Abstract

A slide block type rotor engine respectively completes four strokes of air suction, compression, work doing and air exhaust through two groups of different cylinder bodies and two groups of front and rear air chambers formed on two sides of a slide block which rotates along with a main shaft and slides in the main shaft along the inner cambered surface of the cylinder body, and directly outputs power through the main shaft.

Description

Slide block type rotor engine

The invention relates to a slide block type rotary engine.

The internal combustion engine widely used at present is a reciprocating piston engine, also called a diesel engine, and has the defects of complex structure and large volume. For more than half a century, countless people have invented various forms of rotary engines, typically represented by wankel engines, which have not been widely used in practical applications due to their poor exhaust and low speed performance and low thermal conversion efficiency.

The invention mainly aims to provide a sliding block type rotor engine which has the advantages of simple structure, small volume, light weight, energy conservation and environmental protection and is suitable for the modern development requirement.

In the accompanying drawings, one embodiment of the invention is illustrated by way of non-limiting example:

FIG. 1 is a bottom perspective view of a rotary slide engine

FIG. 2 is a sectional view taken along line A-A

FIG. 3 is a sectional view taken along line B-B

In the figure:

1. installing a base; 2. installing bolt holes; 3. the end cover connecting bolt of the suction cylinder and the pressure cylinder; 4. air suction and compression cylinder bodies; 5. a cylinder block coupling bolt; 6. a gas passage; 7. a power and exhaust cylinder; 8. connecting bolts for the end covers of the power cylinder and the exhaust cylinder; 9. a power take-off shaft; 10. a suction pressure chamber; 11. A main shaft; 12. sucking and pressing the cylinder wall of the cylinder; 13. an air suction port; 14. a main shaft sealing strip; 15. a seal spring; 16. a spindle lubricating oil passage; 17. a slide block lubricating oil channel; 18. an inner arc surface of the suction cylinder; 19. a slider sealing strip and a spring; 20. a suction cylinder slider; 21. compressed gas passing through the air holes; 22. a conical single-chamber valve; 23. a check valve spring; 24. a check valve fastening bolt; 25. inner arc surfaces of the power row cylinders; 26. a seal spring; 27. lubricating oil channels of the sliding blocks of the power cylinder and the row cylinder; 28. a power and row cavity; 29. the cylinder walls are arranged; 30. a power row sliding block; 31. A spark plug; 32 an exhaust port; 33. a power row cylinder main shaft sealing strip; 34. a lubricating oil passage of a main shaft of the power row cylinder; 35. a combustion chamber; 36. an air inlet; 37. a valve stem; 38. an air valve inner chamber; 39. a valve spring; 40. a valve spring clip; 41. valve seat

Referring to the attached figure 1, the engine is formed by connecting two groups of cylinders, an air suction cylinder 4, a compression cylinder 4, a power doing cylinder 7 and an exhaust cylinder 7 through an air suction end cover connecting bolt 3, a pressure end cover connecting bolt 5 and a power exhaust end cover connecting bolt 7.

Referring to fig. 2, the suction cylinder slider 20 has two air chambers formed on both sides thereof, one side being a suction air chamber and the other side being a compression air chamber, and when the slider 20 rotates along with the main shaft 11, one side sucks air through the suction port 13 and the other side compresses air; when one end of the slide block rotates to the section of the inner arc surface 18 of the suction pressure cylinder along with the main shaft 11, compressed gas pushes the one-way valve 22 open through the gas passage 21, and the compressed gas is sent to the gas passage 6 of the cylinder body.

Referring to fig. 3, compressed gas is forced through the cylinder gas passage 6 into the cylinder valve chamber 38, and when the end of the cylinder slide 30 rotates with the spindle through the gas inlet 36, a vacuum is created in the gas inlet, the valve opens, and compressed gas enters the combustion chamber 35. When the slide block 30 rotates the spark plug 31, the over-gas stage is completed, the spark plug ignites, the air pressure rises, the air inlet valve closes, the compressed gas in the combustion chamber burns to do work, and the other side of the slide block 30 exhausts.

Referring to fig. 2 and fig. 3, the suction and pressure cylinder slide block 20 and the power and power row cylinder slide block 30 are installed in different chutes of the same main shaft at an angle of 90 degrees, and the slide blocks only synchronously rotate along with the main shaft in the main section of four strokes of suction, pressure, power and power row. And in the gas passing stage, the sliding block rotates along with the main shaft and also slides along the inner arc surface of the cylinder body in the radial direction. Every time the main shaft rotates 180 degrees, the two cylinders respectively complete four strokes of air suction, compression, work doing and air exhaust at the same time, and the process is repeated.

The invention completely cancels complex mechanisms such as cranks, connecting rods, valve cams and the like, and compared with the traditional reciprocating piston engine, the sliding block type rotor engine has the advantages that the volume is greatly reduced by ①, the weight is greatly reduced, ② adopts a sliding block structure, theoretically, waste gas can be completely exhausted, so the combustion quality can be improved, the harmful gas emission is greatly reduced, simultaneously carbon deposit in a combustion chamber can be avoided, the adverse effects such as a burning explosion phenomenon and the like are avoided, ③ the impact, the uneven wear and the like can be reduced and the output of effective power can be greatly improved because the pressure of combustion gas uniformly acts on a main shaft through the sliding block, more particularly, the invention has simple structure, the miniaturization of the engine can be realized, and ideal power can be provided for emerging industries such as unmanned aerial vehicles, field robots and the like.
