Compressor roller, compressor pump body and compressor

Abstract

The invention provides a compressor roller, a compressor pump body and a compressor. The compressor roller comprises a cylindrical roller main body, and an inner flange arranged at a first end of the roller main body. Under the condition of satisfying the sealing requirement of a compression cylinder, the displacement of the compressor can be increased, so that the displacement of the compressor reaches the highest theoretical displacement.

Description

technical field [0001] The invention relates to the technical field of air conditioning, and more specifically, to a compressor roller, a compressor pump body and a compressor. Background technique [0002] see figure 1 As shown, in the existing two-cylinder compressor with single cylinder and single exhaust and the exhaust structure is the upper and lower flange exhaust, considering the generalization of the use of parts, compressors using the same compression cylinder 3 with different displacements will use the same Upper flange 2. At the same time, considering the smoothness and resistance of the exhaust, the upper flange 2 is provided with an exhaust hole 1, and the distance between the exhaust hole 1 and the center line of the upper flange 2 will not be too far or too close. The same goes for size. [0003] For details, see figure 2 and image 3 shown in figure 2 Among them, d1 is the inner diameter of the compression cylinder 3, d2 is the diameter of the roller...

AI Technical Summary

Problems solved by technology

[0005] According to the above content, it can be known that due to the restriction of the minimum length of the sealing belt L1 between the inner diameter of the roller 4 and the exhaust hole 1, the eccentricity of the crankshaft 5 cannot reach the theoretical maximum value, resulting in the use of a compressor with a fixed compression cylinder 3 The maximum displacement is generally less than the theoretical maximum displacement
