Title:
ENGINE
Document Type and Number:
WIPO Patent Application WO/2022/183840
Kind Code:
A1
Abstract:
An engine, comprising both oil-driven and pneumatic structures. The two structures are slightly different, but the overall structures and principles are the same, i.e., both relating to a cylinder-piston structure, comprising no crankshaft and connecting rod. The structure is symmetrical and reasonable and can achieve more stable transmission. When the engine is running, with the action of the centrifugal force or the air pressure of an air chamber and under the restriction of a piston limiting track in a casing, a piston mechanism in a cylinder on a rotor core completes the actions required for the four-stroke of an oil-driven engine or the actions required for a cycle consisting of air intake, air exhaust, air re-intake, and air re-exhaust of a pneumatic engine. In addition, under the action of an air valve spring and a valve limiting track in the casing, an air valve of an air valve mechanism also completes the opening and closing required for the four-stroke or pneumatic purpose, such that the engine can operate.
