Abstract
The utility model relates to a high-pressure oil spraying type sealing piston which comprises a piston, a cylinder body and a piston ring and is characterized in that the outer cylindrical surface of the piston is provided with an oil guide groove; the oil guide groove is provided with an oil inlet hole in a run-through manner; and the high-pressure oil spraying type sealing piston is connected with a high-pressure oil spraying system by a high-pressure hose.
Description
Technical field
The sealing configuration of the utility model and a kind of engine piston, specifically a kind of high pressure fuel injector formula packed-piston.
Background technique
At present, conventional engines piston is by piston ring packing, due to and cylinder body between to do continuous relative displacement, so inevitable gapped between piston ring and cylinder body, cause the acting gas leakage of high pressure, engine efficiency is declined.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of high pressure fuel injector formula packed-piston.
In order to solve the problems of the technologies described above, high pressure fuel injector formula packed-piston of the present utility model, comprises piston, cylinder body, piston ring, is characterized in that, on the outer cylinder of piston, be provided with oil guide slot, in oil guide slot, connect oil inlet hole is set, by high pressure hose, connect high pressure fuel injector system.
Described oil guide slot is arranged on the piston cylinder being positioned at below piston ring.
Adopt the design's beneficial effect to be: by high pressure oil pump, constantly in piston oil guide slot, to pump into high pressure oil, make the gap between oily injection into pistion and cylinder body, owing to being up subject to the obstruction of piston ring.High pressure oil only has by the gap below piston ring and sprays outward high pressure oil, and the gap between piston and cylinder body forms a high pressure resistant oil film, thereby effectively stops the leakage of high-pressure gas, improves engine efficiency.
Accompanying drawing explanation
Fig. 1 is the structure sectional view of high pressure fuel injector formula packed-piston of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, high pressure fuel injector formula packed-piston of the present utility model is described in further detail.
As shown in the figure, high pressure fuel injector formula packed-piston of the present utility model, comprises piston 1, cylinder body 2, piston ring 3, is characterized in that, on the outer cylinder of piston 1, be provided with oil guide slot 4, in oil guide slot 4, connect oil inlet hole 5 is set, by high pressure hose 6, connect high pressure fuel injector system 7.
Described oil guide slot 4 is arranged on and is positioned on the piston cylinder of piston ring below 3.
