Abstract

The invention provides a rotating device and a fluid motor, an engine, a compressor and a pump using the same. In the rotating device, a non-contact sealing structure of a cylindrical inner chamber of a cylinder body is achieved through a gas film lubricating design or a liquid film lubricating design between an expansion piston ring and a star wheel sealing flange so that the rotating device can be operated in a high-frequency and 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...
