addition, due to the pressure difference between the suction pressure and the discharge pressure, the slider clings excessively to the end of the annular vane on the suction side, causing friction loss, which will reduce the compression efficiency and the reliability of the compressor

Abstract

The rotary vane compressor has a ring vane running space inside the cylinder, an enclosed round structure formed by one side of the running space with sealing components. Both ends of two sides of the running space have side suction inlet and exhaust inside and outside respectively. The reserved gap between the end of one side of a suction inlet of a ring vane and the end of the running space makes the formation of a suction channel between the end of the ring vane and the end of the running space. With the affect of the air proof mechanism at the end of the ring vane's exhaust, a sealing is formed between the inside and outside compressing chambers. With the smoother running of gaseous cooling agent into the inside compressing chamber of the ring vanes, it avoids the abrasion caused by too tight contacting of sliders and vanes and improves the compressing efficiency and reliability of the compressor.

Description

technical field [0001] The invention relates to a compressor, in particular to a compression device of a rotary vane compressor. Background technique [0002] Figure 1 is a longitudinal sectional view of the overall structure of an existing common rotary vane compressor; as shown in Figure 1, the existing common rotary vane compressor forms inner and outer compression chambers inside the cylinder through the rotation of the vanes. The compressor shown in FIG. 1 is a low-pressure hermetic rotary compressor used in hermetic refrigerant compressors such as refrigerators and air conditioners. [0003] In the low-pressure sealed rotary compressor, the driving device D and the compressing device P are arranged inside the housing 1; the driving device D and the compressing device P are connected through a crankshaft 8 arranged vertically, and the crankshaft The upper and lower ends of 8 are respectively supported by the main bearing plate 6 and the auxiliary bearing plate 7, and t...
