Abstract
The utility model relates to a plunger with an oil reservoir, which is processed into a ring-shaped oil reservoir on the skirt part of the original plunger; the utility model has the advantages that the device can ensure the performance of engine without being influenced, can store the lubrication between cylinder and plunger very well, and can make the lubrication state of frictional pairs between cylinder and plunger better under the situation of long and high speed working so as to increase the reliability of engine.
Description
Technical field
The utility model relates to a kind of piston, particularly relates to a kind of piston with oil storage tank.
Background technique
At at present CB125, CB150[timing chain formula motor] piston on, its skirt section is smooth cylindrical body, the cylndrical surface is smooth smooth, in actual motion, form friction pair between skirt section and the cylinder block, the lubricated oil film that only forms therebetween by the lubricant oil of crank-connecting rod combination splash, along with piston constantly pumps, lubricant oil between friction pair partly splashes into casing, partly burned, this just makes under the situation of the long-term high load running of motor, the insufficient lubrication between piston and the cylinder block friction pair often occurs and causes accidents such as scuffing of cylinder bore.
Summary of the invention
In order to solve the pull-cylinder phenomena that causes because of insufficient lubrication between above-mentioned piston and the cylinder block friction pair, the utility model provides a kind of piston with oil storage tank.
The utility model is achieved in that a kind of piston with oil storage tank, comprises piston body, is processed with annular oil groove in the skirt section of piston body.
Because the utility model has processed annular oil groove in the skirt section of former piston body, this oil groove can be guaranteed under the situation that does not influence engine performance, can lubricant oil be stored between cylinder block and the piston better, even make motor under situation about running up for a long time, also can make piston and cylinder block friction lubricating good, thereby improve the reliability of motor.
Description of drawings
Fig. 1 is a structural drawing of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1.
Embodiment
Referring to accompanying drawing as can be known, a kind of piston with oil storage tank comprises piston body 1, is processed with annular oil groove 2 in the skirt section of piston body 1.
In this example, described annular oil groove 2 has two.
Claims (2)
1, a kind of piston with oil storage tank comprises piston body (1), it is characterized in that: be processed with annular oil groove (2) in the skirt section of described piston body (1).
2, the piston of band oil storage tank according to claim 1 is characterized in that: described annular oil groove (2) has one at least.
