Description

[Technical field]

[0001] This invention relates to a reciprocating engine that does not involve explosive combustion, but rather uses only the repulsive force of permanent magnets to move pistons and turn cranks to obtain power. [Background technology]

[0002] In recent years, air pollution caused by the use of chemical fuels and environmental destruction caused by resource development have become problems, and one example of a solution to these problems is the piston engine described in Patent Document 1.

[0003] The piston engine of Patent Document 1 has a permanent magnet embedded in the tip of the piston head and an electromagnet attached to the end of the cylinder, and the direction of current flow to the electromagnet is changed as appropriate to cause alternating attraction and repulsion between the electromagnet and the permanent magnet, thereby causing the piston to move back and forth. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2007-74806 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the piston engine described in Patent Document 1 requires power to switch the direction of current flow to the electromagnet, which does not contribute to energy conservation. In addition, a control mechanism is required to switch the direction of current flow to the electromagnet, which makes the device complicated.

[0006] In view of the above problems, the present invention has an object to develop a highly efficient reciprocating engine that uses electric power as an auxiliary power, relies primarily on the power of permanent magnets, has a simple structure, and does not require complex control. [Means for solving the problem]

[0007] The piston engine of the present invention comprises a cylinder having an open top and a crank mechanism therein, a top lid that opens and closes the opening of the cylinder and rotates around one end of the lid as a support axis, an auxiliary cylinder arranged on the side of the cylinder, a main shaft that moves linearly within the auxiliary cylinder, a crank joint that connects the main shaft and the top lid and converts the linear motion of the main shaft into rotational motion of the top lid, and a control mechanism that includes a cam that is arranged coaxially with the rotation axis of the crank mechanism and rotates in sync with the rotational motion of the crank mechanism, and controls the linear motion of the main shaft by means of the cam, and is characterized in that permanent magnets of the same polarity are arranged in the top lid and the crank mechanism.

[0008] With the above configuration, the top lid and the crank mechanism are respectively provided with permanent magnets of the same polarity, so that the cylinder is in an open state. When the cam rotates from this state, the control mechanism controls the linear motion of the main shaft by the cam, so that the main shaft moves vertically downward in a linear manner. As a result, the top lid closes the opening of the cylinder. Since the top lid and the crank mechanism are respectively provided with permanent magnets of the same polarity, the crank mechanism also moves vertically downward in a linear manner due to the repulsive force of the magnets, so that the crank mechanism rotates. Then, the crank mechanism moves vertically upward again, and the top lid opens in a linear manner due to the repulsive force of the magnets. At this time, the cam, which is arranged coaxially with the rotating shaft of the crank mechanism, also rotates, so that the control mechanism again moves the main shaft vertically upward in a linear manner, so that the above-mentioned motion is repeated. By repeating this motion, the crank mechanism can be rotated even without fuel, and a highly efficient piston engine can be realized with a simple structure and without complex control. Effect of the Invention

[0009] The present invention can provide a highly efficient piston engine that uses electric power supplementarily and relies primarily on the power of permanent magnets, has a simple structure, and does not require complex control. [Brief description of the drawings]

[0011] Hereinafter, the piston engine of the present invention will be described in detail with reference to the drawings. It should be noted that the embodiment described below is merely an example of the present invention, and the present invention is not limited to this embodiment.

[0012] First Embodiment

[0013] A piston engine 1 in a first embodiment will be described below with reference to FIGS. 1 to 4.

[0014] As shown in FIG. 1, the piston engine 1 in the first embodiment is equipped with a cylinder 3 having an open top and a crank mechanism 2 therein, a top lid 4 that opens and closes an opening 3a of the cylinder 3 and rotates around one end of the cylinder 3 as a support axis, and as shown in FIG. 3, an auxiliary cylinder 5 arranged on the side of the cylinder 3, a main shaft 6 that moves linearly within the auxiliary cylinder 5, a crank joint 7 that connects the main shaft 6 and the top lid 4 and converts the linear motion of the main shaft 6 into a rotational motion of the top lid 4, a cam 8 that is arranged coaxially with the rotation axis of the crank mechanism 2 and rotates in synchronization with the rotational motion of the crank mechanism 2, and a control mechanism 9 that controls the linear motion of the main shaft 6 by the cam 8.

[0015] As shown in Fig. 1, the crank mechanism 2 includes a piston portion 13 that reciprocates inside the cylinder 3, a crank portion 14 that converts the reciprocating motion of the piston portion 13 into rotational motion, and a crankshaft 15 that serves as the rotation axis of the crank portion 14. The piston portion 13 is columnar, and a permanent magnet 11c is provided on one end surface that faces the upper cover. The crank portion 14 is connected to the piston portion 13, and performs rotational motion by converting the reciprocating motion of the piston portion 13 into rotational motion around the crankshaft 15 as an axis. The crankshaft 15 extends to the outside of the cylinder 3, and a cam 8, which will be described later, is connected to one end portion that is arranged outside the cylinder 3.

[0016] The auxiliary cylinder 5 is provided alongside the cylinder 3 and has a cylindrical shape extending in the vertical direction. A main shaft 6 is disposed inside the auxiliary cylinder 5.

[0017] The crank joint 7 includes a rod 17 connected to the top surface of the top lid, and a connecting part 18 that is rotatably disposed on the outer circumferential surface of the rod 17 and connects to one end of the main shaft 6. The reciprocating motion of the main shaft 6 is converted into a circular motion that opens and closes the top lid 4 by the connecting part 18.

[0018] The control mechanism 9 includes a cam 8, an electromagnet 10 provided on the auxiliary cylinder 5 and whose polarity is switched by the cam 8, a permanent magnet 11a provided on the main shaft 6 and arranged coaxially with the main shaft 6 and facing the electromagnet 10, and a microswitch mechanism 12 that switches the polarity of the electromagnet 10 by the cam 8.

[0019] The cam 8 is disk-shaped and has a protrusion 19 protruding from a portion of its circumferential surface, and the center of the disk is connected to the crankshaft 15. As a result, the cam 8 is disposed coaxially with the rotation axis of the crank mechanism 2, and rotates in synchronization with the rotation mechanism of the crank mechanism 2. The protrusion 19 actuates a microswitch mechanism 12 of the control mechanism 9, which will be described later.

[0020] 3, the microswitch mechanism 12 includes a power supply unit 20 that constantly supplies current to the electromagnet 10, a first supply path 21 that supplies current from the power supply unit 20 so that the electromagnet 10 has an N pole, a second supply path 22 that supplies current from the power supply unit 20 so that the electromagnet 10 has an S pole, and a switch unit 23 that switches between the first supply path 21 and the second supply path 22 by a pressing action of the protrusion 19 of the cam 8. When the protrusion 19 of the cam 8 is not pressing the protrusion 19, the current flows through the first supply path 21, and the electromagnet 10 and the permanent magnet 11a are set to have repulsive magnetism. When the cam 8 presses the switch unit 23 to switch from the first supply path 21 to the second supply path 22, the polarity of the electromagnet 10 is reversed, and the electromagnet 10 and the permanent magnet 11a attract each other. As a result, when the electromagnet 10 and the permanent magnet 11a attract each other, the main shaft 6 on which the electromagnet 10 is mounted moves vertically downward to close the top lid 4. When the cam 8 is not pressing the switch mechanism, the electromagnet 10 and the permanent magnet 11a repel each other, and the repulsive force causes the main shaft to move vertically upward and the top lid 4 opens.

[0021] The operation of the piston engine 1 of the first embodiment having the above-mentioned configuration will be described below with reference to FIGS. 1, 2, and 3.

[0022] When the piston engine 1 of the first embodiment is not in operation, the upper cover 4 does not cover the opening 3a of the cylinder 3, and the opening 3a is in an open state.

[0023] In this state, when the cam 8 is rotated and the switch portion 23 is pressed, the path through which the direct current supplied to the electromagnet 10 flows changes from the first supply path 21 to the second supply path 22, the polarity is reversed, the electromagnet 10 and the permanent magnet 11a become opposite poles and attract each other, the top lid 4 closes, and the opening 3a of the cylinder 3 is closed.

[0024] Since the permanent magnet 11b provided on the top lid 4 and the permanent magnet 11c provided on the piston portion 13 have the same polarity, the piston portion 13 moves downward due to repulsive force. When the piston portion 13 moves downward, the crank portion 14 rotates, and the cam 8 connected to the crankshaft 15 coaxial with the crank portion 14 also rotates. As a result, the cam 8 moves from the position where it presses the switch portion 23, so that the path through which the direct current supplied to the electromagnet 10 flows changes from the second supply path 22 to the first supply path 21, the polarity is reversed, and the electromagnet 10 and the permanent magnet 11a have the same polarity and repel each other, so that the top lid 4 opens and the cylinder 3 is opened.

[0025] Here, the cam 8 connected to the crankshaft 15 coaxial with the crank portion 14 also rotates due to the inertial force acting on the crank portion 14. Therefore, the above-mentioned operation is continuously repeated.

[0026] The piston engine 1 in the first embodiment having the above-mentioned configuration is a highly efficient engine that does not involve combustion, is quiet, does not emit CO2, and produces maximum output with minimum input. In addition, it has a simple structure and does not require complex control, so it can be easily implemented with existing technology.

[0027] <Second embodiment>

[0028] A piston engine 100 in the second embodiment will be described below with reference to Fig. 4. Note that the same parts as those in the first embodiment are given the same reference numerals and the description thereof will be omitted.

[0029] The piston engine 100 of the second embodiment differs from the first embodiment in the configuration of the control mechanism 9. The control mechanism 30 of the second embodiment includes a cam 8, a flow passage 32 provided in the auxiliary cylinder 5 and switching the flow direction of the fluid flowing through the auxiliary cylinder 5 by the cam 8, and a high-pressure fluid valve 35 that switches the flow passage 32 by the cam 8.

[0030] The flow path 32 includes a storage section (not shown) that stores the fluid, a supply path 31 through which the fluid flows out from the storage section, a first flow path 33 that branches off from the supply path 31 and causes the fluid to flow from bottom to top within the auxiliary cylinder 5, and a second flow path 34 that causes the fluid to flow from top to bottom within the auxiliary cylinder 5. A high-pressure fluid valve 35 is disposed at the branching point where the first flow path 33 and the second flow path 34 branch off, and the first flow path 33 is switched to the second flow path 34 by the action of the cam 8 pressing the high-pressure fluid valve 35.

[0031] The operation of the piston engine 100 of the second embodiment having the above-mentioned configuration will be described below with reference to FIG.

[0032] When the piston engine 100 of the second embodiment is not in operation, the upper cover 4 does not cover the opening 3a of the cylinder 3, and the opening 3a is in an open state.

[0033] In this state, when the cam 8 is rotated, the high-pressure fluid valve 35 switches the fluid flow direction from the first flow path 33 to the second flow path 34, and the main shaft moves downward, closing the top lid 4 and closing the opening 3a of the cylinder 3.

[0034] Since the permanent magnet 11b provided on the top lid 4 and the permanent magnet 11c provided on the piston portion 13 have the same polarity, the piston portion 13 moves downward due to repulsive force. The downward movement of the piston portion 13 rotates the crank portion 14, and the cam 8 connected to the crankshaft 15 coaxial with the crank portion 14 also rotates. As a result, the cam 8 moves from the position where it presses the high-pressure fluid valve 35, so the fluid flow direction changes from the second flow path 34 to the first flow path 33, and the main shaft moves upward, so that the top lid 4 opens and the cylinder 3 becomes open.

[0035] Here, the cam 8 connected to the crankshaft 15 coaxial with the crank portion 14 also rotates due to the inertial force acting on the crank portion 14. Therefore, the above-mentioned operation is continuously repeated.

[0036] As an example of the second embodiment engine, in order to improve the time discrepancy between power generation and electricity generation in a home solar power generation facility, when electricity is generated during the day, the electricity is used to turn a compressor to create high-pressure air and store it in a pressure vessel, and when the electricity is used, the high-pressure air is used to operate the engine to generate electricity, which is also effective as an emergency power source to be used as electricity, and it can be operated for a long time without the need to be replaced every few years like a storage battery.

[0037] In the first and second embodiments, too, experiments have shown that if neodymium magnets with a diameter of 12 mm and a thickness of 2 mm are used for the permanent magnet 11b provided on the top lid 4 and the permanent magnet 11c provided on the piston portion 13, and the opening angle of the top lid 4 is set to 60 degrees or more, the interaction between the permanent magnet 11b provided on the top lid 4 and the permanent magnet 11c provided on the piston portion 13 is reduced, allowing the piston portion 13 to rise smoothly.
