Cylinder body and pump/motor/air compressor/internal combustion engine using same

Abstract

The invention discloses a cylinder body and a pump / motor / air compressor / internal combustion engine using the same. The cylinder body comprises a cylinder body hole, and the section profile curve of the cylinder body hole is an isometric curve. The isometric curve is a non-circular curve and is provided with an abstract rotation center, and any two straight lines which pass through the rotation center and have end points falling on the isometric curve are equal in length. The isometric curve is a closed curve formed by end-to-end-connection of two curves which are generated in the manner that two end points of a straight line section rotate around a fixed point for half a circle and reciprocating once in the length direction of a straight line at the same time. The pump / motor / air compressor / internal combustion engine comprises the cylinder body, and also comprises a main shaft and a sliding block rotor. The main shaft coincides with the rotation center of the isometric curve and is movably connected with the sliding block rotor. The sliding block rotor is a sliding block of the main shaft and is also a rotor of the cylinder body. The sliding block rotor divides the cylinder body hole into two cavities, and the volumes of the two cavities are circularly compressed and expanded along with movement of the sliding block rotor.

Description

technical field [0001] The invention relates to the field of pumps / motors / air compressors / internal combustion engines, in particular to a cylinder and a pump / motor / air compressor / internal combustion engine using the cylinder. Background technique [0002] Among positive displacement pumps / motors / air compressors, vane pumps / motors / air compressors are widely used due to their compact structure, large displacement per unit volume, stable operation, uniform output flow, low noise, and long life. However, vane pumps / motors / air compressors also have disadvantages such as high manufacturing costs and sensitivity to working fluid pollution. [0003] Gasoline and diesel engines in internal combustion engines achieve the purpose of combustion and work by changing the volume of the combustion chamber in cycles, and their working principles are essentially the same as those of pumps / motors / air compressors. Among them, the working principles of the triangular rotor engine and the vane p...

AI Technical Summary

Problems solved by technology

The triangular rotor engine has the advantages of compact structure and high work efficiency, but its main disadvantage is that the compression ratio is low. At the same time, during the operation of the sealing plate, the contact direction with the cylinder bore wall will change greatly, which will affect the air tightness.

[0004] Most importantly, there is currently a lack of a universal simple mechanism that can be applied to pumps, motors, air compressors and internal combustion engines at the same time
