Abstract
A kind of anti-air-following oil drain top surface punching piston, including: piston main body, groove is carved on piston main body, the design of piston main body top surface has through-hole, one end aperture of through-hole is in the top surface of piston main body, and for another end opening of through-hole in groove, the through-hole is corresponding in the position of piston main body top surface and the position of groove, number of recesses be it is multiple, number of openings be it is multiple.The utility model has the advantages that: the utility model is in use, grease lubrication is needed because air compressor piston does the piston ring in reciprocation type movement on piston and generates to rub with inner wall of cylinder, lubricant grease stays product in piston-top surface after long-play, then lubricant grease is pushed back from through hole by groove by compressed gas, it is recovered to box house, so that the generation for effectively controlling air-following oil drain phenomenon extends air compressor machine service life.
Description
Technical field
The utility model is to be related to vehicle-mounted air compressor and toward trans- air compressor machine accessory, concretely relate to anti-air-following oil drain
Punch piston in top surface.
Background technique
Piston ring and inner wall of cylinder generation friction needs in reciprocation type movement on piston are done in existing air compressor piston
Grease lubrication, and lubricant grease stays product that cannot can follow compression back on the contrary in cabinet in piston-top surface after long-play
Gas is discharged simultaneously from causing air-following oil drain quantity to increase, and wastes lubricating oil, pollutes environment.
Summary of the invention
The purpose of the utility model is to overcome deficiencies in the prior art, provide one kind effectively the intracorporal profit of cylinder
Lubricating oil rouge is recovered in cabinet, to solve the problems, such as that the air-following oil drain quantity of existing product increases, increases the service life of product
Punch piston in anti-air-following oil drain top surface.
In order to solve the above-mentioned technical problem, the present invention is achieved through the following technical solutions:
A kind of anti-air-following oil drain top surface punching piston, including: piston main body, it is characterized in that: the piston master
Groove is carved on body, the piston main body top surface design has through-hole, and one end aperture of through-hole is in the top surface of piston main body, through-hole
Another end opening in groove, the through-hole is corresponding in the position of piston main body top surface and the position of groove.
Piston is punched according to above-mentioned anti-air-following oil drain top surface, it is characterized in that: the number of recesses is multiple.
Piston is punched according to above-mentioned anti-air-following oil drain top surface, it is characterized in that: the number of openings is multiple.
The utility model has the advantages that: the utility model in use, because air compressor piston do reciprocation type movement in
Piston ring and inner wall of cylinder on piston generate friction and need grease lubrication, and lubricant grease stays product in piston after long-play
Then lubricant grease is pushed back groove from through hole by compressed gas, is recovered to box house by top surface, so that effectively control is with gas
The generation of oil extraction phenomenon extends air compressor machine service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the top view of Fig. 1.
In attached drawing
1, piston main body 2, groove 3, through-hole.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
A kind of anti-air-following oil drain top surface punches piston, as shown in Figure 1, 2, including piston main body 1, on piston main body 1
It is carved with groove 2,1 top surface of the piston main body design has through-hole 3, and one end aperture of through-hole 3 is led in the top surface of piston main body 1
For another end opening in hole 3 in groove 2, the through-hole 3 is corresponding with the position of groove 2 in the position of 1 top surface of piston main body.
In the present embodiment, 2 quantity of groove is multiple.
In the present embodiment, 3 quantity of through-hole is multiple.
The beneficial effects of the utility model are:
The utility model in use, because air compressor piston does the piston ring and cylinder barrel in reciprocation type movement on piston
Inner wall generates friction and needs grease lubrication, and lubricant grease stays product in piston-top surface after long-play, then by compressed gas
Groove is pushed back from through hole by lubricant grease, is recovered to box house, so that the generation for effectively controlling air-following oil drain phenomenon extends
Air compressor machine service life.
Undeclared part involved in the utility model is same as the prior art or is realized using the prior art.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel conception and scope of protection are defined, without departing from the design concept of the present utility model, common in this field
The all variations and modifications that engineers and technicians make the technical solution of the utility model should all fall into the guarantor of the utility model
Protect range.
