Description

[Detailed description of the invention] Two plate uni TECHNICAL FIELD This invention relates generally to rotary internal combustion engines, and more particularly to increasing fuel economy and power output thereof. Regarding improvements to bring about.

Widely used today, the body has a rotatable piston connected to a rank shaft. In conventional reciprocating piston engines, the piston stroke is limited by the trajectory of the crankshaft. It will be done. As a result, each piston's combustion or power stroke is as large as its compression stroke. Therefore, when the cylinder exhaust valve opens, unused fuel and gas Since it is emitted into the atmosphere, there is a loss of usable power. In such an engine, the same Similar constraints occur on the crankshaft orbit during the exhaust stroke. In other words, the exhaust gas The amount of time it takes to be expelled from the body is limited. As a result, each piston is Loss of output occurs due to back pressure when moving from a high point.

In addition to the above-mentioned limitations on starting and exhaust strokes, such engines fuel mixture and by using a long manifold to distribute the mixture to A decrease in distribution efficiency occurs. This mainly involves periodically opening and closing the intake valve to the cylinder. This arises from necessity, and the inflow of the mixture into the cylinder is then interrupted. this causes non-uniform mixture supply and combustion to and within the individual cylinders. This results in uneven engine rotation.

Another disadvantage of conventional 4-stroke engines is that each piston and cylinder operates in 4 cycles. that requires two revolutions of the crankshaft for suction, compression, combustion, and exhaust. There is. In other words, there is only one combustion or starting stroke for every two rotations of the crankshaft. Doesn't exist. This increases the engine speed for the required power and therefore This results in friction losses and wear and tear on moving parts. Conventional 4-stroke internal combustion engine Engines have springs that are subject to compression, bearings and cams that rotate, or that are subject to forceful sliding. using parts that generate a lot of friction, such as seals that restrict engine rotation. Therefore, the resulting loss in rubbing power cannot be used for horsepower output.

In addition, currently known four-cycle internal combustion engines have the ability to produce maximum power with minimum fuel consumption. Although there are factors and impossibilities that prevent the invention from occurring, the above-mentioned ones are the ones that the present invention These are the basic drawbacks that we aim to alleviate.

In particular, the present invention is characterized in that the pistons extend radially with respect to the axis of rotation and each carry a piston therein. - or a generally cylindrical rotor having a plurality of vertically spaced cylinders; , a stationary main bearing support shaft means disposed coaxially with the rotor; and a concentric ring within the rotor. a combustion chamber mounted in a shape and rotatable integrally with the rotor around the shaft means; cam means for providing a symmetrical continuous curved cam track means; a cam rider assembly means that follows the shape; and a cam rider assembly means that follows the shape; coupled to the pistons in the cylinder, each said piston cooperating therewith along said track means; coupling means for moving radially relative to the rotor in response to a following movement of the rider assembly; To provide an internal combustion four-stroke rotary engine consisting of:

The movement of the various pistons relative to their respective cylinders is controlled by asymmetric cams for this purpose. Because of the means used, it is not constrained by the trajectory of a fixed crankshaft.

As a result, the piston strokes for various cycles of suction, compression, combustion and exhaust are It is selectively changed by changing the cam shape, and the stroke length and time are no longer the same. . Thus, the combustion or power stroke and exhaust stroke are significantly larger than the intake and compression strokes. be done. Since the starting or combustion stroke is increased, the engine has less usable combustion gas. It has the ability to generate more usable output. This activation Stroke increase is limited by the overall size of the engine and the available combustion compressed gas. It's just that. As a result, virtually all compressed gas is removed to the outside of the engine. Can be used to generate force. At this point, the moving belt is the limited length of the crankshaft raceway radius. This contrasts with traditional crankshaft engines, which are limited by

A corollary to the increased power stroke is that the engine uses more pressurized combustion gases. It can be completely converted into a transfer horn, which means that the force or pressure of the combustion gas is smooth. This is due to direct contact with the slope of the cam means which gradually slopes. thus gas is the most efficient lever ratio for the lever ratio used to rotate the cylinder block. used. The long cam angle provides a constant, clean, and lever-operated rotational output. used for the purpose for which it occurs.

As the gas pressure increases, the cam lever ratio changes from the minimum value as the pressure of the expanding gas decreases. It gradually increases over time. This opposing action converts linear piston movement into rotational movement of the output shaft. A substantially constant force is applied when converting to , thus improving engine characteristics. .

Once the pressure of the combustion gases is consumed, the exhaust gases must leave the engine. , since the engine of the present invention uses cam-operated piston motion, the cam angle can be changed here as well. In exhaust mode it can be reduced, allowing the exhaust gas to escape from inside the cylinder. can give you maximum time. As a result, the back pressure on the piston is reduced, Therefore, the loss caused by this factor is reduced.

Not only has the starting and exhaust stroke been improved, but the design uses a cam-operated screw. It also improves the engine's breathing behavior during the intake cycle. This means the engine is stationary Rotates around the manifold and main bearing shafts, resulting in flow into the engine cylinders. This is due to the almost constant or uninterrupted supply of fuel and air. This improved The suction action improves the distribution of fuel in the mixture, resulting in less combustion within the cylinder. The grilling becomes even more powerful.

The preferred engine design provides all four cycle modes of fuel combustion and exhaust. are each completed within 360° of rotor rotation. Therefore rotating cylinder tab Each cylinder of the lock assembly is fired during each revolution of the cylinder block rotor.

As a result, the engine can generate more power or even at lower revolutions per minute. Conversely, by appropriately changing the damping means and piston stroke length, low output can be achieved at high rotational speeds. It can also be used to generate force.

In addition to breathing, iIA combustion, and output, this engine also takes into account internal output loss due to friction. However, it has very big advantages. This allows the engine rotor to rotate freely on precision bearings. and since the cam means are coupled to the individual pistons of the engine, most This is because there is no friction.

Furthermore, the 〇-ta cylinder block of this engine can rotate relatively freely, making it extremely exhibits a strong flywheel effect, resulting in the engine operating at higher than its short-term rated capacity. can generate output. For example, this characteristic is especially important when starting a car, etc. This is useful when the engine is engaged with the drive shaft. This flywheel effect The result is reduced engine size in automotive and other applications to reduce power requirements to save fuel. It also makes it possible to reduce the amount.

The rotor means 50 is essentially a cylindrical flywheel cylinder block, - or a plurality of cylinder bores are arranged along a radial axis spaced apart from each other with respect to the chord direction. A piston cylinder is formed. In the illustrated embodiment, four such radial Disposed piston cylinders 6C65°66 and 67 are provided. Possible Siri The number of bore holes in the rotor depends on the space available in the rotor and the requirements for a particular engine power. It is important to note that this is determined only by Within the scope of such factors, the present invention The engine may consist of one or more cylinders. Adjacent to each cylinder bore and a pair of shapes extending parallel to it on both sides of the front and back sides of the rotor. Congruent, parallel spaced cam sliding grooves 68,68 are provided for each piston means 56. A pair of cam rider assemblies 58 are received in cooperation with the cam rider assemblies 58.

It is formed. Alternatively, such intermediate areas may remain solid if desired.

The cylinders 64 to 67 freely communicate with the outer periphery and six central inner holes of the rotor 50, respectively. It will be understood that this is true. Also, when configuring the rotor 50, the rotation is around the central axis. Static and dynamic equilibrium of the rotor is achieved by evenly distributing the vibrations during operation. It will also be understood that it will be avoided.

Although not shown, a key is provided in the center inner hole 69 of the rotor for interlocking with the combustion chamber means 52. - Grooves are provided, which will be explained below.

The combustion chamber 52 is a multi-purpose part, supporting the rotor means 50 and also Rotating around the stationary main bearing shaft and the intake/exhaust manifold means 54, which are always connected to each other. (See Figures 3 and 4). As can be seen from FIG. 6, the combustion chamber means 52 is cylindrical. a long key formed by the body portion 80 and engraved on one side parallel to its longitudinal axis; - A groove 81 is provided. The main body portion 80 has an end wall portion 8 that partially closes one end thereof. 2; and the opposite end extends radially outwardly from the circumference of body portion 80. It has an annular flange extending around the circumference of the provided with parallel flanges characterized by notches or cut-out portions 84.84; It is partially closed off by an end wall portion 83. Such cutout portion or notch 8 4 is provided for the purpose of clearing the cam rider assembly 58 during operation, and the following Let me explain in more detail. Two end wall portions 82 and 83 extend through the main body portion 80 and are identical. The stationary main bearing shaft and manifold means 54 are axially extended and are internally pressurized during assembly. The large cylindrical sleeve bearing 86 (see Fig. 4) It is characterized by a central cylindrical bore 85.

The cylindrical body portion 80 of member 52 further extends radially inwardly from the surface as shown in FIG. characterized by four perforated openings 87 communicating with a bore 85 extending into and receiving a solid shaft. Can be attached. Each of the perforations 87 radially intersects the central axis of the member 52 and also includes a notch. They are arranged so that the center coincides with one of the parts 84, and a circle is formed at the outer end. a shallow cup depression having a cylindrical counterbore and thus coaxially aligned with the opening 87; 88 is formed.

Then, the perforation 87 passes through a truncated conical part 89 cut into the cup hollow part 88. It is connected. The radially inner end of each drilled hole opening 87 is the elongated axis of the combustion chamber member 52. It communicates with a horizontally elongated oval opening 90 having a long sleeve parallel to the main axis during assembly. The shaft is inserted through an oval opening 91 formed in the receiver and aligned to match the shape. It communicates with 54. As can be easily seen, the overlapped openings 90°91 are used as valve means during operation. It works. Each of the drilled openings 87 and said adjacent bore areas 88,89 are individually of combustion T, the combustion chamber of which is coaxially aligned with the cylinder when assembled. 64 to one of 67. Combustion chamber and four cylinders 64 to 67 Accurate coaxial alignment ensures that the keys are aligned by keyway means 81 on the outer surface of body portion 80 of member 52. and by engaging with a keyway provided in the central enlarged opening 69 of the rotor. It will be done.

Each combustion chamber includes a combustion chamber extending inwardly from the outer end 82 of member 52 parallel to the longitudinal axis of member 52. A spark plug 92 that is screwed into the drilled opening 93 is inserted: The gapped electrode projects into the combustion chamber formed by the bore portions 87-89 ( The outer end 82 of the member 52 also includes twelve openings 94,94 and 95.95 is provided to coaxially attach the main drive gear 62 to the outer end of the member 52 during assembly. Accepts suitable fasteners for joining. The gear 62 has eight holes on the l wall 82. It is fixed with bolts 96°96 (see Fig. 10), and protrudes outward from the four openings 95. They are arranged according to the positioning bins 97.97. The flame on the opposite side of combustion v52 The end wall portion 83 having a flange is similarly shaped into an annular flange portion as shown in FIG. by eight machine bolts (not shown) extending through suitable openings 98 made in the be combined.

As previously mentioned, accurate alignment of the four combustion chambers and the several cylinders is achieved by the member 52 and the rotor. This is accomplished by engaging a key and keyway means formed in the central bore of the The baking chamber means 52 has keys and keyways arranged and engaged in the six central openings of the rotor as described above. They are then press-fitted together. As a result, the rotor 50, the combustion air means 52 and the main bearing 86 are It is rotatable coaxially about the shaft and manifold means 54.

The intake and exhaust manifolds 54 are connected to a rotatable rotor means 50 and fixed thereto. A general rule for the movement of the adjacent combustion chamber means 52 and the main bearing 86 thereabout. It plays a supporting role. It also supplies the mixture to the individual combustion chambers and from the cylinders. It functions to discharge exhaust gas.

The features of the exhaust manifold means 54 can be better understood from the connection of FIGS. 4 and 7.

As shown in the figure, the portion U54 has an integral collar portion 101 in contact with the negative outer end portion 102. It also has a flat surface 103 for engagement with a wrench and for the purpose of adjustment as detailed below. It consists of a long cylindrical shaft body 100 that can rotate dynamically. At the opposite end 104 of member 54 is provided with a threaded opening (not shown) into which a screw is inserted, which allows the carburetor to Means 26 are coaxially mounted.

As shown at 106 and 108, there are two large coaxial bores at each end of the shaft member 54. It is formed inwardly (see FIG. 4) and extends partially along its longitudinal direction. Inside Hole 106 intersects at its inner end a secondary bore 110 disposed at 45° to its axis. . The outer end of the inclined bore 110 is milled parallel to the longitudinal axis of the member 54. It intersects with the slot or flat portion 113 that has been formed. Similarly, the central bore 108 has two inner ends. It intersects a subsequent inclined bore 112, which in turn intersects a flat portion 114.

The two flats 113 and 114 form exhaust and intake valve boats, respectively. child They never intersect (see Figure 7) and each combustion chamber and adjacent oval Cooperates with opening 90.91.

The shaft 54 also has a plurality of outlets 119 (see FIG. 4) communicating with the main bearing 86. It is also formed for the purpose of sliding when the bearing moves around the stationary shaft 54. An internal lubrication passageway means 118 is provided having a supply fitting 120 in the collar portion 101. I'm being kicked. Joint 120 is connected to oil line 39.

As shown in FIG. The inner hole 108 and the inner hole 112 that intersect therewith direct the air-fuel mixture into the combustion chamber. Forms a main air intake passage system for supplying air to the air. As can be seen from Figure 4, the shaft 54 is coaxial with the main bearing 86, coaxial with the combustion chamber 52 and the rotor 50, and The exhaust and intake boats are inserted in alignment with the pivot axis 54 so that the slot The valve boats 113 and 114 are aligned with the oval opening 90 and corresponding thereto. Openings 91 in the bearing member 86 and the intake of several pistons and cylinders of the engine and align according to the exhaust cycle.

In order to hold the shaft 54 in a fixed and non-rotating state after adjustment, two shaft members 122 and 54 are provided. and 124 are attached and tightened to the outer end of the shaft member 54: the tightening member 122 is attached to the rear The fastening member 124 is also bolted to the engine case wall member 32. Front cover of the auxiliary casing 128 disposed at the center of the front wall member 31 of the housing Attached to wall 126. In this configuration, the rotor 50 is axially connected to the combustion chamber 52. individual combustion chambers aligned coaxially with the expelled cylinders 64-67 moving around 54; 87 moves sequentially to select rotation cycles of boats 113 and 114 and rotor 50. communicated at the same location. The combustion chamber and these cylinders are boats 113 and 114. The cylindrical integral outer wall of the shaft 54 seals and blocks the space between the two. In this way An engine valve system is provided. In this configuration, the intake boat 114 is connected to the engine. It is always in communication with one of the four cylinders, so that the flow of the mixture is controlled by the valve means. uninterrupted, so that passages 108, 112 have a steady flow of air-fuel mixture therethrough. It should be noted that

The piston 56 is integrally constructed as shown in FIG. 30 are integrally formed with the connecting rod and crosshead portions 131 and 132, respectively. It is. The head part is naturally cylindrical, but the crosshead is approximately rectangular. has a semi-cylindrical end that engages the cylinder wall to insert the cylinder into the piston chamber of the piston. It acts as a guide for movement into and out of the chamber. Also in the head part 130 Also provided are three annular rings 134, two of which are compression rings. The third ring is an oil ring that promotes lubrication of the cylinder wall. Li The ring 134 is of course carved for this purpose on the circumference of the cylindrical piston head portion 130. It is installed in a suitable groove provided. The crosshead portion 132 has the length of the piston. A connection extends across the hand shaft and couples the piston to a cooperating cam rider assembly 58. A central cylindrical bore is provided into which a dowel pin 136 is inserted. as explained above In the embodiment shown in , there are four pistons, one for each of the cylinders 64-67. One cylinder is installed in each cylinder, and the cylinder moves coaxially and linearly with respect to the cylinder. , each piston is further coupled to a pair of cooperating cam rider assemblies 58; This will be explained in detail below.

As shown in FIGS. 4 and 8, each of the cam rider assemblies 58 is elongated and double-sided. Parallel spaced straight rail portions 139 are formed that extend along the edge and As explained in , below the lip 70 in the sliding groove 68 provided on both sides of each cylinder. It comprises a substantially rectangular rigid sliding member 138 that is slidably received. kamura As explained earlier, the roller assembly is a means of applying rotational force to the rotor, and this end Connecting pins 136 connect the cylinders from both sides of the crosshead portion 132 of each piston. Each sliding member in a cooperating pair extends outwardly through a slot opening 71 in the wall. It is press fit into a cylindrical opening formed adjacent the outer end of 138. Pin 136 is extending parallel to and spaced apart from the longitudinal axis of main bearing shaft 54 and into slot opening 71 . loosely accepted. The internal connection between pin 136 and sliding member 138 provides a rigid connection between such members. They are sexually connected, so when the sliding members move, the piston also follows its constraints. movement within the range and vice versa. Engagement of rail portion 139 with sliding groove 68 is a loose sliding fit, and the sliding member can easily move along the sliding groove in the rotor. I can do it.

The lower end of the sliding member 138 has a protrusion that protrudes further than the sliding member that cooperates with the sliding member laterally. A mounting bracket to which the pin member 142 is attached and the cam follower roller 144 is attached. Form a tad. Each O-ra 144 is formed adjacent to the outer end of the pin member 142. The snap ring is secured by a snap ring (not shown) received in the snap ring 145. held. Each cam follower roller 144 is inserted into the hub race member by a known method. consisting of an external ring movable around and over a rotatable roller bearing held in the form a standard bearing assembly configuration.

As shown, in the assembly a pair of bearing member rollers 144 are mounted on the head of each piston. A cooperating row 5144 is disposed adjacent to and coaxially connected to both sides of the end portion 130. line up. Each piston thus has a pair of sliding members 138 and cross-connecting pin means 13. It is effectively supported on rollers 144 by a rigid yoke system consisting of 6.

Such a cam rider assembly uses combustion of fuel to engage the piston head in each cylinder. The linear force generated by this is converted into the desired rotational action of the engine block, and the drive gear means 6 This is a means for rotating 2. This conversion action is achieved by the D-Ra bearing, which a piston for forcing it onto a slope provided by cam means 59 and 60; The cam means of the follower roller bearing is pushed outward by a small amount of combustion. The rotation of the rotor assembly 50, which is freely rotating due to the thrust force, responds to the desired result. A rotational output is generated.

The features of the cam means 59-60 are clearly shown in FIGS. 3, 4 and 5. . The cam means 59 and 60 are identical as far as cam shape and construction are concerned, so they are identical. They can be accommodated parallel to each other so that their shapes match, so one side is parallel to the other. It's just a mirror image. Therefore, the following description will mainly relate to the cam means 59. However, it is understood that the corresponding features of the cam means 60 are the same. .

With particular reference to FIGS. 3 and 5, the cam means 59 shown here is A shaft means 54 and a rotor means 50 are arranged coaxially in the rear cover wall 32 of the housing. It consists of a substantially square heavy metal plate 150 which is properly bolted together. Cam means 6 0 is similarly fixed to the front casing wall 31 so as to match the cam 59. Fifth As can be seen better in the figure, the plate 150 is cut out in the center, and the cam follower is rotated during operation. a continuous shaped asymmetric peripheral cam track 152 is formed that engages the roller 144. . In the example shown, the track 152 is configured to allow the piston to perform four different movements. The movement of the piston is along the cam trajectory of the cam roller means 144. This is done in response to the engagement movement.

In summary, the track 152 includes an engine and a cover that coincide with the axis of rotation of the mortar means 50. Two lobe regions 153 and 154 that protrude inward toward the central axis of the damping plate 150 are distinguished. be done. The peak of low 1153 indicates the beginning of the engine piston intake cycle. , is regarded as the O displacement position of the rotor rotational motion. Approximately 8 degrees counterclockwise from this O position Until the 5° position, the cam angle of the track 152 becomes further away from the lower neighbor or engine center axis. , so that each screw 1 is followed by cooperating roller means 144 along track 152. It moves radially outward from the rotor axis of rotation as it moves. This inhalation mode or The elliptical openings 90, 91 . of adjacent bearings. and the combustion chamber is in the main bearing shaft 54. A vacuum atmosphere is created in the cylinder sealing part when the suction boat 112 provided is approached and lined up. to be accomplished. As the rotor moves counterclockwise on the suction boat, the piston moves away from the carburetor. The mixture is inhaled through the intake manifold passages 108 and 112, and the rotor rotates counterclockwise. Gradually increase the suction bow h144 for the cylinders involved when approaching 85° with rotation. close.

It should be noted that the cam means 59 has an auxiliary part designated 156 in FIG. Must be. This is arranged radially inside the suction part of the track 152 and Secondary cam trajectory 1 having a parallel spaced relationship to the cam trajectory 152 of the section Give 58. The corresponding auxiliary plate 160 faces the plate 156 and is pressed so that the shape matches the plate 156. 60 (see FIG. 4). These secondary cam plates are is low, giving the necessary centrifugal force to the piston to make the cam rider assembly follow the trajectory 152 When starting the engine, the air-fuel mixture cannot be sucked into the cylinder sufficiently. It is specifically designed to assist with entry. Auxiliary cam plate in other than starting mode Portions 156 and 160 serve no purpose and are normally used after the engine has been fully operated. It does not engage with the O-ra means 144.

The cam track portion 152 between the end of the suction cycle and the apex of the second loaf 154 (loaf (approximately 85 degrees to 175 degrees measured counterclockwise from the apex) is for each piston. Configure the compression cycle of the cylinder/cylinder assembly.

Compression is carried out by the oval opening 90.91 of the cylinder and combustion chamber of interest being connected to the suction passage 112. The intermediate shaft 54 of the intake and exhaust boat openings passes through the intake and exhaust boat openings. When the opposite side is reached and the cylinder and combustion chamber are sealed and shut off, the explosion begins. Loss of mixture is prevented during compression. The gas is gradually moved by the cooperating cam rider assembly. It is compressed when the cam angle is forced to rise on an upward slope whose value increases. Low As the la means 144 approaches the lobe 154, the piston approaches the centerline of the engine. The compressed air is strongly compressed by υ1, and reaches a fully compressed state at a rotor rotation angle of about 175°.

The next operation of each piston/cylinder following the compression cycle is the combustion mode; occurs between 175° and 237° of counterclockwise rotation. In this mode, the cylinder The piston in the cylinder is fully compressed, and the intake and exhaust boats in the main bearing shaft are sealed. electrically excite the spark plug associated with the particular combustion chamber involved. This ignites the compressed air-fuel mixture inside the sealed cylinder. This happens The piston is then pushed outward from the engine center axis, and the cam rider assembly is at a sharp angle. The rotational drive action of the rotor assembly is generated by the angle of the cam plate descending at an angle of Jiru.

Following the combustion cycle, each piston/cylinder combination in the rotor assembly operates. Enters the exhaust mode of the cycle, which is essentially 237 in counterclockwise rotation. It is done between 360° and 360°. The rotor assembly moves the cylinder into this mode. An oval hole 90.91 in the combustion chamber that cooperates with the exhaust boat 113 in the main bearing shaft. The cam rider assembly is moved along the ascending cam angle, Force the piston gradually inward toward the central axis of the rotor and the top of the loaf 153 Move to target. This corresponds to the movement of the cam follower rotor that cooperates with that of each piston. The inward radial motion moves spent fuel and gases through the exhaust boat and manifold. 106.110. In exhaust mode, the rotor rotates counterclockwise. When the rotation approaches 360°, it is complete and ready to repeat the 4-cycle program described above. Complete.

The above operating cycles or modes of course apply to the four piston and cylinder sets shown. As occurs in each volume, each piston undergoes a complete operating cycle, i.e. suction, Note that compression, combustion, and exhaust occur every 360° of rotor rotation. is necessary. Importantly, the piston stroke and the duration of each operating cycle also depend on the cam trajectory. It is determined by the chosen shape of the road and can vary widely as desired. Ru.

The rotational drive of such a rotor corresponds to the coupled rotation of the main drive gear means 62. The engine power is extracted from the gear means 62.

The characteristics of the main drive gear means 62 can be seen from FIGS. 4 and 9-11.

The drive gear has several functions. First of all, this takes the output of the engine and outputs it to the output shaft. Means 28 is provided with means for feeding. Next this insulates the spark plug and the spark plug Provides a means for carrying an insulator that minimizes power losses. Regarding this latter feature, The drive gear means 62 also directs the spark plug to ignite at the appropriate time of the engine operating cycle. It also acts as a cooperating part with the sequence distributor.

To understand how the functions described above are performed, reference is first made to FIG. this The figure shows the combustion air means 52 assembled in position on the intake and exhaust manifold means 54. The end 82 of the means 54 extends through a suitable opening in the casing wall 31. and extends into the box-shaped auxiliary casing 128 fixed to the front of the engine casing. are doing. The combustion chamber means 52 includes four perforated chambers 93 formed inwardly at the outer end 82. , and in the illustrated embodiment four spark plugs 92 are received therein (the fourth (see figure) may be recalled. The spark plug is attached to the wall of the opening 93 as explained earlier. They are engaged by thread grooves, and the gapped electrode has four series in the illustrated embodiment. are arranged in individual combustion chambers cooperating with each other.

Further, as shown in FIG. 9, the output shaft 28 is installed in the casing wall 31 and in a bearing means 164 which is partially supported by an adjacent cam plate (not shown). , and is rotatably supported thereby.

Referring to Figure 10, the details of the drive gear are shown more clearly. 62 is fixed to the outer end of the combustion chamber 52 by bolt and bottle means 96 and 97 1]- It should be noted that the combustion chamber is a straight gear that rotates with the combustion chamber. drive In parallel with the gear 62, a timing gear 168 is operated by a key and seven-groove means 166 or the like. It is fixed to the output shaft, which in the example shown has the same dimensions as the drive gear. There is. , the two gears mesh with the teeth on the outer periphery and rotate at a ratio of 1:1. This number of teeth The ratio can of course be varied depending on the required rotational speed of the output shaft 28 within a technically possible range. Ru.

The drive gear 62 has four large wheels aligned with the openings 93 in the combustion chamber means 52. It has a wide opening 170, and a center electrode or conductive core member 173 is attached inside. such an insulator portion receives therein a cylindrical insulator 172 (see FIG. 4). The conductive core member 173 is fitted around the outer electrode end of the spark plug, and the conductive core member 173 is fitted around the outer electrode end of the spark plug. As can be seen from the figure, it contacts the connector electrode 174. As a result, the spark plug and I A good and reliable circuit contact is established with the JN-5A member 173. suitable lo a back bolt 175 engages a protruding semicircular end shoulder 176 of each insulator 172; This is locked axially within its bore 170 and the central connecting electrode of the spark plug. Press firmly. With this configuration, the drive gear means 621, the spark plug 92 and The combustion chambers 52 are movable simultaneously about a common axis following the movement of the rotor means 50. be understood.

Some spark plugs are correct according to the combustion operation cycle of each piston of the engine. Adjust the timing of the spark plug firings to ensure that they fire in the correct order. , it is also necessary to provide means for supplying electrical energy to the electrodes. Especially the first As can be seen in Figure 0, for this purpose a layered end 176 at the outer end of the insulator is used for each conductor. A portion of the sexual core member 173 is cut into a half-arc shape, and the arc-shaped cut portion is They are aligned at a common radius from the central axis of shaft 54.

As shown in FIG. 11, on the outer cover 126 of the auxiliary housing 128 there is a A collar 124 is attached, which is bolted to the cover wall 12G as described above. ing. , II lock collar 124 is cut off on the negative side and provided with a straight shoulder; Against Minlk! A conductive distributor contact member 182 is attached to the device insulator and inside. A housing 180 is mounted thereon. The member 182 is connected by a conductor 183 (see FIG. 1). The ignition coil 27 attached to the outside of the engine housing or casing 30 The opposite path of motion of the electrically conductive core member 173 connected and carried by the drive gear. aligned contralaterally.

Another conductor 186 is secured from the coil 27 to the front wall plate 126 of the auxiliary housing 128. break contact assembly 18 mounted on a rotatable adjustable timing plate 188 Connected to 7. Intermittent contact 187 is attached to and fixed to output shaft 28. and is operatively engaged with a timing cam 190 that rotates coaxially with respect to the output shaft. timing Cam 190 has four lobes 1 that engage followers 192 of discontinuous contact assembly 187. It should be noted that 91 is given. In this way, each time the output shaft 28 rotates, the connection is made intermittently. Point 187 is the combustion cycle of the four piston and cylinder assemblies of the engine shown. It opens and closes four times in response to the

The ignition coil is of course connected to a 12 volt power source 38, resulting in an open disconnect contact. When closed, energy is supplied to the electrodes of the distributor assembly and from there to the insulator member 1. A conductive core member 173 held by It is further supplied when spinning with the wheel and passing under the electrode 182. This is electrical energy - each cooperates with a certain time relationship with respect to the rotation of the timing cam 190. distributed to the spark plugs.

Ignition can be advanced or delayed by bolt and slot means 19 as shown in FIG. This can be achieved by rotating the timing plate which is held in position adjustable by 4. Wear. In this way, the ignition of the combustible mixture for each cylinder can be carried out as desired.

Although various basic parts and parts constituting the preferred engine have been explained above, each A unique cam and cam rider assembly that cooperates with the piston allows the piston to Maximum stroke length is possible while keeping the overall dimensions of the gin to a minimum.

A follower roller of the cam rider assembly 58 is mounted adjacent the head end of the piston. a follower roller positioned adjacent to the inner end of the drive member 138; The cam tracks are aligned so that their shapes match, and the force transmission point is the centerline of the engine. as close as possible. This feature only extends the possible piston stroke allows for a steeper cam trajectory during the combustion cycle, allowing the rollers to The rotational speed of the rollers 144 is greatly reduced while engaging and following the track. This enables the engine to generate a large amount of rotational output. Furthermore, the cam [1 member] By providing this, the output that normally occurs when screws 1 to 1 slide on the side of the cylinder can be reduced. The loss is that the piston is guided linearly by the cam sliding member and crosshead. is substantially eliminated, so that no lateral forces are applied to the piston. Piss Since no lateral force is applied to the cylinder, the life of the cylinder is extended, and the piston ring Improves sealing action.

Additionally, it is important to note that the cam trajectory varies and curves over a wide range. this 4-cycle piston/cylinder action: suction, compression.

Combined with the fact that combustion and exhaust all occur every 360° rotation of the rotor assembly. This allows a wide range of variations in the time and length of the piston stroke. It takes The degree of freedom in cycle design allows the engine to produce maximum power with maximum fuel efficiency. make it possible. For example, the intake and compression strokes are the stroke length and time of the combustion stroke. can be halved to fully utilize the expansion gas. Or the exhaust stroke to purge spent gases from the engine for a longer period of time, thereby reducing the flow of gas into the pistons. Back pressure can also be reduced. Such individual cycle changes are essentially due to the cam design. The engine of the present invention can be used with gasoline, diesel fuel, Virtually any rapidly expanding liquid such as alcohol, natural gas, hydrogen, propane, butane, etc. The fuel can be effectively combusted and converted into rotational output.

This engine not only can burn such fuel, but also has a flexible cam design. Therefore, such combustion can be carried out most efficiently.

The combustion cycle can be extended so that the combustion gases are almost completely consumed and the “C exhaust gas pollution is also reduced.

Although the engine embodiments described above are efficient and versatile in operation, we have listed variations thereof as follows. Differences from the engine shown in FIG. 11 are shown in FIGS. 12 and 13. As shown , the deformable engine 200 has corresponding outer casing members 203 and 204, respectively. It has integrally formed stationary cam means 201 and 202. Roller means 14 4 is the outer cam track 205. as explained earlier. In other words, half way from the engine center axis. The other O-ra means 206 engages a cam track provided on the radially upper outer side, while another O-ra means 206 It engages with the upper inner track 207 in the direction. As a result the cam follower system is It reliably responds to the push and pull movements of the piston, and especially when the piston moves from inward to outward. When reversing the direction of motion, the motion is relatively noise- and rattling-free. I sucked it again The input cycle is reliably controlled without relying on centrifugal force as in the case of engine 20. It will be done. Other than the redesign of the outer casing, cam track means and camf assembly components, no changes were made. Exemplary engine 200 is substantially identical to engine 20 in all respects.

FIG. 14 shows the features of a second variant of the one-engine engine described above. That is, this is Two or more engines 2 that can be coupled to a single output shaft 210 It is a collection of 0 or 200. In particular, in this variant embodiment the outer casing 212 is For example, four individual rotors arranged in four quadrants around the central output shaft 210 Means 50 is attached. The rotors are each connected via an intervening speed clutch assembly 216. and is coupled to a central drive gear 214 which is wedged to the output shaft. Each club The clutch assembly is basically a pair of clutches with different diameters attached to a common clutch shaft 222. The gears 218 and 220 that have become engaged with the drive gear 62 of the single engine rotor of gA gear 218 and a common drive gear 214 coupled to a common output shaft 210. It consists of a secondary clutch RM vehicle 220 that is fitted. slip clutch assembly The configuration is that when gear 220 rotates at a faster speed than gear 218, there are two clutch mechanisms. The clutch is completely disengaged.

On the other hand, if the rotational speed of gear 218 increases and becomes equal to the speed of gear 220, the the gears 218 and 220 are locked together and the torque is applied to the output gear 2. 14. It is further transmitted to the output shaft 210. Locking bin or standard Several methods of locking and releasing the drive shaft are known in the art, such as mechanical pressure clutches. Known means exist.

Basically, the collective engine shown in Figure 14 satisfies the requirements regarding maximum horsepower and at the same time Provides an engine that operates at a fraction of the available output and satisfies the requirements during no-load conditions. It is designed to. In summary, the multiple rotary engine of FIG. Two or more engine rotors 50 can be integrated without keeping the rotors selectively independent of each other. allows for incorporation into one common engine. Therefore, the characteristics shown in Figure 14 The engine can be selectively operated at different horsepower output levels. For example, each Assuming that the motor engine can generate 50 horsepower, the same as shown in Figure 14 Engines including a 40-horsepower engine can generate a total horsepower output of substantially 200 horsepower.

If only 100 horsepower is required due to circumstances, only two D-types are needed. , completely stop the operation of the other two, and keep the two rotors stationary while keeping them stationary. It is possible to operate continuously without being hindered by the two rotors. mosquito In such cases, with a stationary rotary engine, the operation of the entire engine is not interrupted. Maintenance, adjustment, or similar operations can be performed. Another example is Ishi, Taira. If the average horsepower requirement is only 50 horsepower, only one rotor is running at a time. There is no need to make any changes, and you can periodically replace the - rotor with another rotor at startup L. The motor can also be kept stationary, thus extending engine life and reducing wear on moving parts. It can also be made more even. In fact, the aggregation engine shown in Figure 14 has a built-in battery. The rotary engine has a mechanical pull-up system, resulting in mechanical Even if the engine fails, other engines are available and ready for use.
