Description

New rotary engine

Technical field

In addition, the conventional reciprocating piston engine generates a large interaction force between the piston and the crankshaft during operation, which requires high strength of the piston and the crankshaft. Therefore, it is necessary to increase the size of the piston, the crankshaft and the cylinder. To compensate for the lack of strength, which leads to a relatively large volume of the entire engine.

detailed description

The present invention will be further described below in conjunction with the drawings and specific embodiments.

Embodiment 1:

As shown in FIGS. 1 and 2, a rotor engine of the present invention includes a cylinder block 10, two rocking pistons 30, a rotor 20, and two elastic members (not shown), wherein the inner wall of the cylinder block 10 is The projection on the radial section of the cylinder block 10 forms a circular contour. The inner wall of the cylinder block 10 is provided with a first piston groove 11 and a second piston groove 14, the first piston groove 11 and the second piston groove. The structure of 14 is the same and the two are oppositely distributed on the inner wall of the cylinder block 10, taking the first piston groove 11 as an example, which includes a pivoting portion 111, and a pivot a sliding arc surface 112 opposite to the joint portion 111 and an opening portion on the inner wall surface of the cylinder block 10, the opening portion penetrating the inner chamber of the first piston groove 11 and the inner cavity of the cylinder block 10, and the domain of the second piston groove 14 The structure of the first piston groove 11 is the same and will not be repeatedly described herein.

A combustion chamber 40 is disposed on the cylinder 10 at a position close to the first piston groove 11. The first piston groove 11 of the combustion chamber 40 is communicated through an air guiding passage 43. The combustion chamber 40 is provided with a spark plug 41 and a fuel injector 42. The air guiding passage 43 is a bottom wall 113 having a first piston groove 11 extending into the combustion chamber 40. The combustion chamber 40 is further provided with a gas charging port 44 communicating with the inner cavity of the cylinder block 10, the gas charging port. 44 is located on the side of the sliding arc surface 112 of the first piston groove 11 of the cylinder block 10, that is, the gas charging port 44 is located on the cylinder block 10 near the sliding curved surface 112 of the first piston groove 11. An air inlet 12 and an exhaust port 13 are respectively disposed on the two sides of the cylinder 10 on the second piston groove 14, wherein the air inlet 12 and the exhaust port 13 are arranged in a counterclockwise direction.

Two rocking pistons 30 are respectively embedded in the first piston groove 11 and the second piston groove 14, and the rocking piston 30 cooperates with the first piston groove 11 and the second piston groove 14 in the same manner to the first piston groove For example, the rocking piston 30 includes a rotating portion 31 that is rotatably engaged with the pivoting portion 111, and a fitting block 32 that is tightly and slidably engaged with the sliding curved surface 112. The fitting block 32 forms a fitting end toward the inner side of the cylinder block 10. 36. Specifically, the curved surface 33 of the insert 32 away from the rotating portion 31 is sealed and slidably engaged with the sliding curved surface 112. The swing piston 30 is provided with an intake passage 35 for conducting the chamber of the cylinder block 10 and the first piston groove 11, and the intake passage 35 is specifically adjacent to the bottom wall 113 side of the first piston groove 11 by the swing piston 30. The side wall 34 extends to a surface of the insert 32 near the inner cavity of the cylinder 10. The rocking piston 30 in the second piston groove 14 is mounted in the same manner as described above, and is not here. Repeat the instructions.

The spring element is a spring (not shown) disposed between the cylinder 10 and the rocking piston 30, which springs the insert 32 of the rocking piston 30 toward the inside of the cylinder 10. Of course, the pivoting portion 111 and the rotating portion 31 may be pivotally connected together by a rotating shaft. The elastic member is a torsion spring disposed on the rotating shaft, and a free end of the torsion spring abuts on the rocking piston 30. The other free end is coupled to the cylinder block 10 such that the insert 32 of the rocking piston 30 always maintains a tendency to rotate toward the inside of the cylinder block 10. In short, the above-described elastic member can exert a rocking piston 30 on the rocking piston 30. The elastic deformation of the insert 32 toward the inner side of the cylinder 10 may be sufficient.

The rotor 20 is located inside the cylinder block 10 and is coaxial with the cylinder block 10 and is rotatable clockwise relative to the cylinder block 10. The rotor 20 includes two sealing ends 21 and a sealing end 22 which are slidably and tightly engaged with the inner wall of the cylinder block 10, The sealing end 21 and the sealing end 22 are oppositely disposed, and the outer peripheral surface of the rotor 20 is formed between the sealing end 21 and the sealing end 22 to form a mating surface 23 and a mating surface 24 which are slidably and tightly fitted with the fitting end 36. A sealed chamber is formed between the inner wall of the cylinder block 10 and, similarly, a closed chamber is formed between the mating surface 24 and the inner wall of the cylinder block 10. The rotor 20 may be arranged in an elliptical shape, and the sealing end 21 and the sealing end 22 are two ends corresponding to the elliptical long axis of the rotor 20. The mating surface 23 and the mating surface 24 are respectively the surfaces between the elliptical long axis end points of the rotor 20, and the cylinder body The diameter of the internal chamber is equal to the diameter of the long axis of the rotor 20, thereby ensuring that the sealed end 21 and the sealed end 22 are hermetically fitted to the inner wall surface of the cylinder 10.

When the engine described above is in use, the rotor 20 is rotated in the clockwise direction relative to the cylinder block 10, and when the sealed end 21 and the sealed end 22 are rotated to the rocking piston 30, the rocking piston 30. Under the pressure of the rotor 20, the two rocking pistons 30 are completely accommodated in the first piston groove 11 and the second piston groove 14, and when the sealing end 21 and the sealing end 22 are rotated to other positions on the inner wall of the cylinder 10, the elasticity is 30. Under the action of the components, the abutting ends 36 of the two rocking pistons 30 are tightly fitted to the mating faces 23 and the mating faces 24 on the rotor 20. The above-described engine works as follows. When the sealing end 21 is rotated to the rocking piston 30 (ie, the rocking piston 30 at the lower side in FIG. 1) located in the second piston groove 14, the lower rocking piston 30 is completely accommodated in the second piston. In the groove 14, and the fitting end 36 is tightly fitted with the mating surface 24, the mating surface 24, the sealing end 21, the lower rocking piston 30 and the inner wall of the cylinder 10 are defined as the rotor 20 continues to rotate and just over the inlet port 12. The chamber communicates with the outside through the air inlet 12, and during the continuous rotation of the rotor 20, the volume of the chamber gradually increases, and outside air enters the chamber through the air inlet 12, and the engine begins to inhale. The process, when the sealing end 21 is rotated to the rocking piston 30 (i.e., the rocking piston 30 above in FIG. 1) located in the first piston groove 11, the above-mentioned mating surface 24, the sealing end 21, the lower rocking piston 30, and the cylinder block The chamber volume defined by the inner wall 10 is increased to the maximum, the suction process of the engine is completed, and at this time, the sealing end 22 just rotates to the lower rocking piston 30, and the rotor continues to rotate, and the sealed end 22 just passes over the intake air. Mouth 12 At this time, the sealing end 22 starts to press the gas sucked by the sealing end 21 into the combustion chamber 40. Specifically, the sealing end 22 rotates, and the sucked gas enters the first piston groove through the intake passage 35 of the upper swing piston 30. 11, then enters the combustion chamber 40 through the air guiding passage 43, when the compressed gas completely enters the combustion chamber 40, the sealing end 22 rotates to a position just past the gas charging port 44, at which time the fuel injector 42 is directed into the combustion chamber 40. The fuel is injected, and the spark plug 41 is ignited, the fuel and the compressed air are fully mixed and instantaneously exploded, and the exploded gas is sprayed from the gas charge port 44. Exercising, the work is performed on the sealed end 22 just before, and a moment is applied to the sealed end 22 to rotate it clockwise. The burned exhaust gas is sealed on the sealed end 22, the mating surface 23, the upper swing piston 30 and the inner wall of the cylinder 10. In the defined chamber, when the sealed end 21 just passes over the gas charge port 44, the inside of the combustion chamber 40 explodes for one work, and when the sealed end 21 rotates through the gas charge port 44 and continues to rotate, it can The exhaust gas generated after the working of the sealing end 22 is compressed toward the exhaust port 13, and when the sealing end 22 is rotated to the exhaust port 13, the exhaust gas is compressed, that is, the exhausting process of the engine is completed, and when the sealing end 22 is rotated through the exhaust port 13 At this time, it starts the next inhalation operation, and at the same time, the gas in the combustion chamber 40 performs a work on the sealed end 21. Through the above process, it can be seen that during the one-rotation of the rotor 20 of the above engine, the combustion chamber 40 performs two combustion work, and the two combustion work respectively applies a clockwise rotation torque to the sealing end 21 and the sealing end 22, At the same time, during the one-rotation of the rotor 20, the sealed end 22 and the sealed end 21 perform an intake-pressure-exhaust operation, respectively. The above process has a high consistency. When the sealing end 22 performs the suction, the sealing end 21 receives the injection pressure of the gas and simultaneously performs the exhausting action. When the sealing end 22 completes the inhaling action, the sealed end 21 completes the exhausting. The action starts to pressurize.

In order to prevent the gas from flowing back into the first piston groove 11 during the explosion work, a check valve may be provided in the air guide passage 43, which only allows gas to enter the combustion chamber 40 from the first piston groove 11.

Wherein, the inner wall of the cylinder 50 is in the cylinder The projection on the radial section of 50 forms a closed contour having an upper vertex a and a lower vertex b, and the inner wall of the cylinder 50 is formed between the upper vertex a and the lower vertex b. An arc-shaped mating surface that protrudes toward the outside of the cylinder 50, that is, an arc-shaped mating surface 53 and an arc-shaped mating surface 54; in fact, the inner cavity of the cylinder 50 can be arranged in an elliptical shape, that is, the above-mentioned closed The contour line is elliptical, the upper vertex a and the lower vertex b are both ends of the short axis of the ellipse, and the arc mating surface 53 and the arc mating surface 54 are actually portions between the ends of the elliptical short axis, of course, the above The closed contour may also be other shapes as long as the radius of the arc-shaped mating surface 53 and the curved mating surface 53 is gradually changed.

A combustion chamber 80 is disposed on the cylinder block 50. The combustion chamber 80 is internally provided with a spark plug 81 and a fuel injection nozzle 82, and an intake passage 84 and a gas gas communicating with the inner cavity of the cylinder block 50 are respectively disposed on both sides of the combustion chamber 80. The intake port 83, the intake passage 84 and the gas charge port 83 are respectively located on both sides of the upper vertex a; on the cylinder block 50, an intake port 51 and an exhaust port 52 are respectively disposed on both sides of the lower vertex b, and the intake port is respectively provided. Both the port 51 and the exhaust port 52 communicate the inner cavity of the cylinder 50 with the external environment. In the clockwise direction, the intake passage 84, the gas charge port 83, the exhaust port 52, and the intake port 51 are in the cylinder block 50. The inner walls are arranged in order.

The rotor 60 is located in the interior of the cylinder 50, which is coaxial with the cylinder 50, and the rotor 60 is rotatable about the central axis of the cylinder 50 in a clockwise direction during operation of the engine. The rotor 60 may be circular with a radius For r, the radius at the upper vertex a and the lower vertex b of the cylinder 50 is also r. The outer peripheral edge of the rotor 50 has two piston grooves 61 distributed in a circumferential array. The piston groove 61 includes a pivot portion 611, a sliding arc surface 612 opposite to the pivot portion 611, and an opening portion on the outer peripheral surface of the rotor 60.

The rocking piston 70 and the rocking piston 90 are identical in structure and shape, and are respectively embedded in the two piston grooves 61. For example, the rocking piston 70 includes a rotating portion 71 that is rotatably engaged with the pivoting portion 611, and a block 72 that is tightly and slidably engaged with the sliding curved surface 612. The side of the insert 72 facing the inner wall of the cylinder forms a fitting end 73 that is sealed and slidably engaged with the arc-shaped mating surface 53 and the curved mating surface 54. 72 has a pressure receiving surface 74 facing the gas charging port 83 when the rocking piston 70 is rotated to the gas charging port 83. The pressure receiving surface 74 may be a surface of the insert 72 that is slidably engaged with the sliding curved surface 612. It may be other faces that are placed on the insert 72.

When the engine described above is in use, the rotor 60 is rotated clockwise about the central axis of the cylinder block 50, and when the rocking piston 70 or the rocking piston 90 is rotated to the upper vertex a and the upper vertex b of the cylinder 50, the rocking piston 70 and The rocking piston 90 is pressed by the inner wall of the cylinder 50, which is completely embedded in the two piston grooves 61, respectively, when the rocking piston 70 and the rocking piston 90 are rotated to the arc-shaped mating surface 53 and the curved mating surface 54, at the centrifugal force The abutting end 73 of the rocking piston 70 and the rocking piston 90 is pressed against the curved mating surface 53 or the curved mating surface 54, that is, the inner wall of the cylinder 50 is hermetically fitted. The above-described engine works as follows. When the swinging piston 70 instantaneously rotates just past the intake port 51, the pressure receiving surface 74 of the rocking piston 70, the rotor 60, and the closed chamber enclosed by the inner wall of the cylinder 50 pass through the air inlet 51. In communication with the external environment, at this time, in the process of sliding the rocking piston 70 clockwise from the air inlet 51 to the intake passage 84 along the arc-shaped fitting surface 54, the pressure receiving surface 74 of the rocking piston 70, the rotor 60, and the cylinder The volume of the closed chamber enclosed by the inner wall of the body 50 is gradually increased, thereby sucking air in the external environment into the closed chamber, and when the rocking piston 70 just rotates to the upper vertex a, the inhalation process is completed, and At the same time, the swing piston 90 just turns Moving to the lower vertex b, in which the rotor 60 continues to rotate, the swing piston 90 compresses the air sucked by the swing piston 70, and when pressed into the combustion chamber 80 through the intake passage 84, the swing piston 90 just rotates. When the intake passage 84 is reached, the compression process is completed, at which time the swing piston rotates to a position just past the gas charge port 83 in a small time, and the pressure receiving surface on the rocking piston 90 faces the gas charge port 83, the combustion chamber 80 The internal fuel injection nozzle 82 injects oil while the spark plug 81 is ignited, so that the compressed air and the fuel injected by the swing piston 90 instantaneously explode, and the gas is flushed out from the gas charge port 83, and a large pressure is applied to the pressure receiving surface of the rocking piston 90. Thereby a moment is applied to the rotor 60 that causes it to rotate clockwise. When the swing piston 90 is rotated from the gas charge port 83 to the exhaust port 52, the swing piston 90 is completed, and at the same time, the swing piston 70 is rotated to the intake passage 84 to complete the compression process, and the rotation continues, and the swing piston 70 just passes over the gas. At the charge port 83, the combustion chamber 80 is burned again to perform work on the swing piston 70. At the same time, the swing piston 70 can press the exhaust gas generated after the swing piston 90 is completed from the exhaust port 52, and when the swing piston 70 rotates to the exhaust port At the 52nd place, the work is completed, and the exhaust gas generated after the completion of the swing piston 90 is also completely pressed out. In the above process, the combustion chamber 80 performs two combustion work for each revolution of the rotor 60, and the gas pressure generated by the two combustion work exerts a large pressure on the pressure receiving surfaces of the rocking piston 70 and the rocking piston 90, respectively, thereby generating one respectively. The torque for rotating the rotor 60 clockwise, while the rotor 60 is rotated one revolution, the swing piston 70 and the swing piston 90 perform an intake-pressure-exhaust operation, respectively, with high consistency.

In order to ensure that the internal pressure of the piston groove 61 and the internal pressure of the cylinder 50 are constant, the rocking piston 70 and the rocking piston 90 can be tightly fitted to the inner wall of the cylinder block 50, and can be swayed. The plug 70 is provided with a communication hole 75 extending from the outer side surface of the rocking piston 70 to the inner side surface of the rocking piston 70, thereby communicating the inner cavity of the cylinder 50 with the piston groove 61, thereby avoiding the pressure difference and causing the rocking piston 70. Rotation to the inside of the rotor 60 ensures that the abutting end 73 of the rocking piston 70 is tightly fitted to the inner wall of the cylinder 50; similarly to the above, the rocking piston 90 is also provided with a communication hole.

It is also possible to install a one-way valve in the intake passage 84, which is only used for gas to enter the combustion chamber 80 from the chamber of the cylinder 50, in order to prevent some of the gas from being exhausted after the combustion chamber 80 is exploded. Channel 84 enters the interior of cylinder 50.
