Abstract
The invention relates to a piston of an automobile air compressor. The piston comprises a piston body, a first air ring groove, a second air ring groove and an oil ring groove, wherein the first air ring groove, the second air ring groove and the oil ring groove are formed in the outer circle of the upper end of the piston body; the second air ring groove is formed between the first air ring groove and the oil ring groove; the oil ring groove is formed in the middle part of the piston body; a chamfer is arranged at the bottom of the oil ring groove. The chamfer is arranged at the bottom of the oil ring groove, so that an oil ring is used for scraping oil when the piston moves downwards and the oil is stored in the chamfer, and furthermore, the oil returning effect is good and the oil is prevented from moving in the air compressor.
Description
Technical field
The present invention relates to a kind of piston of automobile air compressor.
Background technique
The piston that existing automobile air compressor uses, oil return effect is bad, and air compressor easily alters oil, does not meet environmental requirement.And material therefor is mainly ZL108, be difficult to meet mechanical property, high-temperature behavior, the technical requirements of the aspect products such as piston face quality.
Summary of the invention
Technical problem to be solved by this invention is to provide the effective piston of automobile air compressor of a kind of oil return.
The technological scheme that the present invention solves the problems of the technologies described above is as follows: a kind of piston of automobile air compressor, comprise piston body, first gas ring groove, second gas ring groove and oil ring groove, described first gas ring groove, second gas ring groove and oil ring groove are all located on the upper end cylindrical of described piston body, described second gas ring slot is between described first gas ring groove and described oil ring groove, described oil ring groove is positioned at the intermediate portion of described piston body, and the bottom of described oil ring groove is provided with a chamfering.
The invention has the beneficial effects as follows:
The bottom of oil ring groove of the present invention is provided with a chamfering, and when the piston is moving down, oil ring frizing, be stored in by oil in chamfering, thus oil return is effective, can reduce air compressor and alter oil.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described chamfer dimesion is 0.5 ~ 1mm.
Accompanying drawing explanation
Fig. 1 is the structural representation of piston of automobile air compressor of the present invention;
In accompanying drawing, the list of parts representated by each label is as follows:
1, piston body, 2, first gas ring groove, 3, second gas ring groove, 4, oil ring groove, 5, chamfering.
Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
A kind of piston of automobile air compressor, as shown in Figure 1, comprise piston body 1, first gas ring groove 2, second gas ring groove 3 and oil ring groove 4, described first gas ring groove 2, second gas ring groove 3 and oil ring groove 4 are all located on the upper end cylindrical of described piston body 1, described second gas ring groove 3 is between described first gas ring groove 2 and described oil ring groove 4, described oil ring groove 4 is positioned at the intermediate portion of described piston body 1, and the bottom of described oil ring groove 4 is provided with a chamfering 5.
Described chamfering 5 is of a size of 0.5 ~ 1mm.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
