Description of the invention: [Technical field to which the invention pertains] The present invention relates to a seal for a rotary valve for an internal combustion engine. 5 ❹ 10 . 15 Φ 20 [Prior Art 3 The commercially available internal combustion engine has been slightly modified in principle since 1892. Although there are many different types of internal combustion engines, they all use similar principles. A conventional four-stroke internal combustion engine includes a cylinder block including at least one cylinder bore in which a piston is reciprocally movable, and a crankcase rotatably supporting a crank connected to the piston by a connecting rod a shaft; and a cylinder head including a valve mechanism, the valve mechanism including an intake valve and an exhaust valve open to the cylinder bore. When the crankshaft rotates, the piston reciprocates within the cylinder bore. The rotation of the crankshaft also causes rotation of a camshaft within the cylinder head, so that one of several mechanisms can be used to switch the intake and exhaust valves in the cylinder head. During the induction or intake stroke, the piston moves along the cylinder bore in the direction away from the mechanism and the intake valve is open. A portion of the vacuum in an internal combustion chamber formed in the cylinder bore between the piston and the valve mechanism extracts the atomized fuel and air mixture into the cylinder bore from a carburetor. During a return stroke, the piston moves along the cylinder bore toward the valve mechanism in which the intake valve is closed' thereby compressing the gas in the compression chamber between the piston and the end of the bore in which the intake and exhaust valves are positioned. When the piston reaches the intake and exhaust valves along the cylinder bore and reaches its reciprocating 5 200928077 action, ignition occurs, igniting the compressed fuel and air mixture. This produces a power stroke that pushes the piston in a direction away from the valve mechanism, thereby rotating the crankshaft. 5 Then, the piston moves toward the valve mechanism, and the exhaust valve opens, forcing 5 hot exhaust gas to be discharged from the a-cylinder and the cylinder head, and discharged to the internal boring machine via an exhaust path. The four-stroke internal combustion engine requires a number of components for operating the valve system within the cylinder head. These components increase the cost of the internal combustion engine. The internal combustion engine also emits a large amount of harmful gases in the form of exhaust gas. © 10 In the past, higher-speed and reliable internal combustion engines have been manufactured because of the availability of suitable materials. However, there is still a desire to manufacture other types of internal combustion engines, and another popular commercial product is a two-stroke internal combustion engine. The two-stroke internal combustion engine differs from the more popular four-stroke internal combustion engine i5 in that it performs the same four steps (intake, compression, supply, exhaust) in only two strokes of the piston. This result is achieved by using the compression and the start of the stroke and the post-supply stroke to perform the functions of exhaust and intake, respectively. This allows each turn of the crank to form a supply © power stroke ' instead of every two turns in a four-stroke internal combustion engine to form a power supply stroke. Therefore, the two-stroke internal combustion engine is equipped with high efficiency, so it is more suitable for portable and lightweight applications. However, it has been proposed to replace the valves and ports of the conventional internal combustion engine with a rotary valve to supply gas to a cylinder of the internal combustion engine and to exhaust the gas from the cylinder. U.S. Patent 4,852,532 discloses a rotary valve for an internal combustion engine having a hollow cylindrical rotor inclined-body-formed baffle, and the two have a grass plate along the hole therein. The right side of the baffle is placed on the right side of the baffle so that it can be placed in a solid state in the cylinder when a window is provided and the window is formed to rotate. The rotor is supported by a roller, and the -π of the rotor is supported by a roller on a surface formed on the surface of the thousand, on the inner surface. A plurality of sealing materials, the head of the gas red head - the hole of the hole is placed in the window, and the (four) pieces are arranged in the longitudinal groove #长条结构3δΑβ6,2Ι. The groove is formed in the cylinder

The longitudinal strips are joined to each end of the surface of one of the circumferential rings in a surface contact manner. Several channels are placed in the head of the limb, and the water is cooled and placed in the rotor to cool the oil. The cooling of the rotor is accomplished by lightly radiating heat to the adjacent surface of the rotor bore which is cooled by the water in the water passage and the flowing oil in the oil passage. British Patent No. 22,343,0 discloses a cooling air rotating chamber comprising an intake pipe in a circular cylindrical rotary valve which communicates with an air inlet opening to the cylinder when the pipe is aligned with the cylinder; An exhaust pipe that communicates with an exhaust gas enthalpy that is circumferentially offset from the intake port that is open to the cylinder when aligned with the cylinder. Two circumferential grooves including a seal ring are positioned on both sides of the intake and exhaust ports to isolate the helium and the external environment. The longitudinal 20 seal rods are provided to isolate the intake and exhaust ports. The rotary valve is cooled by passing air through a hole in the valve. U.S. Patent No. 5,941,206 discloses a rotary valve for an internal combustion engine which includes a cylindrical valve rotor having an intake and exhaust port on a circumferential surface of the rotor. A plurality of sealing elements mounted on the valve rotor separate the circumferential surface of the rotor to define a separate circumferential surface area. One of the zones is configured such that when the rotary valve is received in a valve bore in a cylinder head, the sealing member ffltb is attached to the valve bore surface, and the intake and exhaust ports are periodically sealed. 5 WO 02/27165 discloses a rotary valve engine having an internal combustion engine housing housing a ring-shaped timing ring, a rotatable cylinder having a closed end and an open end, and a piston within the cylinder. The cylinder is mechanically driven by a piston via a transmission assembly, and the assembly includes a link that drives a gear and sequentially engages a helical gear formed on the open end of the cylinder. The rotary valve is forced to cool by rotating the oil of the cylinder. U.S. Patent No. 2004/0144361 discloses a rotary valve internal combustion engine including a crankshaft, a throttle valve, a throttle valve starter, a cylinder head, an internal combustion engine, and at least one rotary valve. The rotary valve has at least two turns that form an open end on a periphery thereof, the cylinder head having an aperture 15 and a rotary valve rotating therein. A window in the aperture communicates with the combustion chamber, the opening being continuously aligned with the window by rotation. A drive mechanism provided with a phase change device drives the rotary valve. The ports include an air inlet and an air outlet, and the phase changing means applies a phase change in response to a change in the operating condition of the internal combustion engine in at least one internal combustion engine cycle. A major problem with the rotary valve engine is the need to find a valve that seals the rotary valve to prevent leakage under pressure. No. 5,526,780 discloses a rotary valve for an internal combustion engine, wherein the valve has a combination of an axial seal member and an inner peripheral seal member, the members being configured as a first seal pressurizing bore, the bore being at 200928077. Extending circumferentially between the sealing member and the two second sealing member pressing holes, wherein the two second sealing member pressing holes are located between and adjacent to the outer peripheral sealing member, and the sealing member shaft The valve is positioned on either side of a window opening in a cylinder head and the valve rotates in the cylinder head. The 5 configuration allows high pressure combustion gases to flow from the first cavity to the two second holes such that upon combustion, the outer peripheral sealing elements seal the second due to the force of the axially outermost side of the groove extending toward the periphery The holes are pressurized and the outer peripheral sealing elements are positioned in the grooves to prevent the gas from moving axially outwardly. The inner peripheral sealing members are axially biased inwardly and are sealed toward the axially innermost side of the circumferentially extending groove 10, and the inner peripheral sealing members are positioned in the grooves and axially The four peripheral sealing elements are loaded with weight to seal against a surface of the bore, and the valve is received in the surface of the bore and preloaded towards it. WO 03/100232 discloses a valve seal 15 piece mechanism for a rotatable valve assembly that provides a seal between a rotary valve member and a fixed valve member as used in the same rotary cylinder valve internal combustion engine. In an embodiment®, the seal mechanism includes a substantially rigid sealing frame that surrounds and seals around the valve bore of one of the cylindrical valve members and also seals a surface of the other cylindrical valve member . In another embodiment, the sealer 20 includes an elastically biasable tubular member having a variable diameter that is erected about a first valve member and a diameter of the tubular member is radially A valve bore of the first valve member is aligned and the tubular member is radially biased outside of the first valve member. The cooling of the valve and seal mechanism is accomplished by drawing a coolant passage through a housing in the valve and rotating the lower portion of the valve member for cooling 9 200928077. WO 2005819018 discloses a seal assembly for use in a slewing valve internal combustion engine having a cylinder, the slewing cylinder including a valve port in communication with a combustion chamber. The gas red can be rotated around a longitudinal axis of a cylindrical bore of a valve housing having a hard air port and an exhaust port adapted to be in the housing When the cylinder is rotated, the pull is continuously aligned with the valve 俾 so that the fluid (4) is still rugged and flows out. - the seal is placed around the valve between the cylinder and a common central surface, and includes a rate 10 15 positioned in a recess in the cylinder, in the seal element, in the valve The fluid pressure is free of turbulence on the seal member to urge the seal member into contact with the common center surface and contact the periphery of the groove from the center of the ridge of the cymbal.

The rows of floating seals pass around a window in the bore of the gas (four) The window 'equal valve 相 communicates with the combustion chamber. The row of floating seals includes an axial seal, and a peripheral seal contained in the elongated hole in the hole of the gas red head, (4) a peripheral seal shaft Aligned between the ends of the axial seals. The valve can be extracted by the oil through the valve. ^ wo 2_/024_ exposes the axial flow _ valve for internal combustion engines, which includes - Hole-cylinder head's - axial flow rotation between the holes Rotating in. The valve has a cylindrical central portion, and an air inlet and an exhaust port, the ends of the turns being openings 20 in the central portion. 200928077. The opening periodically passes through the hole a window is in communication with a combustion chamber. A gap between the central portion and the aperture is a row of floating seal seals, the row of floating seals including at least two axial seals, the seals being separated from The opposite side of the window. The assembly further includes at least one floating axial 5 extended shield seal disposed outside the window and spaced away from the axial seal on the periphery. In some examples, the valve is passed The oil extracted by the valve is cooled. Therefore, it is apparent that in the prior art, a complicated mechanical combination is used as a tight seal of a rotary valve to prevent axial leakage under pressure. ❹ [Summary] SUMMARY OF THE INVENTION It is an object of the present invention to at least reduce the disadvantages of the above-described prior art.

Entering in the gas 1_- before [the heat in the domain. The water is thus guaranteed to turn +7 and exit at the rear end 14. The cooling effect of the community 俨u. The rotor 7 is a single piece that can fit any number of rail cylinders at 4 (4) so that the water is discharged through the other end. Unlike some conventional rotary valves, the intake and exhaust gases must use one of the ends. Transfer, and thus only suitable for single-gas burners without any water cooling. An advantage of the rotary valve of the present invention is that the intake and exhaust valves are shaped as a conventional reference for "quasi-internal combustion engines" to allow gas to pass through and exit the side of the rotor. This means that the intake of the cylinder or cylinders can enter the rotor, pass it to its center, and then move down to the cylinder. After the combustion occurs, the exhaust gas in the rotor is opened to allow the exhaust gas to enter the exhaust gas, and is forced to pass through a center of the rotor, and then outwardly through the side of the rotor, and through the cylinder head to the exhaust tube. This allows water to enter the front of the rotor and has a clear passageway around the sides of the rotor that erects the sides of the 15200928077. The control of the thermal expansion of the rotor is easily achieved by maintaining a sliding gap with the gas red head. Referring to Fig. 4, the venting opening 12 has a curved leading edge opening, as shown in Fig. 6 clearly showing 'the leading edge of the carbon deposited on the head surface 18 of the cylinder head, to ensure maximum compression of the combustion force. The air pressure required in the recess 15 to be circulated below is reduced as much as possible to ensure a seal over the life of the entire cylinder head 2 of the internal combustion engine. Referring now to Figures 1 and 7 to 9, in order to maintain the compression of the intake air in the cylinder head 2, a recess 15 is provided which surrounds the cymbal 8 on the outer surface of one of the upper ends of the gas rainbow, and Connected to the air passage, as shown in Figure 8, to form a turbine valve 26. Air is supplied to the turbine valve 26 under pressure. The air may be unobstructed, supplied by a small compressor driven by the crankshaft 3, or as shown in Fig. 6, the required pressure is generated inside the internal combustion engine by the piston 5. When the piston 5 is raised, a valve, not shown, on the side of the crankcase 19 is automatically opened to the atmosphere to allow air to be drawn into the crankcase. When the piston 5 is lowered to the power stroke of the internal combustion engine, the crankcase valve is closed and the piston compresses the air trapped in the crankcase 19, forcing air through the air tube and a check valve 20 into an air storage chamber 21. In a multi-cylinder internal combustion engine, the crankcase 20 has an unobstructed dividing wall that is cast as part of the crankcase or separately configured to provide individual chambers, and the main bearings of the chambers in the crankshaft There is an oil seal on it. This allows the chambers to work in conjunction with a separate air valve system activated by the downward and upward strokes of the pistons in the respective chambers. This charging of the air storage chamber occurs in each power stroke of the internal combustion engine. 16 200928077 twice 'the air storage chamber 21 is provided with a quantity of compressed air. When the piston 5 of the internal combustion engine is raised under compression for its power stroke, a solenoid valve 22 is triggered by an inductor 23 operated by the rotor 7 in the cylinder head 2 into an operating condition '俾 to allow air to pass through the air tube. System 24 and electronic solenoid valve 22 are directed from 5 ❹ 10 15 ❹ 20 air storage chamber 21 to a turbine valve injector 25 that forces compressed air to enter the circular recess 15 generally tangentially, as shown in FIG. As shown, the crucible circulates around the groove 15 of the thirteen wheel valve 26 at a high speed. The miscellaneous valve 26 is positioned at an upper end 'burning to 6' and is only spaced from the periphery 16 of the rotor 7 by 〇 254 claws. 1/1000 of the UK). An upper portion of the wall of the thirteen wheel valve 26 is provided with a contour that is aligned with an outer periphery of the rotor 7, and has a slope 27. Thus, the concentrated air pressure is on the gap 28 of 〇 254 mm (i/i 〇〇〇 之间) between a surface of the rotor 7 and an upper edge of the turbine valve. The pressure circulating in the gap 28 between the thirst wheel valve and the rotor surface is arranged to be higher than the combustion chamber 6 (10) air pressure A' such that all of the material and the detonating combustion gas are maintained in the combustion chamber 6 during compression and power stroke. This external air pressure is maintained in the full wheel valve 26 during the combustion and exhaust stroke of the internal combustion engine. When the exhaust gas diq in the rotor 7 is moved to a position '俾 on the crucible 8 to allow the exhaust gas to be exhausted', the inductor receives a pulse from the rotor and sends a signal that causes the solenoid valve 22 to close. At the same time, the compressed air flowing around the scroll valve 26 flows out to feed the exhaust gas which is about to enter the atmosphere. A conventional __ will emit a large 4 toxic gas into the atmosphere. This is because the discharge valve becomes overheated due to operation, and thus the gas is excessively heated through 17 200928077. Since the internal combustion engine of the present invention operates in a very cool condition and does not cause such problems, the exhaust gas emitted from the internal combustion engine produces less air pollution than the conventional internal combustion engine. It should be understood that the solenoid valve 22 can be replaced, for example, by a mechanical cam driven 5 valve.
