Abstract
The utility model discloses an oil-reserving high pressure piston ring and is characterized in that: the outer wall of a piston ring (1) is provided with an oil-reserving groove (2); the outer wall of the piston ring (1) is a slick curved surface. The lubrication effect of the utility model is substantially improved; a large amount of the lubrication oil inside the oil-reserving groove can form an oil seal, thus strengthening the seal effect of the utility model. The outer wall of the piston ring is a slick curved surface and has small contact area with the inner wall of a cylinder; the friction force is also reduced; the power loss of the engine is substantially reduced, thus saving a lot of energies. Besides, during the repair and maintenance of the vehicle, the wearing degree of the piston ring can be determined by measuring the height from the undermost point to the upmost point of the oil-reserving groove, thus convenient for knowing the using status of the vehicle.
Description
Technical field:
The utility model relates to a kind of gasoline, use for diesel engine piston ring, especially a kind of lubricated sealing effect oil storage type high pressure piston ring preferably that reaches.
Background technique:
At present, existing gasoline, diesel powered are provided by motor, and the main member of motor is piston and cylinder, seals by piston ring between the two.A plurality of piston rings generally are installed on the piston, and piston ring is provided with opening, and staggering mutually during installation prevents to lose heart.Piston ring outer wall in the past is vertical, and is bigger with the area of contact of cylinder inner wall, causes mutual frictional force also bigger, influences the output power of motor; And vertical surface can't store lubricant oil, and lubrication effect is not remarkable, the power of same loss motor.And piston ring is through after using for a long time, and the outer wall wearing and tearing are comparatively serious, and also just increasing with the gap of cylinder inner wall, sealing reduces greatly, and disappointing phenomenon is comparatively serious.
Summary of the invention:
The utility model provides a kind of selflubricating oil storage type high pressure piston ring of good sealing effect at the deficiencies in the prior art.
Technical solution of the present utility model is: a kind of oil storage type high pressure piston ring, and it is characterized in that: the outer wall of piston ring 1 is provided with oil storage tank 2, and the outer wall of piston ring 1 is a smooth surface.
Described oil storage tank 2 is an annular.
Outstanding feature of the present utility model is that the outer wall at piston ring is provided with oil storage tank, then can store a certain amount of lubricant oil in it, and lubrication effect obviously strengthens; And a large amount of lubricant oil can form oil sealing, has strengthened its sealing effect.The outer wall of piston ring is a smooth surface, and less with the area of contact of cylinder inner wall, frictional force also decreases, and has obviously reduced the loss of engine power, has saved a large amount of energy.In addition, in the maintenance process of automobile, can determine the wear of piston-rings degree to the height of peak, be convenient to understand the user mode of automobile by measuring the oil storage tank minimum point.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is user mode figure of the present utility model.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1, 2: a kind of oil storage type high pressure piston ring is characterized in that: the outer wall of piston ring 1 is provided with annular oil storage tank 2, and the outer wall of piston ring 1 is a smooth surface.Piston ring 1 is socketed in the outside of piston 3 during installation.
Claims (2)
1. oil storage type high pressure piston ring, it is characterized in that: the outer wall of piston ring (1) is provided with oil storage tank (2), and the outer wall of piston ring (1) is a smooth surface.
2. oil storage type high pressure piston ring according to claim 1 is characterized in that: described oil storage tank (2) is annular.
