Abstract
The utility model discloses an improved sealed piston ring, characterized in that both ends of a lower ring opening (2) are respectively provided with a plug (4) and a slot (9) on the top, the upper end of the plug (4) is provided with a plug meshed oblique plane (5) not communicated with the innercircle end face of the ring; the upper end of the slot (9) is provided with a slot meshed oblique plane (11) not communicated with the innercircle end face of the ring; the meshed length of the intersection of the plug and the slot is 1 to 6mm; when the ring provided by the utility model is not arranged in a slot ring and a cylinder, the end faces of the plug meshed oblique plane (5) and the slot meshed oblique plane (11) have crossed tiny flexible pressure so as to make a better contact between the two meshed planes. The utility model can reduce the leakage of compressed gas and combusted gas in the internal-combustion engine cylinder and extend the service life of the ring.
Description
Affiliated technical field
The utility model belongs to the improvement of internal-combustion engine piston ring, the particularly improved piston cup of sealing.
Background technique
At present, known internal-combustion engine piston ring is in collar extension two tip portion plug and slot to be set respectively in order to reduce the leakage loss of collar extension gap to pressurized gas in the cylinder and combustion gas, is to utilize the interleave Surface of action of plug and slot to seal.Its deficiency is that plug and slot Surface of action are the flat square Surface of action, the Plane of action of slot is difficult for carrying out plain grinding, bring difficulty to processing, so plug and slot interleave Plane of action mutually do not reach a good sealing contact assembling, gang up in interleave Surface of action gap mutually through end opening gap and the plug slot suitable for reading and ring observing this ring use encircling between the middle and later periods, make pressurized gas and the gap leakage loss of combustion gas in the cylinder, make the bad and power deficiency of combustion in IC engine through ganging up.
Summary of the invention:
Use between the middle and later periods in order to overcome known ring, the end opening gap and the plug slot of the suitable for reading and ring of ring are ganged up the gas leakage loss that makes in the cylinder in interleave Surface of action gap mutually, cause the bad and power deficiency of combustion in IC engine.The utility model provides a kind of improved piston ring that seals, and this ring has collar extension good airproof performance simple in structure, can reduce the interior pressurized gas of cylinder of internal-combustion engine and the leakage loss of combustion gas, prolongs the working life of ring.
The purpose of this utility model is to realize like this, a kind of improved piston ring that seals, end opening two tip portion that are included in ring are being provided with plug and slot respectively, plug is made as the engagement of tapered plane phase interleave with the Surface of action of interleave mutually of slot, the phase interleave engagement tapered plane of plug slot is not connected with interior all end faces of this ring, plug and slot interleave length of action mutually are 1-6mm, and collar extension two tip portion were not being established the free squareness of 0.6-2mm up and down when this ring was not contained in annular groove and the cylinder.
Because the utility model ring plug is made as tapered plane with the Surface of action of interleave mutually of slot, its advantage is that the collar extension meshing engagement structure is simple, the engagement tapered plane of plug and slot is easy to carry out plain grinding processing, can make plug with the engagement tapered plane of slot contacting of an excellent sealing be arranged.Because plug and slot interleave mutually mesh tapered plane and are not connected with interior all end faces of this ring, its advantage is that the end opening of the utility model ring is not connected with interior all end faces of ring, the utility model ring used between the middle and later periods, and the gap suitable for reading of the ring not end opening gap of The book of Changes plug and slot engagement tapered plane gap and ring is ganged up.Collar extension two tip portion were being established the free squareness of 0.6-2mm up and down when annular groove and cylinder were interior because this ring is not packed into, plug had micro-elasticity interleave pressure with the engagement of the interleave mutually tapered plane of slot when annular groove and cylinder were interior so the utility model ring is packed into, guaranteed the good contact that the plug and the interleave mutually of slot mesh flat angled end-face, so the utility model ring use the gap of collar extension up and down encircled between the middle and later periods not The book of Changes plug mesh flat angled end-face gap with the interleave mutually of slot and gang up, the pressurized gas in the cylinder of internal-combustion engine and the leakage loss of combustion gas have been reduced, improve combustion in IC engine quality and work power, prolonged the working life of ring.

Embodiment
A kind of improved piston ring that seals, as Fig. 1, shown in Figure 2, the top, two ends that is included in the end opening (2) of ring is being provided with plug (4) and slot (9) respectively, the upper end portion of plug (4) is being provided with the plug engagement tapered plane (5) that is not connected with interior all end faces (10) of ring, the slot engagement tapered plane (11) that is not connected with interior all end faces of ring is being set in the upper end portion of slot (9), plug (4) is 1-6mm with the length of the engagement of interleave mutually of slot (9), the utility model ring cooperates when being installed in annular groove and the cylinder, the installation that is sealed and matched mutually of the engagement tapered plane (5) of plug and the end face of the engagement tapered plane (11) of slot, its good airproof performance, the collar extension gap that this ring uses (1) suitable for reading encircled between the middle and later periods not collar extension gap of the end opening (2) of the engagement end clearance of The book of Changes plug and slot and ring is ganged up, shown in two tip portion squareness of collar extension among figure signal index lines (3): plug engagement tapered plane (5) and the engagement end face of slot engagement tapered plane (11) had mutually the micro-elasticity interleave pressure of interleave can make two to mesh end faces and better contacted when the free squareness that 0.6-2mm was being established at the top, two ends of collar extension when the utility model ring was not packed in annular groove and the cylinder, this ring were packed in annular groove and the cylinder.
