FIG. 29 is an illustration as shown in FIGS. 25-28, in different angular positions of the main rotor without fuel / air supply.
FIG. 30 is a sectional view taken along the line AA of the rotary machine shown in FIG.

  Referring to FIG. 1, these show a rotary inner edge engine 10, which is constituted by an engine body 11 having a housing wall 8. The engine body 11 is formed by a main rotor member 14 and a satellite rotor member 12.

  The rotor block is suitably connected to an end plate (not shown in this example but similar to 151, 153 in the second example of FIG. 7), and the block 9, plates 51 (151) and 53 (153 ) Encloses engine space 15. The end plate is held in the space and sealed to the main body with four bolts 77 (177 in FIG. 7). Furthermore, end plates 51 (151) and 53 (153) rotate around block 9 in harmony with main rotor 14 with rotors 12 and 14 (or 112 and 114) via their respective axes. The satellite rotor 12 rotates at a different rate from the main rotor, and is shielded by slipping contact between the end plates 51 and 53 and the satellite rotor 12. The end plates 51 and 53 are accompanied by a shaft for a gatrain (shown as 160 in the second example of FIG. 7), which determines the rotational relationship between the satellite rotor 12 and the main rotor 14.

  The upper peripheral wall 32 further forms an upper convex portion of the cavity, similarly to the lower peripheral wall 34, forms the lower convex portion of the cavity 15, and is arranged between the two convex portions 42, 44. Peripheral walls 32 and 34 are generally trochoid, epitrochoid, cycloid, and more specifically determined by the following equations;

θ、R₁ 、R₂およびR₃の定義は図３、図１０および下記により見い出される。
θは、時計方向でのロータの変位角を示し、12時の位置が零でスタートである。

The definitions of θ, R ₁ , R ₂ and R ₃ can be found in FIGS. 3, 10 and below.
θ represents the displacement angle of the rotor in the clockwise direction, starting at the 12 o'clock position of zero.

R ₁ indicates the radius of the main rotor member (the distance from the center to the convex peripheral wall).
R ₂ represents the radius (distance from the center to the top) of each rotor member.
R ₃ is the distance from the center of the main rotor to the inner peripheral wall of the cavity at θ = 0.

  The main rotor member 14 and the satellite rotor member 12 are disposed in the cavity 15. The main rotor member 14 is mounted on the shaft 16. The gatrain (not shown in this example, but in the other preferred example shown in FIG. 7 a similar member is shown at 160) is connected to the main rotor member 14 and satellite member 12, In the example configuration, the satellite rotor member 12 rotates at a 1/3 rotation ratio of the main rotor member 14 and the two rotors rotate in opposite directions.

  The main rotor member 14 has a peripheral wall 7, which generally includes a circular (or partially circular) and arcuate wall 13, which forms a curved portion 17 in the main rotor member 14. The satellite rotor member 12 is disposed in the curved portion 17 for partial rotation and is mounted on the shaft 18.

  Two vents 30 and 28 are provided for the purpose of flowing working fluid to 30 and from 28 to the control chamber. In FIG. 1, 30 is a suction hole and 28 is an exhaust hole.

The satellite rotor member 12 is generally triangular and each side is concave. The satellite rotor member 12 has three apexes 4, 5, 6 that are always in confidential contact with the inner peripheral wall of the cavity 32 or 34 or the rotation thereof around the cavity. The number of separate control chambers is formed as follows. That is, the satellite rotors 36, 38 and 40, the curved portion 17, and the walls 32 and 34 around the cavity. Examples of control chambers are shown at 70, 72, 74, 76, 78, 80, 82, 84 and 86. The satellite rotor member 12 provides a balance between the contour spacing of the perimeter cavity 7 and the high compression ratio by making the chamber as small as possible at the start of the power stroke (typically TDC in Otto cycle terminology). Shape.

  A spark plug is provided at 26 for working fuel ignition. Cooling is done through holes (not shown) in the wall of the main body 9.

  To illustrate the rotary machine in operation, we understand the control chamber through the operating cycle, a series of stepping cycles of FIGS. 1 (i) to (viii). The operating cycle is the basis of the well-known Otto cycle, which is a suction, compression, power and exhaust stage.

  In operation, the main rotor member 14 rotates clockwise around its shaft 16, and in FIG. 1 (i), the control chamber 70 is in fluid communication with the suction hole 30, and the working fluid is controlled through the suction hole 30. It is drawn or pushed into the chamber. The satellite rotor member 12 rotates about its shaft 18 counterclockwise to the position shown in FIG. 1 (ii), and the top 5 closes the suction hole of the control chamber and extends to 72. The control chamber is not in fluid communication with the suction hole and the compression cycle begins for this chamber.

  In operation, in the case of an internal combustion engine, the explosive force caused by the ignition of the working fluid in the control chamber is supported by the shaft on which each satellite rotor is mounted. Ignition occurs once when the satellite rotation axis exceeds the axis extending between the main rotor member central rotation axis and the spark plug. In this case, all torques are in the requested direction.

  FIG. 1 (iii) shows the compression cycle in a slightly advanced state, and FIG. 1 (iv) is almost complete. FIG. 1 (v) shows a complete compression cycle, extending to numeral 78, which is the smallest area in the operating cycle.

  FIG. 1 (vi) shows the initial part of the operating cycle and is the power part at the start of the work cycle. That is, here, the spark plug 26 ignites the working fluid.

  FIGS. 1 (vii) and (viii) show the power cycle that has been advanced to the end. Returning to FIG. 1 (i), the control chamber extends to numeral 86 and is in fluid communication with the exhaust hole 28, and the power cycle ends and the exhaust cycle begins. The triangular shape of the satellite rotor takes in only fresh air mixed with fresh air and does not allow fuel, air, or fresh air to exhaust into the exhaust holes. Only the fuel consumed in the control chamber is mixed with the fuel consumed or exhausted directly to the exhaust hole. This is particularly effective and advantageous in multi-satellite configurations where the interaction is complex.

  Another feature of the triangular satellite rotor member is that one chamber is partitioned by a satellite wall that serves as a storage function. This is because only two of the chambers partitioned by satellite form part of the Otto cycle. However, as already explained, when the storage chamber is in the Otto cycle, the consumed fuel and the fresh fuel will not mix even if they reach the exhaust (the consumed fuel returning to the suction hole is sent). not good). Similar advantages are obtained with the use of pentagonal satellite rotors (not shown). Space in the engine block is more useful than in other rotary engines. This is because higher compression ratios and larger working volumes can be used.

  As noted by the machine's geometric test, in the first form they are supplied with one power cycle for each rotation of the main rotor member, so that the satellite rotor 12 is rotated around the main rotor member for each rotation. 1/3 of a turn. However, the numbers on the satellite rotor member are only effective to continuously view the cycle from 1 (i) to 1 (viii), and are not regarded as a loop of the cycle from 1 (viii) to 1 (i). That is, the tops 4, 5 and 6 represent the periphery of the rotor at each final rotation of the single main rotor member 14. It seems that an empty chamber goes around the main body 9 and there is no fluid.

2 to 8, these show a rotary machine with a twin satellite engine which is another example of the present invention. Features of the form described in the first embodiment are indicated by the same numbers. The configuration in the latter figure has two satellite rotor members 112, 112B and provides two power cycles for rotation of the main rotor component 114 with greater potential for balance and efficiency. First, similarly to the embodiment, the satellite rotors 112 and 112B rotate by 1/3 rotation for each single rotation of the main rotor component 114. The rotation of the satellite rotors 112 and 112B is determined by a gai train indicated by 160 in FIG.

  FIG. 6A is a front sectional view by hatching of the second embodiment, and the gear is attached to the satellite rotor member and the main rotor member. FIG. 8 shows another embodiment, and the rotary machine is a rotation connection between the main rotor member 114 and the satellite rotor without gears (160 in FIG. 7). According to a more advanced concept, the satellite rotors 112, 112B do not require gears to couple their own rotation of the main rotor member 114. This is because the pressure on one side of the satellite rotor that forms part of the control chamber through a power cycle (eg 180 in FIG. 2) will be constant and there will be no lower rotation that occurs when determined by gear 160. If the burned (or other) gas attempts to flow out of the control chamber, such as between the seal 95, 96 or 97 and the peripheral wall 132, it is limited. This is because there is no inflow from any other aperture (eg, the seal / main rotor interface at the flow changing portion 99). A superior feedback system made in this way improves the outer walls of the cavities 132, 134 by roughing or polishing. The amount, price and complexity of the rotary machine is significantly reduced by removing the gai train.

  FIG. 9 (i) is a detail of the satellite rotor member, which is preferable for the use of twelve satellite rotary machines shown in FIGS. The satellite rotor 12 usually has three working sides, which are triangular. However, the top is flattened and formed at the end of a snubber or square instead of a dot, and each square apex is fitted with a seal 96,97. This snubber satellite improves the sealing angle against the arc by the seal and the cavity wall, in order to obtain a sealing effect.

  FIG. 9 (ii) shows a satellite rotor member, which is used in the satellite rotary machine 1 or 2 and has a triangular shape and three seals fitted on each top.

  FIGS. 10 to 12 show 12 rotor embodiments of the machine according to the invention, the features being represented by the numbers of these embodiments already mentioned.

ここで、αは図９（i）、およびこの態様において0.0873 radと定義する。
Ｒ＝ Ｒ₃−Ｒ₂ （Ｒ2とＲ3は既に定義してある）。 The peripheral wall is composed of 12 protrusions 232, which are formed by the following equation in Cartesian plane:

Here, α is defined as 0.0873 rad in FIG. 9 (i) and in this embodiment.
R = R ₃ -R ₂ (R2 and R3 Aru already defined).

  The previous embodiment (FIGS. 1-8) represents a power cycle, which utilizes approximately 180 degrees of rotation of the main rotor member 114, and in this example power cycle, for the full power phase, the main rotor member. Only about 30 degrees is used. There are six simultaneous power stages, and each satellite rotor member supplies power to the main rotor member 214 for one rotation and guides power more smoothly than the other modes.

  13 and 14 show front side cross sections of a rotary engine according to the 12-rotor mode. FIG. 13 shows a cross section without a gator train, the system uses the above-described advanced feedback for the rotation of the satellite rotor, and FIG. 14 shows a gear 260 and a ring gear.

  Another aspect of the rotary machine is shown in FIG. 15 and is in the form of a pump. The main rotor is driven clockwise by a power source (not shown) due to the flow force from the suction holes 330 to the exhaust holes 328, and the satellite rotors 312 and 312B are forced to flow to the exhaust holes 328 on their downstream side 338. Is used. A pipe actuating part (not shown) directs the flow from the exhaust hole 328 to a desired position.

ここで、Aは図１６にて定義され、αは図９で定義される。 Another form of the invention is shown in FIG. In this example, the main rotor 414 is elliptical and its peripheral wall is formed by:

Here, A is defined in FIG. 16, and α is defined in FIG.

  In this shape, the peripheral walls 432 and 434 of the cavity 415 are circular, and the wall of the curved portion 417 is similarly circular or arcuate. This configuration further includes two satellite rotor members 412, 412 B and is coupled to the main rotor 414.

  The operation of the main rotor 414 is clockwise rotation, and the satellite rotors 412 and 414B rotate counterclockwise at a rotation ratio 1/3 of the main rotor 414. Four control chambers are formed throughout the engine operating cycle. As shown in FIG. 16, the two chambers 485, 488 have the smallest possible volume. The working fluid in the chamber 488 is ignited by a spark plug 426B mounted in an inside plate (not shown). Chamber 487 retains suction 428 and fluid communication at the end of the suction stage. Chamber 485 is in fluid communication with exhaust hole 430 upon completion of the exhaust stage. Chamber 486 is at the substantial end of the power stage.

  FIG. 17 is in a later stage than that shown in FIG. 16, and each chamber is indicated by an A in FIG. As can be seen, chamber 487A is a compression stage, 488A is a power stage, and 486A is an exhaust stage.

  As noted, this latter example shown in FIGS. 16 and 17 has two power strokes for rotation of the main rotor 414, rotating recesses 428 and 430 and two apart spark plugs 426 and 426B. There is.

  The example shown in FIGS. 18 and 19 is a triple satellite engine or pump according to another preferred embodiment of the invention, the engine including four tops in the main cavity. Repeatedly, the numbers indicating the parts related to other engines and pumps are described here. In addition, the operation is similar to that of other example engines and pumps.

  Figures 25-29 show another preferred embodiment of the invention where the engine or pump has four satellite rotors and four tops in the main cavity. The operation and configuration are similar to the other engine and pump examples described here, and the numbers also indicate the parts. The satellite in this example rotates 1 and 1/3 times the angular velocity of the main rotor. Referring to FIG. 22, they show a piston element having a seal assembly, which is suitable for use in a rotary engine or pump as described above at 345. The seal assembly 345 is mounted on the satellite rotor 312 as described above, and the satellite rotor 312 has a triangular main body. The main body has three concave main walls, and the extent of the concave surface is such that the satellite rotor 312 has a spoke-like appearance. A seal assembly is disposed within each spoke.

  The satellite rotor element 312 rotates about its central axis 319, each spoke on the rotor 312 has two tops, the sealing elements are located in the individual apertures, and each aperture itself is at the top. At least one sealing element is a cooperating wall (not shown in this figure, but the wall is, for example, the cavity perimeter 32, 34 described above) to form a control chamber (not shown) Maintain an airtight contact with the curved periphery 13 or the like).

  The two tops per spoke are used to maintain an airtight contact between the rotor and the cooperating wall when the cooperating wall is reduced in scope. However, satellite rotors with one top per spoke are useful for seal assemblies. The two-top system has better sealing performance than the one-top seal as the range decreases. It maintains a range where the angle between the surface of the seal and the surface of the cooperating wall exceeds about 30 degrees. If the seal angle falls beyond this number, the sealing effect is lost. 90 degrees between the seal and the wall is ideal for sealing, but this style of rotary engine sealing angle varies with the movement of the operating cycle.

  The seal assembly 345 includes a pair of seal elements 347, 349 mounted on a carriage 359 and is mounted in a housing 363 that reciprocates along each spoke of the carriage 359. Carriage 359 is suitably coupled to biasing means 355 within the helical compression spring 367 contour. Seal elements 396, 397 are biased to extend outwardly from aperture 361 at the top of each spoke to maintain hermetic contact with the wall through the area of seal elements 396, 397.

  Referring to FIG. 23, it shows a side view of the rotor element 412 in cross section, and the rotor element includes two regions 413 and 415 that are adjacent to each other but have a space along the shaft 418 that rotates by itself. Includes a main body. The arrangement between the two region portions 413 and 415 is based on the bias means 471 formed on the leaf spring. In this manner, the end face of the rotor is intimately engaged with the engine sidewall on which the rotor is located, and the rotor end wall maintains an airtight engagement with the engine sidewall regardless of engine thermal expansion or contraction.

  Referring to FIG. 30, a preferred embodiment of an internal combustion engine is shown, which is similar to the other preferred examples already described, the same numbered satellite rotor 612 and the main rotor cooperating therewith. FIG. 30 shows the side walls 651, 653 along the cavity peripheral wall 634 and includes a plurality of control chambers. The side walls 651, 653 are mounted on the main rotor shaft 616 and rotate therewith. In this example, the side walls 651 and 653 are fixed to each other by four bolts, one of which is indicated by 677, and each bolt passes through a cooperating hole in the main rotor 614 (12 cylinders in the case of 12 cylinders). There are bolts). In this way, the mandrel supporting the satellite rotor 612 is mounted on the side walls 651 and 653 so that the satellite rotor maintains its orbit and its own rotation about its own axis 618 is away from the axis of rotation of the main rotor 616. ing.

  The side walls 651 and 653 are hermetically in close contact with the rotor block 609 by the seal 635 when the rotor block 609 is rotating. In this example, the engine housing including the end walls 650, 652 is stationary and the engine is mounted and bolted, while the actual action is inside the side walls 651, 653 of the motor block that rotates with the measure rotor and shaft.
