Abstract
The utility model relates to a piston ring, specifically relates to the piston ring with a cap liner, including a ring body, which is characterized in that the two sides of a notch of the ring body are provided with an arc rabbet, one side of the cap liner is welded with the arc rabbet at one side of the notch, another side of the cap liner is matched with the arc rabbet on another side of the notch. Because the cap liner and the ring body adopt the welding way to connect, so the utility model is difficult to fall off and conveniently installed and used. After arranging the utility model on the piston and matching with a cylinder sleeve, the cap liner axially seals the notch of the ring body, thereby increasing the sealing effect, reducing the exhaustion of the cut through air leakage and motor oil, better improving the complete appliance property of the motor. The piston can be provided with one to three piston rings with the cap liner, which can be used in match with the normal piston or a combined piston ring, has a better sealing effect.
Description
The utility model relates to piston ring, is specifically related to a kind of piston ring with seal plate, and it is applicable to various conventional engines.
Technical background
Traditional piston ring is the monocycle that has straight cut, is contained on the piston with after cylinder body cooperates, though the contact of otch two ends, but still have straight-through gas leakage gap.In order to strengthen sealing to cylinder body, this piston ring in 2-3 road is housed on piston usually, and otch is staggered mutually, form the sealing configuration of " labyrinth " formula.The sealing configuration of this throttle type working principle, though the effect of certain enhanced leaktightness is arranged, but still have the defective of leakage gas.Particularly in use, the close mutually even alignment of each piston ring otch can occur, cause the phenomenon of short circuit gas leakage that the significant sealing affection variation takes place.The straight cut piston ring is used for the piston ring-piston assembly of complex piston engine, is difficult to improve the complete machine performance of motor by the service behaviour of giving full play to each piston ring.
Summary of the invention
The purpose of this utility model provides a kind of piston ring with seal plate, and it can reduce straight-through type gas leakage, reaches the technique effect that strengthens sealing and the oil consumption of control machine oil, improves engine performance.
A kind of piston ring with seal plate described in the utility model comprises ring body, it is characterized in that being provided with arc-shaped slot at the otch two ends of ring body, and an end of seal plate is welded in the arc-shaped slot, the other end of seal plate and arc-shaped slot corresponding matching.The width of seal plate is less than or equal to the degree of depth of arc-shaped slot.
Because seal plate adopts the mode of welding to be connected with ring body, is not easy to come off, and is easy to install.The utility model is contained on the piston with after cylinder sleeve cooperates, and seal plate has strengthened sealing effect from radially the otch of ring body being sealed, and reduces the loss of straight-through type gas leakage and machine oil.Can improve the complete machine performance of motor preferably.
Description of drawings
Fig. 1 (a) is a structural representation of the present utility model, (b) is the plan view of (a).
Embodiment
Referring to Fig. 1 (a), the two ends of existing finished product piston ring are processed arc- shaped slot 2 and 3 on wire cutting machine tool, use laser bonding in the arc-shaped slot 2 of otch one end of ring body 1 at an end of seal plate 4 again, the other end of seal plate 4 and arc-shaped slot 3 corresponding matching get final product.The piston ring of 1 to 3 this band seal plate can be installed on piston, also can be used with common piston or compound piston ring, its sealing effect is better.
Claims (2)
1, a kind of piston ring with seal plate, comprise ring body (1), it is characterized in that being provided with arc-shaped slot (2) and (3) at the otch two ends of ring body (1), an end of seal plate (4) is welded in the arc-shaped slot (2), the other end of seal plate (4) and arc-shaped slot (3) corresponding matching.
2, a kind of piston ring with seal plate according to claim 1 is characterized in that the width of seal plate (4) is less than or equal to the degree of depth of arc-shaped slot (3).
