Spiraster-type rotation device, engine, pneumatic motor, and compressor

Abstract

The invention discloses a spiraster-type rotation device, an engine, a pneumatic motor, and a compressor in an annular piston space with a high expansion ratio. In the present invention, a ratio of a linear diameter in the annular piston space to a diameter of a planetary piston wheel of a roller and an angle between a rotary valve sheet of a central sun gear and the diameter of the annular piston space are reasonably provided to effectively increase the expansion ratio of a working substance and reduce an angle in a critical section of the rotary valve sheet, thereby improving the energy utilization rate of the spiraster-type rotation device.

Description

technical field [0001] The invention relates to the fields of engines, air motors and the like in the machinery industry, and in particular to a high-expansion-ratio annular piston space star-rotation device, an engine, an air motor and a compressor. Background technique [0002] For the engine field, there are mainly reciprocating piston four-stroke engines, triangular rotor engines, gas turbines and so on. In the traditional field of compressors and pumps in air motors, there are mainly mechanical structures such as plunger type, vane type, gear type, screw type, and scroll type. While people are using these mechanical structures. Continuous improvement and innovation. [0003] In the patent application (patent application number: 201010196950.8) submitted by the applicant of the present application on June 10, 2010, a spiral fluid motor or engine, a compressor and a pump are disclosed. The entire content of the above-mentioned patent application documents is incorporat...

Problems solved by technology

However, under the condition of large expansion ratio, especially under the impact of high-temperature and high-pressure fluid, the cylinder body using the above processing method is prone to deformation, which will directly affect the symmetry of the annular piston space, resulting in a decrease in the efficiency of the star-shaped rotating device, seriously If so, it may lead to the complete paralysis of the star rotation device

[0010] In the process of realizing the present invention, the applicant realized that there is the following technical problem in the prior art: when the roller planetary piston wheel rolls in the annular piston space, due to the low expansion ratio of the working substance, the above-mentioned planetary rotation device is wasted High energy, low energy utilization
