摘要： The present invention relates to a piston assembly with self-adjusting and self-lubricating device. This piston assembly has two piston rings, i.e. one is a combination compression ring, the other is a combination oil control ring. The combination compression ring is composed of a main ring element and an auxiliary ring element. The two ring elements engage with each other on their flat sides, and there is a notch for accommodating lubrication oil provided in the engaging portion. Similarly, the combination oil control ring is composed of a secondary compression ring and a main oil control ring. The construction of the combination oil control ring is substantially as same as that of the combination compression ring. Because the piston assembly has only two rings, its weights, friction forces and inertial forces can thus be reduced, and its sealability, output power can be increased, therefore, the fuel consumption, noise and emission of an engine can be reduced.

摘要： This invention relates to piston compression ring assemblies, each of which consists of a main ring element and an auxiliary ring element. The assemblies can by themselves adjust the radial gaps between the assemblies and the liner, and the gaps between the assemblies and the wall of the ring groove in the piston. The two ring elements engage with each other on their flat sides, and there is a notch for accommodating lubrication oil provided in the engaging portion. The radial cuts in each ring element stagger each other by an angle of 180 DEG . The two ring elements are good sealing and lubricating, respectively, therefore they can reduce the leakage of gas and the compensation of oil, and have a long period of use. They can thus improve the efficiency and the power of internal combustion engine, and reduce the emission and the noise of the internal combustion engine.
摘要翻译：本发明涉及活塞压缩环组件，每个活塞压缩环组件由主环形元件和辅助环形元件组成。组件本身可以调节组件和衬套之间的径向间隙，以及组件之间的间隙和活塞中的环槽的壁。两个环形元件在其平坦侧面彼此接合，并且存在用于容纳设置在接合部分中的润滑油的凹口。每个环形元件的径向切口彼此交错180°。两个环形元件分别具有良好的密封和润滑性，因此可以减少气体的泄漏和油的补偿，并且使用时间长。因此，能够提高内燃机的效率和功率，并且能够降低内燃机的排放和噪音。
