Rotary engine

Abstract

A rotary engine consists of: an elliptic cylinder body (1) and a front cylinder cover (2) and a rear cylinder cover (3) fixed to the cylinder body (1). A separating plate (4) is provided at the centre of the cylinder body (1), which divides the elliptic cylinder body (1) into two approximately semicircular cavities (5, 6), and in the radially symmetric centre line of each of the semicircular cavities there is provided a synchronically rotatable gear shaft (7, 8), respectively; the two gear shafts (7, 8) are supported on the front and rear cylinder covers (2, 3) via a bearing, elliptic gear ring pistons (9, 10) internally meshing with the gear shafts (7, 8) are mounted on the two gear shafts (7, 8), respectively; an inlet valve, an exhaust valve, a gas reserve barrel, and a combustion chamber are provided on the separating plate (4), and an oil nozzle and a sparking plug are provided in the chamber. The present engine has a compact structure, few parts, a small volume, a reduced weight, good sealing, a high working efficiency, and easy maintenance, solving problems present in prior art engines, such as unreasonable structural design, complicated structure, and low efficiency, etc. Engines, and also hydrodynamic machinery such as liquid pumps, hydraulic motors, and air compressors, etc., can be obtained by changing the inlet and exhaust structures.

Description

technical field [0001] The invention relates to an engine, in particular to a rotary engine. Background technique [0002] Most of the traditional engines are reciprocating engines. Because of their inherent structures such as connecting rods, crankshafts, and valves, they have disadvantages such as complex structures and low thermal efficiency. At present, many rotary engine designs try to change this situation, such as the representative Wang Ke Rotary Piston Engine. But the structure design of these existing rotary engines is not very reasonable, can still find the shadow of reciprocating motion or swing in the design, and the fuel consumption rate that also has is higher than reciprocating engine, has not only wasted fuel, but also pollutes the environment. [0003] These will lead to disadvantages such as complex structure, low efficiency or difficult processing. Contents of the invention [0004] The task of the present invention is to provide a new rotary engine w...

Problems solved by technology

[0002] Most of the traditional engines are reciprocating engines. Because of their inherent structures such as connecting rods, crankshafts, and valves, they have disadvantages such as complex structures and low thermal efficiency. At present, many rotary engine designs try to change this situation, such as the representative Wang Ke rotary piston engine

However, the structural design of these existing rotary engines is not very reasonable, and the shadow of reciprocating motion or swing can still be found in the design, and the fuel consumption rate is higher than that of reciprocating engines, which not only wastes fuel, but also pollutes the environment

[0003] And these will lead to disadvantages such as complex structure, low efficiency or difficult processing
