Abstract
The utility model relates to the field of automobile air conditioning compressor manufacturing, in particular to a cylinder body used for a variable displacement automobile air conditioning compressor. The cylinder body used for the variable displacement automobile air conditioning compressor comprises a cylinder body and is characterized in that a Teflon layer 2 is arranged on the inner wall of a piston hole inside the cylinder body 1. Compared with the prior art, the cylinder body used for the variable displacement automobile air conditioning compressor removes the assembling process of a piston ring, saves assembly time, and meanwhile, improves air tightness and adiabaticity of the cylinder body, and therefore the refrigeration performance of the compressor is improved, and the comprehensive performance of the compressor is greatly improved.
Description
Technical field
The utility model relates to automobile air conditioner compressor and manufactures field, specifically a kind of cylinder block for variable displacement automobile air-conditioning compressor.
Background technique
At present, a compressor need to assemble 12 to 14 piston rings, and the installation time is long, also needs material department that piston ring is delivered on the hookup wire before the assembling, and is unfavorable for enhancing productivity.The material of cylinder block is aluminium, material itself is comparatively soft, and long-time interference fit between the piston ring, the wearing and tearing of cylinder block piston hole are larger, simultaneously, cylinder block itself also has little trachoma and pore produces, if control impolitic words, leak phenomenon in can producing, have a strong impact on the refrigeration performance of compressor.Gas compresses in the cylinder block piston hole, and this process is not to be adiabatic process, decreases for the efficient of refrigeration performance, has affected the overall performance of compressor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, is provided with the Teflon layer at cylinder block piston hole inwall, and the piston ring of cancellation on the piston directly and the piston interference fit, finished the process of gas compression.
For achieving the above object, design a kind of cylinder block for variable displacement automobile air-conditioning compressor, comprised the cylinder block body, it is characterized in that: on the inwall of the intrinsic piston hole of cylinder block, be provided with one deck Teflon layer.
Model utility is compared with prior art, and the assembly process of cancellation piston ring has been saved installation time, simultaneously, improve the tightness of cylinder block, improved the adiabaticity of cylinder block, can improve like this refrigeration performance of compressor, greatly improve the combination property of compressor.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Referring to Fig. 1 and Fig. 2,1 is the cylinder block body; 2 is the Teflon layer.
Embodiment
Now by reference to the accompanying drawings the utility model is described further.
Referring to Fig. 1 and Fig. 2, the utility model mainly comprises the cylinder block body, it is characterized in that: on the inwall of the piston hole in cylinder block body 1, be provided with one deck Teflon layer 2.The piston ring of cancellation on the piston directly and the piston interference fit, finished the process of gas compression.Save installation time, simultaneously, improved the tightness of cylinder block, improved the adiabaticity of cylinder block, can improve like this refrigeration performance of compressor, greatly improved the combination property of compressor.
Claims (1)
1. a cylinder block that is used for variable displacement automobile air-conditioning compressor comprises the cylinder block body, and it is characterized in that: the inwall of the piston hole in cylinder block body (1) is provided with one deck Teflon layer (2).
