Abstract
A piston ring without end gap comprises a ring body, an upper step surface and a lower step surface. The upper step surface is arranged on the right top of the ring body opening end, and is left a defined gap with the left end surface of the ring body opening end, the lower step surface is arranged on the left bottom of the ring body opening end, and is left a defined gap with the right end surface of the ring body opening end. The bottom end surface of the upper step surface is closely connected with the top end surface contacting part of the lower step surface. So the gas pressed into the gap between the upper step surface and the opening end of the ring body can not enter a crankcase due to the blocking of the lower step surface, so the strict airproof is ensured to prevent leaking gas. The utility model improves the effective power of the gas cylinder, prolongs the service life of the mechanical components, and the production technics is simple, the using is convenient.
Description
Technical field
The utility model relates to a kind of no end gap piston ring.
Background technique
Traditional piston ring all leaves certain fit up gap in its port, and some meeting of pressurized air enter in the crankcase from this fit up gap in work, will reduce compression ratio like this, thereby reduce the useful horsepower of cylinder; Also can cause the mechanical part premature aging simultaneously, reduce its working life.
Summary of the invention
The utility model is all being avoided the above-mentioned deficiency of background technique, provide a kind of can strict seal, prevent the no end gap piston ring that leaks gas.
The utility model is realized by following approach: this nothing end gap piston ring is made up of ring body, appear on the stage terrace and leave from office terrace.The terrace of appearing on the stage is positioned at ring body opening end upper right quarter, and with ring body opening end left side certain clearance is arranged, and the leave from office terrace is positioned at ring body opening end lower left quarter, with ring body opening end right side certain interval is arranged.The terrace lower end surface of appearing on the stage closely is connected with leave from office terrace upper-end surface contact segment.
Be pressed into the gas in appear on the stage terrace and the ring body opening end gap like this,, thereby can guarantee strict seal, prevent gas leakage because of stopping of the terrace of being left office can not enter in the crankcase.
The utlity model has following advantage: can guarantee strict seal, prevent gas leakage, thereby improve the useful horsepower of cylinder, prolong the working life of mechanical part; Production technology is simple, easy to use simultaneously.

Embodiment
As depicted in figs. 1 and 2, the utility model is made up of ring body (1), the terrace of appearing on the stage (2) and leave from office terrace (3).The terrace (2) of appearing on the stage is positioned at ring body (1) opening end upper right quarter, and with ring body (1) opening end left side certain clearance is arranged, and leave from office terrace (3) is positioned at ring body (1) opening end lower left quarter, with ring body (1) opening end right side certain interval is arranged.Terrace (2) lower end surface of appearing on the stage closely is connected with leave from office terrace (3) upper-end surface contact segment.Be pressed into the gas in terrace of appearing on the stage (2) and ring body (1) the opening end gap like this,, thereby can guarantee strict seal, prevent gas leakage because of stopping of the terrace of being left office (3) can not enter in the crankcase.This device has improved the useful horsepower of cylinder, has prolonged the working life of mechanical part; Production technology is simple, easy to use simultaneously.
Claims (2)
1, no end gap piston ring, form by ring body, appear on the stage terrace and leave from office terrace, it is characterized in that: the terrace of appearing on the stage is positioned at ring body opening end upper right quarter, and certain clearance is arranged with ring body opening end left side, the leave from office terrace is positioned at ring body opening end lower left quarter, with ring body opening end right side certain interval is arranged.
2, no end gap piston ring according to claim 1 is characterized in that: the terrace lower end surface of appearing on the stage closely is connected with leave from office terrace upper-end surface contact segment.
