Abstract
The utility model provides an efficient engine piston, belongs to the technical field of air cylinders and pistons of combustion engines, and particularly relates to a piston for a diesel engine or a gasoline engine. The efficient engine piston aims to solve problems and overcomes defects in the prior art, and is simple in structure, capable of effectively reducing engine air leakage, good in impact force resistance and wearable. The efficient engine piston comprises a piston body, wherein air ring grooves and an oil ring groove are formed in the piston body in the radial direction. The efficient engine piston is characterized in that at least two piston rings are arranged in each air ring groove, an opening is formed in each piston ring, and the openings of two adjacent piston rings are arranged in a staggered mode.
Description
Technical field
the utility model belongs to cylinder, the piston technical field of combustion engine, particularly, relates to the piston that a kind of diesel oil, petrol engine are used.
Background technique
china Patent No. is: 200520093906.9, name is called: piston type diesel, petrolic air tight piston disclose a kind of piston for engine, be characterized in: comprise piston, in each compression on piston, be provided with the piston ring that two openings stagger.Owing to being provided with the piston ring that two openings stagger in each compression on its piston, therefore, just can effectively avoid gas to overflow from piston opening, improve the working efficiency of motor.
yet in actual applications, still there are the following problems for above-mentioned patent: owing to only there being two piston rings in each compression in this patent, so between two-piston ring, the effect of sealing is not good enough relatively; In addition, because piston ring has opening, at work, pressurized gas in cylinder have part to spill from opening, after using a period of time, because of piston ring and cylinder friction, can make gap-clearance of piston rings become large, the pressurized gas that spill increase, and have reduced the working efficiency of motor.
Summary of the invention
the utility model is exactly for the problems referred to above, overcomes the deficiency that prior art exists, provide a kind of simple in structure, can effectively reduce motor gas leakage, anti-impact force performance is good, and wear-resisting engine piston.
for realizing above-mentioned purpose of the present utility model, the utility model adopts following technological scheme.
the utility model comprises piston, and the footpath of piston is upwards provided with compression and oil ring ditch, and its structure outline is: in described compression, be provided with at least two piston rings, have opening on piston ring, the interleaved openings of adjacent two-piston ring is arranged.
further, can in described compression, be fixedly installed the piston ring block corresponding with gap-clearance of piston rings.
the beneficial effects of the utility model compared with prior art.
high efficience motor piston of the present utility model on the basis of existing technology, increased the quantity of piston ring, and in compression, be provided with the piston ring block corresponding with gap-clearance of piston rings, not only simple in structure, prevent piston ring play when pistons work, cause the opening of adjacent pistons ring to overlap; And at least two or more piston rings can better seal opening mutually, effectively prevent that pressurized gas from leaking from opening, thereby improve the efficiency of motor, and the anti-impact force performance that can also improve piston ring.
Accompanying drawing explanation
fig. 1 is structural representation of the present utility model.
fig. 2 is the structural representation that Fig. 1 takes off piston ring.
fig. 3 is the structural representation of the utility model piston ring.
in figure, 1 is that oil ring ditch, 2 is that piston ring, 3 is that piston ring block, 4 is that piston, 5 is that compression, 6 is opening.
Embodiment
the utility model comprises piston 4, and the footpath of piston 4 is upwards provided with compression 5 and oil ring ditch 1, is provided with at least two piston rings 2 in described compression 5, has opening 6 on piston ring 2, and the opening 6 of adjacent two-piston ring 2 is staggered.
in described compression 5, be fixedly installed the piston ring block 3 corresponding with piston ring 2 openings 6.
through practical proof, for high power engine, two or three compressions 5 can be set conventionally, and can adopt three piston rings 2 in each compression 5; For low power motor, a compression 5 can be only set, and can adopt three piston rings 2 in each compression 5.
be understandably, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technological scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; As long as meet, use needs, all within protection domain of the present utility model.
