Problems solved by technology

During the operation of this kind of seal ring, the seal is still good at the beginning stage. After a considerable period of operation, the wear between the piston seal ring and the cylinder will cause the flat opening of the piston seal ring to increase continuously. The structure that blocks the airflow, during operation, the airflow will inevitably flow from the side with high pressure to the side with low pressure through the opening, and the oil will flow upwards from this. When it encounters high temperature, the phenomenon of engine oil burning, blue smoke and carbon deposits will occur. , resulting in a reduction in the power of the engine, an increase in energy consumption, and a reduction in the service life of the engine
[0003] Before the present invention is accomplished, the transportation, loading, hoisting machinery or air compressor of the piston engine identical to the improved cylinder of the present invention have not been seen to be housed in people's daily work, and have not been seen to be equipped with the same as the present invention. The transportation, loading, hoisting machinery or air compressor of the piston engine of the improved cylinder with the same structure of the invention are sold on the market, and there is no record of the improved cylinder identical with the present invention in the literature

Abstract

An improved cylinder features that two parallel piston rings are in a slot on piston, the joint of piston ring is butt connected in step mode, the joints of two piston rings are staggered. It is possible that two piston rings are sleeved together. Its advantages are high durability and sealing performance, and elongated service life of engine.

Description

Technical field [0001] The invention relates to a piston engine, in particular to the improvement of the cylinder structure of the piston engine. Background technique [0002] The diameter of the piston in the cylinder of the piston engine is consistent with the inner diameter of the cylinder barrel, and there is a sliding connection between them. Under the action of gas pressure, the piston slides reciprocally along the cylinder barrel. On the piston, a piston ring groove is provided, and a piston ring is embedded in the piston ring groove, and an oil storage ring is also arranged on the piston. In the cylinder of the engine currently used, the piston sealing ring generally adopts a flat opening structure. During the operation of this kind of seal ring, the seal is still good at the beginning stage. After a considerable period of operation, the wear between the piston seal ring and the cylinder will cause the flat opening of the piston seal ring to increase continuously. ...
