Problems solved by technology

However, so far, the above-mentioned eccentric rotor structure has not been applied to the field of fluid motors and engines
The reason is that the problem of cylinder sealing under high frequency and oil-free working environment has not been solved for a long time, which greatly limits the application of this kind of eccentric rotor structure in scenarios such as engines and fluid motors.

Abstract

Disclosed are a rotation device, and a fluid motor, an engine, a compressor and a pump comprising the rotation device. In the rotation device, inlaying grooves for fixing expansion piston rings (621, 622) are formed in the middle of the external cylindrical surfaces of two star wheel fixed flanges (611, 612), the expansion piston rings (621, 622) are in seal fit with the inner cylindrical surface of a cylinder and have gaps of a predetermined size relative to the bottoms and sidewalls of the inlaying grooves, a tiny amount of fluid leaking from the gaps is driven by the rotary motion of the star wheel fixed flanges (611, 612) to form gas film lubrication or fluid film lubrication, thus noncontact seal for a cylindrical inner cavity is realized, and the rotation device can operate in a high-frequency, oil-free working environment.

Description

technical field [0001] The invention relates to the technical field of fluid machinery, in particular to a rotating device and a fluid motor, engine, compressor and pump using the rotating device. Background technique [0002] A power conversion device is an energy conversion device that converts mechanical energy and fluid pressure energy, including, for example, an engine, a fluid motor, a compressor, and a pump. In the traditional field of engines, there are mainly mechanical structures such as reciprocating piston four-stroke engines, triangular rotor engines, and gas turbines. In the traditional field of fluid motors, there are mainly mechanical structures such as piston type, vane type, and gear type. In the traditional field of compressors and pumps, there are mainly mechanical structures such as plunger type, vane type, gear type, screw type and scroll type. For the traditional power conversion device, since its main moving elements are in the form of sliding frict...
