Abstract
The utility model relates to the technical field of machinery, in particular to an automobile air conditioner compressor piston without a piston ring, which comprises a piston body. The automobile air conditioner compressor piston is characterized in that the outer wall of the piston body is in a cylindrical shape, and a layer of Teflon is wrapped outside the piston body. Compared with the prior art, the periphery of the piston is changed into a cylinder body, the piston ring is removed, the periphery of the piston is treated with Teflon, thereby achieving sealing and lubrication simultaneously, reducing cost and improving production efficiency.
Description
Technical field
The utility model relates to field of mechanical technique, is a kind of automobile air conditioner compressor piston that does not have piston ring specifically.
Background technique
Originally each piston of automobile air conditioner compressor adopts 2 piston rings, and a piston ring seals, and another piston ring is lubricated; But often there is piston ring well not to be assembled on the piston; Event needs repeatedly to confirm, when lubricated when not enough, piston ring is easy abrasion extremely; Because piston ring involves great expense, so increased cost and manpower.
Summary of the invention
The utility model is the deficiency that overcomes existing technology, and the structure that changes piston only is cast out piston ring, has so not only reduced cost but also has saved manpower.
For realizing above-mentioned purpose, design a kind of automobile air conditioner compressor piston that does not have piston ring, comprise piston only, it is characterized in that: the outer wall of piston only is cylindric, and outside piston only, covers one deck Teflon.
The utility model is compared with existing technology, and the piston periphery is transformed into cylindrical body, has cast out piston ring, and does Teflon at the piston periphery and handle, and has so not only accomplished sealing but also accomplished to lubricate, and kills two birds with one stone, and reduces cost, and enhances productivity.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model structure worm's eye view.
Embodiment
According to accompanying drawing the utility model is done further explanation below.
As shown in Figure 1, original piston is removed piston groove, be transformed into its outer wall and be cylindric; And at 1 external one deck Teflon 2 that covers of piston, this Teflon 2 has heat resistance, wear resistance, characteristics such as corrosion-resistant, fully can replacing piston ring; Not only accomplished sealing but also accomplished lubricated; Kill two birds with one stone, reduce cost, enhance productivity.
Claims (1)
1. an automobile air conditioner compressor piston that does not have piston ring comprises piston only, it is characterized in that: the outer wall of piston (1) body is cylindric, and outside piston only (1), covers one deck Teflon (2).
