Description

Technical Field

[0001] This invention relates to a rotary piston machine. More specifically, this invention relates to a rotary piston machine having an endocycloidal profile and a rotary valve for controlling the inflow and outflow of fluid in a variable-volume chamber. Background Technology

[0002] Existing reciprocating internal combustion engines are characterized by a large number of parts, high complexity, and large overall size / dimension. Rotary piston engines typically have fewer parts and a smaller size / dimension. The main disadvantages of existing rotary piston engines are lower fuel efficiency and higher emissions. Furthermore, the port-type fluid exchange system used in existing rotary engines results in significant energy loss in the exhaust stream. Additionally, in internal combustion engine (ICE) configurations, most existing rotary piston machines exhibit temperature and expansion differences (some areas are cold, some areas are hot), which leads to certain operational problems. Summary of the Invention

[0003] This invention discloses a rotary piston machine, comprising: a housing having an internal cycloidal profile. Furthermore, the rotary piston machine also includes a rotor assembly having an approximately cycloidal profile. The apex of the rotor assembly abuts against the cycloidal profile of the housing, and the relative motion between the housing and the rotor assembly generates a variable volume. The variable volume allows the rotary piston machine to operate as a compressor, expander, internal combustion engine, positive displacement pump, or fluid-driven motor.

[0004] In one embodiment, the rotary piston machine operates in a single-rotation mode, wherein the rotor assembly and the housing rotate synchronously in the same direction about their fixed, non-coincident axes with a fixed transmission ratio. The rotation of the rotor assembly and the housing is synchronized with relative transmission ratios via a phase adjustment mechanism. Furthermore, in an embodiment employing a planetary rotation mode, the rotor assembly is mounted on an axis eccentric to the housing axis, revolving around the housing axis while simultaneously rotating on its own axis in the opposite direction to the axis's rotation, and maintaining phase synchronization with the fixed housing.

[0005] The rotor assembly includes a sealing mesh consisting of side seals, a top seal, and corner sealing elements bridging the top and side seals. The sealing mesh forms a three-dimensional continuous sealing path between the rotor assembly and the housing, preventing fluid leakage from the working chamber.

[0006] In planetary rotation mode, the housing is further provided with one or more rotary valves on each side of the fixed housing, with their ports opening into the working chamber. The rotary valves allow fluid to enter / intake / input and exit / exhaust / output from the working chamber. The arrangement of the rotary valves depends on the function of the rotary piston mechanism. The rotary valves are driven by a synchronizing mechanism to allow fluid to enter / intake / input and exit / exhaust / output from the variable-volume working chamber at predetermined time intervals.

[0007] In an embodiment of a four-stroke internal combustion engine (ICE) employing a planetary rotation mode, the cycloidal profile has an even number (n) of sides. Further, the corresponding outer surface of the rotor assembly, approximating the cycloidal profile, has an odd number (n-1) of sides (one less than the number of sides of the housing), the vertices of which abut against the inner cycloidal profile during operation. In the ICE planetary rotation mode embodiment, the housing includes one or more rotary valves disposed on alternating sides of the even-numbered-side cycloidal profile. The alternating sides of the even-numbered-side cycloidal profile without valves contain combustion devices for operation as an internal combustion engine. In one embodiment, the rotary valve arrangement includes a rotary valve controlling the intake and exhaust / output processes.

[0008] In one embodiment, the rotary valve arrangement includes at least two rotary valves adjacent to each other on each side of the cycloidal profile, wherein at least one rotary valve is dedicated to air / fluid inlet / intake / input, and at least one rotary valve is dedicated to air / fluid exhaust / output.

[0009] The present invention discloses a method for generating power using a rotary piston machine in an internal combustion engine embodiment, comprising four-stroke operation—intake, compression, power, and exhaust—which are performed during relative motion of the rotor assembly within the housing, wherein the intake and exhaust processes are handled by a rotary valve system in an appropriate timing manner, and power is generated by a combustion device.

[0010] When operating as a compressor, expander, positive displacement pump, or fluid-driven motor, the rotary piston machine has a rotary valve on each side of the cycloidal profile, and its working process is divided into two cycles—inlet / intake / input and exhaust / output.

[0032] See Figure 1 A cross-sectional view of a rotary piston machine 100 (e.g., a rotary internal combustion engine 102, simply referred to as engine 102) is shown. Although the rotary piston machine 100 is shown and contemplated as a rotary internal combustion engine 102, it is conceivable that the rotary piston machine 100 could be a rotary compressor, a positive displacement pump, an expander, or a fluid-driven motor. As shown, engine 102 includes a housing 104, for example a fixed housing, having an inner surface 106 defining a chamber 108; and a rotor assembly 110 disposed within the chamber 108 and configured to rotate within the chamber 108. The rotating assembly operates in a planetary rotation mode, wherein the rotor assembly 110 revolves about an eccentric axis offset from the axis of the fixed housing 114, while rotating on its own axis in the opposite direction to the output shaft 111.

[0033] Furthermore, the inner surface 106 of the housing 104 is an incycloid profile with an even number of sides (n) 112, while the outer surface 114 of the rotor assembly 110 also includes a profile with an odd number of sides (n-1) 116, the vertices of which abut against the inner incycloid profile during operation. In the illustrated embodiment, the housing 104 includes 6 sides, and the rotor assembly 110 includes 5 sides. The rotor assembly 110 is disposed inside the housing 104 such that multiple variable volume cavities 118 are defined between the multiple sides 116 of the rotor assembly 110 and the housing 104. As shown, each side 116 defines a single variable volume cavity 118 with the housing 104. As the rotor assembly 110 revolves within the housing 104, the volume of each cavity 118 continuously changes, thereby defining the various strokes of the engine 102. Furthermore, the portion of the outer surface 114 associated with each side 116 defines a combustion chamber recess 119 (e.g., Figure 2 As shown in the figure, the air-fuel mixture is ignited at the recess at the start of the combustion stroke.

[0034] To prevent fluid exchange between cavities 118 and gas leakage from cavities 118, such as Figure 2 and Figure 3 As shown, the engine 102 includes a sealing mesh 120 connected to the rotor assembly 110. As illustrated, the sealing mesh 120 includes a plurality of top seals 122 and a plurality of side seals. The plurality of side seals includes a plurality of first side seals 124 extending along a first side edge 126 of the rotor assembly 110, and a plurality of second side seals 130 extending along a second side edge 132 of the rotor assembly 110. The plurality of top seals 122 extend between the plurality of first side seals 124 and the plurality of second side seals 130, and are positioned along a plurality of vertices 134 defined at the intersection of adjacent sides 116 of the rotor assembly 110.

[0035] Furthermore, the sealing mesh 120 includes a plurality of first corner connecting seals 136 connected to the rotor assembly 110 and connecting a plurality of first side seals 124 and a plurality of top seals 122. As shown, a single first corner connecting seal 136 is disposed at the intersection of at least two adjacent sides 116 of the rotor assembly 110 and connects at least two adjacent first side seals 124 and a single top seal 122 disposed therebetween. Similarly, the sealing mesh 120 includes a plurality of second corner connecting seals 138 connected to the rotor assembly 110 and connecting a plurality of second side seals 130 and a plurality of top seals 122. As shown, a single second corner connecting seal 138 is disposed at the intersection of at least two adjacent sides 116 of the rotor assembly 110 and connects at least two adjacent second side seals 130 and a single top seal 122 disposed therebetween. Side seals 124 and 130 restrict / prevent gas leakage through the gap between rotor assembly 110 and housing 104, while top seal 122 prevents / restricts gas leakage between adjacent cavities 118. It is understood that each vertex 134 defines a recess (not shown) to receive a portion of the associated top seal 122, and a portion of the top seal 122 extends outward from the recess (not shown) and contacts the inner surface 106 of housing 104.

[0036] In some embodiments, see Return Figure 1 Engine 102 may be a spark-ignition engine. In this case, in order to promote the combustion of the air-fuel mixture in the chamber 118 at the end of the compression stroke, engine 102 includes a plurality of combustion devices 142, for example, three combustion devices 142, which are mounted on housing 104 and configured to provide a spark at the end of the compression stroke to ignite the air-fuel mixture.

[0037] To facilitate the entry of the air-fuel mixture into the chamber 118 during the intake stroke and the expulsion of exhaust gases from the chamber 118 during the exhaust stroke, the engine 102 includes a plurality of rotary valves 144, for example, three valves 144, which are mounted at a plurality of ports 146 of the housing 104. It is understood that more than one port 146 may be associated with a single rotary valve 144. As shown, the arrangement of the ports 146, rotary valves 144, and combustion devices 142 allows a single combustion device 142 to be mounted on a side 112 of the housing 104, which is disposed between two adjacent sides 112 of the housing 104 having ports 146. As shown, at least one rotary valve 144 is disposed between at least two combustion devices 142, and at least one combustion device 142 is disposed between at least two rotary valves 144. For example, a single rotary valve 144 is disposed between two combustion devices 142, and a single combustion device 142 is disposed between two rotary valves 144.

[0038] Additionally, see Figure 4 The engine 102 includes an actuation mechanism 150 for actuating and operating the opening and closing of a rotary valve 144. In the illustrated embodiment, the actuation mechanism 150 includes a gear assembly 152 connected to an output shaft 111 and configured to rotate the rotary valve 144. The selection, setting, and configuration of the gears in the gear assembly 152 cause the rotary valve 144 to open and close associated ports 146 according to desired timing to allow the intake of an air-fuel mixture and the exhaust of gases. Similarly, a plurality of drive outputs 148 are also included to drive ignition, lubrication, and other systems as needed. Although the actuation mechanism 150 is shown and contemplated as a gear assembly 152, it will be understood that the actuation mechanism 150 may include a sprocket and chain assembly, a timing belt assembly, a pulley assembly, or any combination thereof known in the art.

[0039] Alternatively, engine 102 may be a compression ignition engine, and in this case, engine 102 may include a fuel injector instead of combustion device 142 to inject fuel into the cavity 118 at the end of the compression stroke. Any combustion device, such as a laser, plasma device, pre-combustion chamber system, or any other device known in the art, may be used in the ignition process.

[0040] In addition, see Figure 5 and Figure 6 The rotary piston machine 100 (i.e., engine 102) includes a phase adjustment mechanism 160 to maintain the rotor assembly 110 and housing 104 in a predetermined phase during operation of the engine 102. As shown, the phase adjustment mechanism 160 includes a first gear 162, such as an external gear 162, connected to the rotor assembly 110, and a second gear 164, such as an internal gear 164, operatively engaged with the first gear 162 and connected to the housing 104. In the illustrated embodiment, the phase adjustment mechanism 160 may include a fixing structure 166 to which both the second gear 164 and the housing 104 are attached. It is understood that the phase adjustment mechanism may consist of any other means known in the art.

[0041] Now for reference Figures 7 to 17 Explain the operation of engine 102. As shown in the figure, refer to one of the cavities 118, such as cavity 118a, to explain the operation. When the output shaft 111 rotates clockwise, the rotor assembly 110 rotates counterclockwise inside the housing 104 while simultaneously revolving eccentrically. Figure 7 The diagram shows the position and associated volume of chamber 118a at the end of the exhaust stroke and the beginning of the intake stroke, corresponding to the top dead center position of the piston in a reciprocating internal combustion engine. (See diagram for details.) Figure 7 and Figure 8As shown, when the rotor assembly 110 rotates and revolves relative to the output shaft 111, the air-fuel mixture flows into the cavity 118a due to the suction caused by the increase in the volume of the cavity 118a. When the volume reaches the volume corresponding to the maximum scavenging volume (e.g., ... Figure 9 As shown in the figure, that is, corresponding to the bottom dead center position of the piston of the reciprocating internal combustion engine, the intake stroke ends in chamber 118a.

[0042] As the output shaft 111 rotates further, and consequently the rotor assembly 110 rotates eccentrically on the output shaft 111 while rotating in the opposite direction, the volume of cavity 118a begins to decrease, initiating the compression stroke (e.g. Figure 10 As shown), this compresses the air-fuel mixture present in chamber 118a. As the rotor assembly 110 rotates, the volume inside chamber 118a reaches its minimum value (as shown). Figure 12 As shown), this indicates the completion of the compression stroke. At this time, according to the predetermined timing, the associated combustion device 142 is actuated to ignite the spark chamber 118a (i.e., Figure 2 The air-fuel mixture present in the combustion chamber recess 119 shown.

[0043] Due to the ignition of the air-fuel mixture in cavity 118a, the gas present in cavity 118a expands, generating power and rotating rotor assembly 110 to initiate the power stroke (e.g., Figure 12 (As shown). During the power stroke, the volume of cavity 118a increases and reaches the level shown. Figure 14 As shown in the orientation, at this time, according to the timing determined by the design operating parameters, the associated rotary valve 144 is opened. As the rotor assembly 110 moves further, the volume of cavity 118a begins to decrease, expelling the exhaust gas present in cavity 118a through port 146 of housing 104, as... Figure 15 and Figure 16 As shown. Figure 17 The completion of the exhaust stroke and the start of the new intake stroke in cavity 118a are depicted. In this way, due to the 5:6 combination, three (3) power strokes occur during a single rotation of output shaft 111 in a four (4) stroke operation, as... Figure 18 As shown. The number of four-stroke operations depends on the number of cavities 118 defined by the combination of housing 104 and rotor assembly 110, and the number of power strokes occurring during a single rotation of output shaft 111 is equal to half the number of housing sides.

[0044] See Figure 18An alternative engine 202 is shown. The engine 202 differs from the engine 102 in that, instead of a single rotary valve 144 that allows intake and exhaust between the two combustion devices 142, the engine 202 includes an intake rotary valve 204 that is actuated to allow only air to enter and an exhaust rotary valve 206 that is operated to allow exhaust gases to exit.

[0045] In another exemplary embodiment, in the 7:8 combination, during a single rotation of the output shaft 111, four (4) power strokes occur during the four (4) stroke operation, such as Figure 19 As shown.

[0046] See Figure 20 An alternative engine 302 is shown. Engine 302 differs from engine 102 in that it includes a housing 304 with eight sides, which is a rotatable housing configured to rotate about a central axis; and a rotor 306 with seven sides. Therefore, during operation of engine 302, both housing 304 and rotor 306 rotate in phase. In this case, rotor 306 rotates about its central axis, rather than revolving eccentrically.

[0047] The rotary piston machine 100 with its cycloidal profile is easier to seal, primarily due to the smaller "tilt angle" of the top seal of the sealing mesh. Furthermore, the inclusion of a rotary valve allows for better control of the fluid exchange process, resulting in better control of both intake and exhaust processes (for engine applications). Similarly, the output of engines 102, 202, and 302 is much smoother than that of reciprocating internal combustion engines, as there are three (3) power pulses per revolution of the output shaft for a single 5:6 combination, compared to four (4) power pulses per revolution for a single 7:8 combination.

[0048] Furthermore, while an engine 102 with an introcycloidal profile is shown and envisioned in some embodiments, it is understood that the rotary valve system can be applied to rotary piston machines including an exocycloidal profile, any other suitable subcycloidal, cycloidal, or other profile.

[0049] See Figure 21 A compressor / pump is shown. The housing has rotary valves arranged adjacent to each other. The rotary valves may include an inlet / inlet rotary valve 204 for supplying low-pressure fluid on one side during an inlet / inlet cycle, and a discharge / exhaust / output rotary valve 206 for releasing high-pressure fluid during a compression cycle. The inlet / inlet rotary valve 204 is open during an inlet / inlet cycle, and the adjacent discharge / exhaust / output rotary valve 206 remains closed. Fluid flows into the cavity as the volume of chamber 118a increases. When chamber 118a reaches a volume corresponding to the maximum scavenging volume (e.g., ...), Figure 9 As shown), the intake / intake stroke ends. With further rotation of shaft 111, and consequently, rotation of rotor assembly 110 in the opposite direction while eccentrically revolving on shaft 111, the volume of cavity 118a begins to decrease, initiating the compression stroke within cavity 118a. As rotor assembly 110 rotates, the volume within cavity 118a reaches its minimum value (as shown). Figure 11 As shown), this indicates the completion of the compression stroke. The compressed fluid is delivered via the discharge / exhaust / output rotary valve 206. Its function is to perform a two-stroke process of inlet / intake / input and discharge / exhaust / output between adjacent sides of the cycloidal profile. The number of cycles is equal to the number of sides (n) of the cycloidal profile in the housing divided by two (2). Therefore, the rotary piston machine can operate as a positive displacement pump or compressor when driven by the output shaft.

[0050] See Figure 22 This illustrates an expander / motor. An expander / motor is essentially a compressor / pump (such as...). Figure 21 The rotary piston machine (shown) operates in reverse or inverted modes to drive the output shaft. It includes a housing with rotary valves arranged adjacent to each other. The rotary valves include an inlet / inlet rotary valve 204 for supplying pressurized fluid during the inlet / intake / input cycle, and an outlet / outlet rotary valve 206 for releasing depleted fluid during the outlet / outlet / output cycle. The inlet rotary valve 204 opens during the inlet / intake / input cycle to receive pressurized fluid, while the adjacent outlet rotary valve 206 remains closed. Fluid acts on the rotating assembly, moving it to its maximum volume position, and is then removed via the outlet / outlet. Therefore, the rotary piston machine can function as a motor or expander driving the output shaft.
