Abstract
The utility model provides a compression ring with an external tangential conical surface for an engine piston. The compression ring comprises a ring-type body with an opening, and a circumferential groove arranged at a juncture of the periphery and the side of the ring-type body, wherein a first end face and a second end face are formed at the opening part of the ring-type body, and a first distance between one end of the circumferential groove and the first end face is formed; a second distance between the other end of the circumferential groove and the second end face is formed. The compression ring provided by the utility model can effectively reduce the amount of air leakage of the piston, thereby increasing the work efficiency of an engine.
Description
Technical field
The utility model relates to a kind of piston ring for engine piston, relates in particular to a kind of conical surface circumscribed-type compression ring.
Background technique
As everyone knows, piston ring is that down enters the metal ring in piston groove inside.Piston ring is mainly divided into compression ring and scraper ring.Compression ring can be used to the indoor burning mixture of sealing combustion, and scraper ring is used for striking off machine oil unnecessary on cylinder.
At present, the structure of existing conical surface circumscribed-type (claiming again cut type under the conical surface) compression ring mainly comprises having the annulus body of opening and be configured in periphery on annulus body and the peripheral groove of the intersection of side.Wherein, peripheral groove edge from one end of the opening of annulus body circumferentially extends to the other end.After conical surface circumscribed-type compression ring is arranged between piston and piston cylinder, the opening of conical surface circumscribed-type compression ring can be communicated with the interim circumferential passageway being formed between peripheral groove and piston cylinder, causes having increased piston air leakage, thereby reduces working efficiency.
Model utility content
The purpose of this utility model is to provide a kind of conical surface circumscribed-type compression ring, and it can reduce piston air leakage effectively, thereby increases work efficiency.
The utility model provides a kind of conical surface circumscribed-type compression ring for engine piston, and it comprises: have the circular shape body of opening, circular shape body forms the first end face and the second end face at opening; Be located at the peripheral groove of the periphery of circular shape body and the intersection of side.Wherein, between one end of peripheral groove and the first end face, be formed with the first distance, and be formed with second distance between the other end and the second end face.
In one embodiment, the first distance is configured to 3-5mm.
In one embodiment, second distance is configured to 3-5mm.
In one embodiment, conical surface circumscribed-type compression ring is made of cast iron.
According to conical surface circumscribed-type compression ring of the present utility model, by the first distance and second distance, can effectively reduce opening air leakage, thereby minimizing piston air leakage, can reduce the pressure to the corrosion of machine oil and crankcase thus, be beneficial to piston and externally do work, and then improve the working efficiency of motor.
Accompanying drawing explanation
To the utility model, be described in more detail based on embodiment and with reference to accompanying drawing hereinafter.Wherein:
Fig. 1 schematically illustrates according to the structural representation of conical surface circumscribed-type compression ring of the present utility model.
Fig. 2 schematically illustrates according to the partial enlarged drawing of the opening of conical surface circumscribed-type compression ring of the present utility model.
In the accompanying drawings, identical parts are used identical reference character.Accompanying drawing is not according to actual scale.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 schematically illustrates according to conical surface circumscribed-type compression ring 10 of the present utility model.This conical surface circumscribed-type compression ring 10 can be used the indoor burning mixture of sealing combustion on piston of automobile.
According to conical surface circumscribed-type compression ring 10 of the present utility model, comprise the circular shape body 4 with opening 5.Circular shape body 4 is preferably made of cast iron.Circular shape body 4 forms the first end face 1 and the second end face 2 at opening 5 places.In addition, this conical surface circumscribed-type compression ring 10 also comprises the peripheral groove 3 that is located at the periphery of circular shape body 4 and the intersection of side.Between one end of peripheral groove 3 and the first end face 1, be formed with the first distance 6, and be formed with second distance 7 between the other end and the second end face 2.This first distance 6 and second distance 7 can be clearly shown in Fig. 2.
By lot of experiment validation, when the first distance 6 and second distance 7 are while being all configured to 3-5mm, this conical surface circumscribed-type compression ring 10 reduces the best results of piston air leakage.
According to conical surface circumscribed-type compression ring 10 of the present utility model, by the first distance 6 and second distance 7, can effectively reduce opening 5 place's air leakages, thereby minimizing piston air leakage, can reduce the pressure to the corrosion of machine oil and crankcase thus, be beneficial to piston and externally do work, and then improve the working efficiency of motor.
Although the utility model is described with reference to preferred embodiment, in the situation that not departing from scope of the present utility model, can carries out various improvement and can replace parts wherein with equivalent it.Especially, only otherwise have structural hazard, every technical characteristics of mentioning in each embodiment all can combine in any way.The utility model is not limited to disclosed specific embodiment in literary composition, but comprises all technological schemes in the scope that falls into claim.
