Technical field
The present invention relates to gas machine field, particularly a kind of oil seal ring of gas machine piston.
Background technique
At present, the demand reducing the friction power loss of motor is more strong, and the engine oil consumption simultaneously reducing motor is also when previous heat topic.
But with regard to piston and piston ring prior art aspect, a lot of technology all can not allow above 2 demands get both, and all can not meet: " while not affecting frictional work or engine oil consumption, effectively can reduce engine oil consumption or friction work." requirement.Such as: can engine oil consumption be reduced by improving piston ring elastic force, but just improve friction power loss; Can reduce frictional work by reducing piston ring elastic force, corresponding engine oil consumption can affect again to some extent.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of oil seal ring of simple and reasonable gas machine piston, the oil seal ring of this gas machine piston adopts to set up on grommet and unloads oilhole, the machine oil scraped to increase scraping ring falls path after rise, engine sump tank is flowed back to by unloading oilhole, the remaining machine oil of effective reduction cylinder liner surface, reduce consumptions of burning because machine oil too much remains in cylinder surface, under the prerequisite of existing friction power loss not affecting motor, while effectively can reduce again the engine oil consumption of motor.
For achieving the above object, the invention provides the oil seal ring of gas machine piston, comprise: grommet, it comprises: supporting body, spacing preiection and unload oilhole, described supporting body is concavo-convex folding circular, described spacing preiection is distributed in the inner side of each concavo-convex summit of supporting body, and the outside of the concavo-convex summit of described supporting body forms scraping ring attachment face; The described oilhole that unloads is opened between described supporting body and spacing preiection; And a pair scraping ring, be laid on the scraping ring attachment face of described supporting body respectively, the inner side of this scraping ring abuts spacing with described spacing preiection.
Preferably, in technique scheme, supporting body has an opening.
Preferably, in technique scheme, spacing preiection semicircular in shape or rectangle.
Preferably, in technique scheme, unload oilhole semicircular in shape or rectangle.
Compared with prior art, the present invention has following beneficial effect: the oil seal ring of this gas machine piston adopts to set up on grommet and unloads oilhole, the machine oil scraped to increase scraping ring falls path after rise, engine sump tank is flowed back to by unloading oilhole, the remaining machine oil of effective reduction cylinder liner surface, reduce consumptions of burning because machine oil too much remains in cylinder surface, under the prerequisite of existing friction power loss not affecting motor, while effectively can reduce again the engine oil consumption of motor.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figures 1 to 7, according to specifically comprising of the oil seal ring of the gas machine piston of the specific embodiment of the invention: grommet 1 and be laid in a pair scraping ring 5 of these grommet about 1 both sides respectively, wherein, offer between the supporting body 2 of grommet 1 and spacing preiection 4 and unload oilhole 3, during piston ring work, scraping ring 5 leaves on supporting body 2, inner side is by spacing preiection 4, scraping ring 5 is limited in the both sides up and down of grommet 1 by outside effectively by cylinder liner, when engine piston is descending, tightly be attached to cylinder-barrel surface outside scraping ring 5, scrape the inboard wall of cylinder liner machine oil of lubrication.Oilhole 3 is unloaded because this patent devises cleverly on grommet 1, the machine oil falling path that scraping ring 5 scrapes can be increased, engine sump tank is flowed back to by unloading oilhole, the remaining machine oil of effective reduction cylinder liner surface, reduce consumption of burning because machine oil too much remains in cylinder surface, under the prerequisite of existing friction power loss not affecting motor, effectively can reduce again the engine oil consumption of motor simultaneously.
Specifically, as shown in Figures 4 to 7, grommet 1 comprises: supporting body 2, spacing preiection 4 and unload oilhole 3.Wherein, supporting body 2 in concavo-convex folding circular, and have and only has an opening, has certain tension force after making grommet 1 be pressed into cylinder liner in radial direction.Spacing preiection 4 is distributed in the inner side of each concavo-convex summit of supporting body 2, and spacing preiection 4 entirety is positioned at inside the ring body of grommet 1.The shape of spacing preiection 4 can semicircular in shape or rectangle, and when a pair scraping ring 5 is laid in these grommet about 1 both sides respectively, spacing by spacing preiection 4 inside it, scraping ring 5 is limited in the both sides up and down of grommet 1 by outside effectively by cylinder liner.Unloading oilhole 3 is opened between supporting body 2 and spacing preiection 4, and its shape, can semicircular in shape or rectangle with spacing preiection 4.
Scraping ring 5 is a pair, is laid in this grommet about 1 both sides respectively, and the inner side of scraping ring 5 is undertaken spacing by spacing preiection 4, and the outside of scraping ring 5 is undertaken spacing by cylinder liner.
During piston ring work, scraping ring 5 leaves on supporting body 2, and inner side is by spacing preiection 4, scraping ring 5 is limited in the both sides up and down of grommet 1 by outside effectively by cylinder liner, when engine piston is descending, outside scraping ring 5, be tightly attached to cylinder-barrel surface, scrape the inboard wall of cylinder liner machine oil of lubrication.Oilhole 3 is unloaded because this patent devises cleverly on grommet 1, the machine oil falling path that scraping ring 5 scrapes can be increased, flowing back to engine sump tank by unloading oilhole 3, effectively reducing the remaining machine oil of cylinder liner surface, namely reduce consumption of burning because machine oil too much remains in cylinder surface.
To sum up, the oil seal ring of this gas machine piston adopts to set up on grommet and unloads oilhole, the machine oil scraped to increase scraping ring falls path after rise, engine sump tank is flowed back to by unloading oilhole, the remaining machine oil of effective reduction cylinder liner surface, reduce consumptions of burning because machine oil too much remains in cylinder surface, under the prerequisite of existing friction power loss not affecting motor, while effectively can reduce again the engine oil consumption of motor.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
