Abstract
The utility model discloses a new dual-bayonet piston ring for internal combustion engines. An overlapping bayonet is designed on a piston ring body, a groove 1 is arranged on one end of the bayonet, a projection 2 whose shape and volume are same to those of the groove is arranged on the place relative to the groove of the other end, the piston ring is under the condition of working, the projection is clamped into the groove, the piston ring is in a circular closed state, and the phenomena of air leakage on the back, tempering and burning oil can not be generated. The piston ring needs to be replaced when the piston ring and the piston are severely worn and cylinder scoring is generated, while the piston also needs to be replaced. So the service life of the piston ring is relatively long, and the utility model has the advantages of simple fabrication and low cost.
Description
The utility model relates to a kind of internal-combustion engine piston ring.
The piston ring that current internal-combustion engine is used has two kinds: a kind of is compression ring; Another kind is an oil ring.Its common trait is that an opening is arranged on the ring body, and there is a gap at the under shed two ends in working order, when piston ring and the increasing of cylinder wear after-opening gap, produces tempering, and lubricant oil is burnt in back gas leakage.Need more renew ring when above-mentioned situation is serious.For prolonging the working life of piston ring, prior art is at the outside of piston ring plating layer of metal chromium, increases the wear resistance of piston ring, but can not solve the tempering that produces in the use, and the lubricant oil phenomenon is burnt in back gas leakage.
The objective of the invention is at the problems referred to above, designed a kind of novel piston ring, do not have tempering during use, the lubricant oil phenomenon is burnt in back gas leakage, and has increased the working life of piston ring greatly.
The present invention is achieved in that the open design of piston ring is become a kind of overlapping bayonet socket that promptly the end outside has a groove, the position of the other end respective slot to be provided with a projection identical with the volume shape of groove.The working state lower protruding block snaps in the groove.
Advantage of the present invention does not have tempering when being work, the lubricant oil phenomenon is burnt in back gas leakage, and piston ring improves more than the twice working life, and processing is simple, and cost is lower than other novel piston ring.

Fig. 2 is the plan view of dual-mouth piston ring bayonet socket
Fig. 3 is the plan view of dual-mouth piston ring bayonet socket
Fig. 1 is a kind of embodiment of the utility model ring, the open design of piston ring is become bayonet socket, one end is into like the arc groove 1 of square, its warp-wise width is the 1/2--3/4 of piston ring warp-wise width, the bayonet socket axial depth is the 1/3-3/4 of piston ring axial thickness, length is 1/2 to 3 times of piston ring axial thickness, the other end is in the position of respective slot 1, be provided with a projection 2 identical with the shape volume of groove 1, piston ring is in working order the time, the groove inner carrier ring upper protruding block 2 that is contained in piston snaps in the groove 1, the interface of its inner rim is in pistion recess, in the groove 1 of outer rim interface survival plug ring, so piston ring is the annulus closed state, can not produce tempering during plug ring work, back gas leakage, burn the lubricant oil phenomenon.Have only the piston ring scuffing of working as serious, just need more renew plug ring when producing pull-cylinder phenomena, when this moment, piston was also to replacing.Therefore, the life-span of piston ring can increase more than the twice.
The groove of piston ring bayonet socket and projection shape can be square body or trigone or trapezoid body or polygonal body or quadrant.
Claims (3)
1, a kind of internal-combustion engine dual-mouth piston ring, it is characterized in that on the piston ring body, having one can be overlapping bayonet socket, there is a groove 1 in the end outside of bayonet socket, the other end has a projection 2 identical with shape, the volume of groove 1 with groove 1 corresponding position.
2, according to claim 1 described piston ring, it is characterized in that the groove 1 of bayonet socket, the warp-wise width of projection 2 are the 1/2-3/4 of piston ring body warp-wise width, axial thickness be the piston ring axon to the thick 1/3-3/4 that rubs, length is the piston ring axon to thick 1/2 to 3 times.
3, according to claim 1 and 2 described piston rings, the shape that it is characterized in that the groove 1 at piston ring bayonet socket two ends and projection 2 can be square, triangle, trapezoid body, polygonal body, quadrant.
