Description

[Technical Field]

[0001] The present invention relates to an engine, and more particularly to a rotary high-pressure gas-powered engine that utilizes the pressure of high-pressure steam or gas as its power source. [Background technology]

[0002]

[0003] Currently, engines play a vital role in automobiles, industrial machinery, and other fields requiring power. Generally, conventional engines, whether internal combustion engines or external combustion engines, achieve a complete power cycle by performing multiple strokes through engagement between components such as cylinders, pistons, crankshafts, and valves.

[0003] With the invention of the steam engine in the 18th century, steam power initiated the First Industrial Revolution and ushered humanity into the age of mechanized production, demonstrating the importance of the steam engine to human civilization. However, because the motion mechanism of traditional steam engines was reciprocating, not only were the engine structure and manufacturing very complicated, but the efficiency of converting work into heat in the engine was also significantly reduced, leading to the obsolescence of traditional steam engines.

[0004] Although traditional steam engines have been abolished, steam power is still used today in industries such as nuclear power, thermal power, and geothermal power generation, where steam turbines are used to convert thermal energy into electrical energy, due to the property that water expands in volume by up to 1,700 times when vaporized.However, because steam turbines use steam openly, they cannot effectively utilize the pressure generated by the large expansion of steam, resulting in very low thermal efficiency.

[0005] Now, as the AI ​​era arrives, a large amount of power is required, and the most important issue is how to provide a steam power generation system that is advanced, simple in structure, and has significantly improved thermal efficiency. Summary of the Invention [Problem to be solved by the invention]

[0006] The primary object of the present invention is to provide a rotary high-pressure gas-powered engine that is powered by the enormous volume change, for example, due to the vaporization of liquid water, and that provides an extremely high performance, highly thermally efficient power source for industry. [Means for solving the problem]

[0009] Hereinafter, possible embodiments of the present invention will be explained by means of examples, which are not intended to limit the scope of protection of the present invention.

[0010] Referring to Figures 1 to 11, one embodiment of the present invention is shown, in which the rotary high-pressure gas-powered engine of the present invention includes a stator mechanism 10, a rotor 20, a spindle 30, a plurality of pistons 40, and a plurality of air covers 50.

[0011] The stator mechanism 10 includes two stators 11A, 11B and two stator oil seals 17. Each of the two stators 11A, 11B includes one guide annular groove 111 and two stator slots 16 extending annularly inside and outside the guide annular groove 111. The guide annular grooves 111 of the two stators 11A, 11B correspond to each other in the axial direction and form rails 12. The two stator oil seals 17 are fitted between the stator slots 16 of the two stators 11A, 11B. Bearings 18 are fitted in the centers of the two stators 11A, 11B. The rotor 20 is rotatably mounted between the two stators 11A, 11B and includes a plurality of cylinders 21 and a plurality of ventilation holes 22. A plurality of slots 212 are formed in a cylinder wall 211 of each cylinder 21, and the ventilation holes 22 open on the outer circumferential surface of the rotor 20 and communicate with the interiors of the cylinders 21, respectively. The spindle 30 is provided with a plurality of axial ventilation slots 31 corresponding to the cylinders 21. The spindle 30 is inserted through the stator mechanism 10 and the rotor 20 and moves synchronously with the rotor 20. Preferably, the rotor 20 is provided with a rotor slot 231, and the spindle 30 is provided with a shaft protrusion 32 protruding from the spindle. The shaft protrusion 32 is inserted into the rotor slot 231 to rotate the rotor 20 synchronously with the spindle 30. The plurality of pistons 40 are provided with piston oil seals 44 around their respective upper and lower ends, and the plurality of pistons 40 are housed in the plurality of cylinders 21, respectively, and are provided with piston shaft rods 41 that protrude axially from the plurality of slots 212 and move along the rail 12. Each of the pistons 40 and each of the piston oil seals 44 moves in an engine oil passage system that is formed by the spaces between the cylinder walls 211 of each of the cylinders 21, the space between the two stator oil seals 17 of the stator mechanism 10, and the plurality of slots 212 communicating with each other.The plurality of air covers 50 are mounted on the stator mechanism 10 so as to be radially movable and elastically recoverable, and cover the outer peripheral surface of the rotor 20. A gas injection space S is formed between each air cover 50 and the outer peripheral surface of the rotor 20, and each air cover 50 includes a gas passage 51 communicating with the gas injection space S for transporting high-pressure gas. When the gas injection space S communicates with the plurality of vent holes 22, the high-pressure gas is introduced into the gas injection space S through the gas passage 51 of each air cover 50, passes through the plurality of vent holes 22, enters the plurality of cylinders 21, and pushes the plurality of pistons 40 to move radially inward, causing the rotor 20 to rotate relative to the stator mechanism 10. When the gas injection space S is not connected to the plurality of ventilation holes 22, the piston shaft rods 41 of the plurality of pistons 40 move along the rail 12, moving the plurality of pistons 40 radially outward and discharging the high-pressure gas in the plurality of cylinders 21 through the plurality of ventilation holes 22.

[0012] In this embodiment, when liquid water is heated to 100°C and becomes steam, its volume expands approximately 1,700 times. Utilizing this characteristic as a power source results in a highly efficient engine. Each air cover 50 is elastically and reversibly attached to the outer surface of the rotor 20, minimizing steam release. Furthermore, the steam pressure within each air cover 50 pushes the air cover 50 outward, significantly reducing frictional resistance between the air cover 50 and the rotor 20 during operation. This significantly reduces frictional energy loss between mechanical components. This allows the rotary high-pressure gas-powered engine to provide a highly efficient and thermally efficient power source for industry.

[0013] The stator mechanism 10 further includes a plurality of bolts 13 and a plurality of bolt sleeves 14. The two stators 11A, 11B each include a plurality of through holes 112. The plurality of bolt sleeves 14 abut between the two stators 11A, 11B. The plurality of bolts 13 pass through the plurality of through holes 112 and the plurality of bolt sleeves 14 of the two stators 11A, 11B, thereby maintaining a constant distance between the two stators 11. When the plurality of bolts 13 pass through the plurality of through holes 112 of the two stators 11A, 11B, the guide annular grooves 111 of the two stators 11 correspond precisely to each other to form rails, which serve to accurately restrict the plurality of air covers 50.

[0014] The rotor 20 includes a rotor body 23 and an annular member 24 circumferentially disposed around the rotor body 23. The rotor body 23 includes the plurality of cylinders 21, and the annular member 24 includes the plurality of vent holes 22, forming a cylinder head. This engagement configuration facilitates processing, manufacturing, and assembly. An annular slot 213 is provided at the outer edge of the top of the cylinder 21. A seal ring 214 is accommodated in the annular slot 213 between the rotor body 23 and the annular member 24. The seal ring 214 seals the gap between the rotor body 23 and the annular member 24, preventing gas from leaking from the gap during the power stroke of the cylinder 21. Preferably, the annular member 24 includes a plurality of recesses 241 spaced apart in the circumferential direction, allowing oil to be supplied from the oil supply holes 54 of the air cover to the recesses 241, and the recesses 241 have an oil storage function to ensure sufficient lubrication between the rotor 20 and the air cover oil seals 52 on both sides of the bottom of the air cover 50. For example, on both sides of the annular member 24, recesses 241 (e.g., small circular holes) are provided every 3 mm at the points of contact with the air covers 50, and each recess 241 is 1 mm deep, but the shape, spacing, depth, etc. of the recesses 241 may be varied to suit design needs.

[0015] The stator 11B is provided with an oil supply hole 114, which is connected to an oil supply pipe 116 that opens upward. Since the oil supply pipe 116 opens upward, lubricating oil enters the engine by gravity. The oil supply hole 114 is provided between the two stator oil seals 17 and is used to inject lubricating oil. The lubricating oil enters the cylinder 21 through the slot 212 and then enters between the stator 11A and the two stator oil seals 17. The stator 11A is provided with an oil drain hole 115, which is connected to an oil drain pipe 117 that opens downward. The lubricating oil finally flows to the rotary high-pressure gas-powered engine 1 through the oil drain hole 115 of the stator 11A, which is connected to the oil drain pipe 117. The engine oil passage system is sealed to ensure sufficient lubricating oil is available to lubricate the moving parts of the rotary high-pressure gas-powered engine 1 during engine operation.

[0016] In this embodiment, the rotary high-pressure gas-powered engine 1 further includes a plurality of air cover shaft rods 60 and a plurality of tension springs 70, and the two stators 11 each include a plurality of stator holes 113, the plurality of air cover shaft rods 60 are inserted into the plurality of stator holes 113 respectively so as to be radially movable, and the plurality of tension springs 70 are respectively connected between the stator mechanism 10 and the plurality of air cover shaft rods 60. More specifically, both ends of each tension spring 70 are hooked onto the air cover shaft rod 60 and the positioning hook member 15 of the stator mechanism 10, respectively, so that when the high-pressure gas pressure drops, each air cover 50 maintains a tendency to move close to the outer circumferential surface of the rotor 20 to avoid insufficient air pressure.

[0017] In this embodiment, each of the stator holes 113 extends long in the radial direction of the stator mechanism 10. An air cover oil seal 52 is further disposed around the end face of the annular recess of each of the air covers 50, and the air cover oil seal 52 contacts the outer circumferential surface of the rotor annular member 24. A portion of the air cover oil seal 52 is firmly fixed in the air cover slot 53 of the air cover 50 with an adhesive material (e.g., a strong adhesive), and the air cover 50 is pressed outward by the high-pressure steam inside the air cover 50, but each of the air cover shaft rods 60 is limited to a slightly long space in the stator hole 113. Since the diameter of the stator hole 113 is larger than the outer diameter of the air cover shaft rod 60, the high-pressure steam cannot completely escape from the constraint of each air cover 50. Therefore, when friction occurs between the air cover 50 and the rotor during operation of the rotary high-pressure gas-powered engine 1, an air cushion or air film is formed between the air cover 50 and the annular member 24 by increasing the steam pressure, so that the friction resistance is extremely small.

[0018] Preferably, each air cover 50 includes at least one oil feed hole 54 that opens to the outer circumferential surface of the rotor annular member 24, and each piston 40 includes an annular recess 42 for storing oil. Specifically, each air cover 50 includes multiple oil feed holes 54, which are located outside the air cover oil seal 52, and each oil feed hole 54 is connected to an oil source via an oil pipe 56 through an oil feed nozzle 55. When each piston 40 moves within the cylinder 21, oil is present in the annular recess 42 of each piston 40, and the large amount of oil allows for effective heat dissipation in addition to sufficient lubrication. Furthermore, the bottom of each piston 40 further includes a cavity 43, thereby reducing weight.

[0019] When the recess 241 of the annular member 24 passes through the opening of the oil feed hole 54, oil enters the recess 241 of the annular member 24, so that the air cover oil seal 52 remains lubricated during operation and friction resistance and friction wear are reduced. The small size of the recess 241 and the wide compressed air cover oil seal 52 cover the recess 241, preventing oil leakage and maintaining the lubrication effect for a long period of time.

[0020] In the preferred embodiment of the present invention, the rail 12 has four equal strokes within 360 degrees, so that the rotating spindle 30 can simultaneously receive operating forces from four power strokes, but the rail 12 may also have two or three equal strokes within 360 degrees (see Figures 12 and 13) or any other number of strokes.

[0021] The operation of the rotary high-pressure gas-powered engine 1 will now be described. When the air cover shaft rods 60 are located at power stroke starting point C, corresponding to the rail 12, radially upstream of the rotor 20, high-pressure gas begins to be transported to the air cover 50 at forward point A, which is before power stroke starting point C. At this time, the pistons 40 are restricted by the rail 12 and do not move. When the piston shaft rods 41 move along the rail 12 until they reach power stroke starting point C, they begin to slide downward along the rail 12, and each cylinder 21 is pushed by high-pressure gas. Therefore, the stroke from forward point A to power stroke starting point C is not considered a power stroke; it merely causes each cylinder 21 to be pressurized early. When the multiple vents 22 move to exhaust point B, the high-pressure gas in each cylinder 21 is exhausted to the outside through the multiple vents 22. In other words, Each cylinder 21 begins to receive pressure when the vent 22 of the rotor 20 moves to correspond to the advance point A within the stroke range. The power stroke begins when the vent 22 of the rotor 20 moves to correspond to the power stroke start point C. The exhaust stroke begins when the vent 22 of the rotor 20 moves to correspond to the exhaust point B.

[0022] Furthermore, at the stage when the piston 40 slides downward along the rail 12, if the air pressure inside the air cover 50 is sufficient to push the piston 40, the piston shaft rod 41 slides downward along the inner side 121 of the rail of the power stroke of the rail 12, and if the air pressure inside the air cover 50 is insufficient to push the piston 40 to move downward (for example, engine stall), the action of centrifugal force causes the piston shaft rod 41 to move along the outer side 122 of the rail of the power stroke of the rail 12.

[0023] The ventilation slots 31 communicate with each of the cylinders 21, and when the piston 40 moves downward in the radial direction of the engine during operation, air below the piston 40 is discharged through the ventilation slots 31. When the piston 40 moves upward in the radial direction of the engine, outside air enters each of the cylinders 21 through the ventilation slots 31.

[0024] Furthermore, in addition to being used as an industrial power source, the rotary high-pressure gas-powered engine 1 of the present invention can also be used to heat cold water using a solar water heater to produce high-temperature hot water, or to use high-temperature geothermal hot spring water to convert non-corrosive water into high-temperature hot water and supply it to a boiler. In this case, when the boiler is slightly heated and the hot water reaches 100°C, the hot water vaporizes and generates high-pressure steam. This high-pressure steam enters the air cover 50 via a gas transport pipe and operates the rotary high-pressure gas-powered engine 1 of the present invention to generate electricity, thus providing a very inexpensive power source. Furthermore, because this rotary high-pressure gas-powered engine uses high-pressure gas in a sealed space and can almost completely utilize the pressure generated by the large expansion of the high-pressure gas only within the sealed space, this high-pressure gas-powered engine is expected to achieve significantly improved thermal efficiency and is a promising means of solving the energy challenges facing humanity.
