Problems solved by technology

[0002] Existing internal combustion engine (the most used is automobile engine) is that the piston ring embedded on the piston is in contact with the cylinder wall. When the piston reciprocates, sliding friction occurs between the piston ring and the cylinder wall, thereby consuming energy, reducing efficiency, and being easy to Wear and tear, so that cylinder scuffing accidents often occur, so frequent maintenance is required, and it is troublesome to replace wearing parts such as piston rings and cylinder liners

Embodiment Construction

[0016] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation to the present invention.

[0017] A method for changing sliding friction between a piston and a cylinder into rolling friction is realized by rolling marbles or rollers on the cylinder wall.

[0018] refer to figure 1 , figure 2 It can be seen that one embodiment of the present invention is composed of a piston body 1 and several rolling elements 2 located around the piston body, and there is a connecting fixture 3 between the piston body and the rolling elements.

[0019] The rolling body 2 is a roller, the connecting fixture includes an upper piston sleeve 3-1 and a lower piston sleeve 3-2, and the roller 2 is located between the upper piston sleeve 3-1 and the lower piston sleeve 3-2 In the groove 3-3, and partially located outside the opening 3-4 between the upper piston sleeve and the lower piston s...

Abstract

The present invention relates to a rolling piston capable of changing the sliding friction between piston and cylinder into rolling friction. It includes piston body, several rolling bodies positioned around the piston body and fixing device connected between piston body and rolling bodies. Besides, said invention also provides its working principle.

Description

technical field [0001] The invention relates to a rolling piston that changes the sliding friction between the piston and the cylinder into rolling friction, which can be used for high-temperature, high-pressure, high-speed reciprocating piston and cylinder structures such as internal combustion engines, and can also be used for low-temperature and low-pressure reciprocating piston and cylinder structures such as compressors. . Background technique [0002] Existing internal combustion engine (the most used is automobile engine) is that the piston ring embedded on the piston is in contact with the cylinder wall. When the piston reciprocates, sliding friction occurs between the piston ring and the cylinder wall, thereby consuming energy, reducing efficiency, and being easy to Wear and tear, so that cylinder scuffing accidents often occur, so frequent maintenance is required, and it is troublesome to replace wearing parts such as piston rings and cylinder liners.
