Abstract
The invention discloses a piston ring, comprising a cock body (1) and a gap (2), wherein a first end part (A) and a second end part (B) of the cock body (1) are respectively arranged at two sides of the gap (2), a first sealing notch (3) is formed on the outer upper end of the first end part (A), a sealing flange (4) corresponding to the sealing notch (3) is arranged on the outer upper end of the second end part (B), and when the piston ring is arranged in a piston groove (11) on the outer wall of a piston (10), the sealing notch (3) and the sealing flange (4) are matched with each other so as to seal air in an air cylinder. According to the piston ring disclosed by the invention, the effect of the piston ring on sealing the air in the air cylinder of an internal combustion engine is increased; meanwhile, the piston ring cannot get stuck due to high-temperature expansion.
Description
Technical field
The present invention relates to a kind of piston ring, particularly be installed on the piston ring in the cylinder of internal combustion engine piston.
Background technique
For a long time, the research emphasis of internal-combustion engine is how to improve its working efficiency, reduces fuel consumption, prolongs its working life.Piston ring is to keep the bubble-tight strength member of cylinder of internal combustion engine, for keeping effective pressure and fuel oil heat energy utilization rate aspect in the cylinder to play a key effect.Piston ring needs based on installation and avoids metal heated expansion, causes the increase of piston ring external diameter and possibly cause the former of stuck two aspects of piston ring thereby be designed to have fully that the structure and the opening of the opened gap of disconnection are these two kinds of forms of semi-closed structure that convex-concave ladder mouth formula overlaps each other.
In the time of in piston ring is installed to the piston groove on the piston, still leave intercommunication opened gap passage up and down on the piston ring, or through transverse opening gap, piston ring top-piston ring dorsal part gap-piston ring below transverse opening clearance channel.When internal combustion engine, the gas in the cylinder can leak downwards through the opened gap of piston ring, and simultaneously, the gas of entering opened gap can also pass through the dorsal part gap of piston ring and leak downwards the side clearance of below.In compression stroke; Gas in the cylinder can also get into the dorsal part gap through the piston ring side clearance of top; Leak downwards the side clearance that gets into piston ring gap and below again; Make the gas in the part cylinder in compression stroke and power stroke, leak like this, thereby reduced fuel oil heat energy utilization rate and combustion engine powered.Along with the prolongation of internal combustion engine time, the otch of piston ring can be along with the wearing and tearing of piston ring external diameter and cylinder inner wall progressively increases, and makes the gas leak in more cylinders and causes the further reduction and the combustion engine powered obvious decline of fuel oil heat energy utilization rate.
Summary of the invention
The object of the present invention is to provide the improved piston ring of a kind of end, improving the ability of gas in its sealing cylinder, thereby improve the heat energy utilization rate of internal-combustion engine and the working life of internal-combustion engine.
Piston ring of the present invention; Comprise cock body and gap, the both sides in gap are respectively the first end and the second end of cock body, have a seal recess in the outer upper end of first end; Be provided with in the outer upper end of second outer end one with the corresponding sealing flange of seal recess; When piston ring was installed in the piston groove on the piston outer wall, seal recess and sealing flange mated each other, with the gas in the sealing cylinder.
Piston ring of the present invention; Wherein be provided with the push stopping part that an arc stretches out the seal recess front end in the inner of first end; Have one in the inner of second outer end and end recess with the corresponding card of push stopping part; When piston ring was installed in the piston groove on the piston outer wall, push stopping part was ended recess with card and is mated each other.
Piston ring of the present invention; Wherein when this piston ring is installed in the piston groove on the piston outer wall; Push stopping part and card only leave first gap between the recess; Leave second gap below seal recess and the sealing flange, leave third space between seal recess and the sealing flange, wherein first gap, second gap and third space are blind cavity configuration.
Piston ring of the present invention, wherein the thickness of sealing flange accounts for 1/2nd of piston ring thickness.
Piston ring of the present invention; Improved the effect of its sealing gas in cylinder of internal combustion engine; Reduce fuel consumption, improve the output power of motor, piston ring can Yin Gaowen expand and stuck yet simultaneously; And can compensate the increase of the piston ring gap that cylinder wall that long-term use motor causes and piston ring scuffing increase cause through automatic extension, to keep the long-term stability of engine fuel consumption and power.
Description of drawings
Fig. 1 is the schematic representation of piston ring of the present invention.
Fig. 2 is the plan view of the working state of piston ring of the present invention in being installed on piston ring the time.
Fig. 3 is the vertical view cutaway drawing of piston ring of the present invention behind the cylinder of packing into.
Embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed explanation.
Fig. 1 is the schematic representation of piston ring of the present invention; As shown in Figure 1; Piston ring of the present invention comprises cock body 1 and gap 2, and the both sides in gap 2 are respectively the first end A and the second end B of cock body 1, have a seal recess 3 in the outer upper end of first end A; Be provided with in the outer upper end of the second outer end B one with said seal recess 3 corresponding sealing flanges 4, the thickness of sealing flange 4 accounts for 1/2nd of said piston ring thickness.When piston ring was installed in the cylinder 12 in the piston groove 11 on piston 10 outer walls, shown in Fig. 2 and 3, seal recess 3 mate with sealing flange 4 each other, to seal the gas in the cylinder.Because seal recess 3 and sealing flange 4 be axially, radially, and circumferencial direction all has sealing surface, so the effect of sealing gas is better with respect to piston ring of the prior art.
Be provided with the push stopping part 5 that an arc stretches out seal recess 3 front ends in the inner of first end A; Have one in the inner of the second outer end B and end recess 6 with push stopping part 5 corresponding cards; When piston ring was installed in the piston groove on the piston outer wall, push stopping part 5 was ended recess 6 with card and is mated each other.And when piston ring is in the working state that is installed in the piston ring; As shown in Figure 2; Push stopping part 5 and card only leave first gap 9 between the recess 6; Seal recess 3 leaves second gap 8 below sealing flange 4, leave gap the 37 between seal recess 3 and the sealing flange 4, and is stuck because of expanded by heating to prevent piston ring.Wherein said first gap 9, second gap 8 and third space 7 are blind cavity configuration.
Piston ring of the present invention; Improved the effect of its sealing gas in cylinder of internal combustion engine; Reduced fuel consumption, improved the output power of motor, piston ring can Yin Gaowen expand and stuck yet simultaneously; And can compensate the increase of the piston ring gap that cylinder wall that long-term use motor causes and piston ring scuffing increase cause through automatic extension, to keep the long-term stability of engine fuel consumption and power.
