Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the piston engine described in Patent Document 1, power is required to switch the direction of current flow to the electromagnet, and thus it cannot contribute to energy saving. In addition, since a control mechanism for switching the direction of current flow to the electromagnet is also required, there is a problem that the device becomes complicated.

[0006] In view of the above problems, the object of the present invention is to develop a highly efficient reciprocating engine that uses power supplementally, mainly relies on the force of a permanent magnet, has a simple structure, and does not perform complex control.

Means for Solving the Problems

[0007] The piston engine of the present invention comprises a cylinder with an open top and a crank mechanism inside, a top cover that opens and closes the opening of the cylinder and rotates with one end as a pivot, an auxiliary cylinder arranged to the side of the cylinder, a main shaft that moves linearly inside the auxiliary cylinder, a crank joint that connects the main shaft and the top cover and converts the linear motion of the main shaft into rotational motion of the top cover, and a control mechanism that is arranged coaxially with the rotation axis of the crank mechanism and rotates in synchronization with the rotational motion of the crank mechanism, and controls the linear motion of the main shaft by the cam, and is characterized in that permanent magnets of the same pole are arranged in the top cover and the crank mechanism, respectively.

[0008] With the above configuration, permanent magnets of the same polarity are positioned on the top cover and the crank mechanism, so the cylinder remains open. When the cam rotates from this state, the control mechanism controls the linear motion of the main shaft, causing the main shaft to move vertically downwards. This closes the opening of the cylinder with the top cover. Since permanent magnets of the same polarity are positioned on the top cover and the crank mechanism, the repulsive force of the magnets causes the crank mechanism to move vertically downwards and rotate. Then, the crank mechanism rises vertically upwards again, and the repulsive force of the magnets opens the top cover. At this time, the cam, which is positioned coaxially with the rotation axis of the crank mechanism, also rotates, so the control mechanism causes the main shaft to move vertically upwards again, and the above motion is repeated. This repeated motion allows the crank mechanism to rotate even without fuel, and a highly efficient piston engine can be realized with a simple structure and without complex control. [Effects of the Invention]

[0009] This invention provides a highly efficient piston engine that uses electricity only as a supplement, primarily relies on the force of permanent magnets, and has a simple structure without requiring complex control. [Brief explanation of the drawing]

[Figure 3] Control mechanism for a piston engine in the first embodiment (DC power supply type) [Figure 4] Control mechanism for a piston engine in a second embodiment (high-pressure fluid type) [Modes for carrying out the invention]

[0011] The piston engine of the present invention will be described in detail below with reference to the drawings. The embodiments described below are merely examples of the present invention, and the present invention is not limited to these embodiments.

[0012] <First Embodiment>

[0013] The piston engine 1 in the first embodiment will be described below with reference to Figures 1 to 4.

[0014] As shown in Figure 1, the piston engine 1 in the first embodiment includes a cylinder 3 with an open top and a crank mechanism 2 inside, a top cover 4 that opens and closes the opening 3a of the cylinder 3 and rotates with one end as a pivot, an auxiliary cylinder 5 arranged to the side of the cylinder 3 as shown in Figure 3, a main shaft 6 that moves linearly inside the auxiliary cylinder 5, a crank joint 7 that connects the main shaft 6 and the top cover 4 and converts the linear motion of the main shaft 6 into the rotational motion of the top cover 4, a cam 8 arranged coaxially with the rotation axis of the crank mechanism 2 and rotating 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 a rotational motion, and a crankshaft 15 that serves as the rotation axis of the crank portion 14. The piston portion 13 has a columnar shape, and a permanent magnet 11c is provided on one end surface facing the upper lid. The crank portion 14 is connected to the piston portion 13 and converts the reciprocating motion of the piston portion 13 into a rotational motion about the crankshaft 15 to perform a rotational motion. The crankshaft 15 extends to the outside of the cylinder 3, and a cam 8 described later is connected to one end portion disposed outside the cylinder 3.

[0016] The auxiliary cylinder 5 is provided adjacent to 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 body 17 connected to the upper surface of the upper lid, and a connecting portion 18 that is rotatably disposed on the outer peripheral surface of the rod body 17 and connects to one end portion of the main shaft 6. By the connecting portion 18, the reciprocating motion of the main shaft 6 is converted into a circular motion for opening and closing the upper lid 4.

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

[0019] The cam 8 has a disk shape and includes a protrusion 19 protruding from a part of its circumferential surface, and the center of the disk shape 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 operates the microswitch mechanism 12 of the control mechanism 9 described later.

[0020] As shown in Fig. 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 becomes the N pole, a second supply path 22 that supplies current from the power supply unit 20 so that the electromagnet 10 becomes the S pole, and a switch unit 23 that switches the first supply path 21 and the second supply path 22 by the pressing operation 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 magnetic properties. When the cam 8 presses the switch unit 23 and switches 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 are attracted to each other. As a result, when the electromagnet 10 and the permanent magnet 11a are attracted to each other, the main shaft 6 provided with the electromagnet 10 moves vertically downward and the upper lid 4 closes. When the cam 8 is not pressing the switch mechanism, the electromagnet 10 and the permanent magnet 11a repel each other, and the main shaft moves vertically upward by the repulsive force and the upper lid 4 opens.

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

[0022] ​​​​​​​​Since the permanent magnet 11b on the top cover 4 and the permanent magnet 11c on the piston section 13 are of the same polarity, the piston section 13 moves downward due to the repulsive force. As the piston section 13 moves downward, the crank section 14 rotates, and the cam 8 connected to the crankshaft 15, which is coaxial with the crank section 14, also rotates. As a result, the cam 8 moves away from the position where it presses the switch section 23, so the path through which the DC current supplied to the electromagnet 10 flows changes from the second supply path 22 to the first supply path 21, the polarity reverses, and the electromagnet 10 and the permanent magnet 11a become of the same polarity and repel each other, causing the top cover 4 to open and the cylinder 3 to open.

[0025] Here, the inertial force acting on the crank section 14 causes the cam 8, which is connected to the crankshaft 15 coaxial with the crank section 14, to rotate as well. As a result, the above-described operation is repeated continuously.

[0026] The piston engine 1 in the first embodiment, having the configuration described above, is a highly efficient engine that does not involve combustion, is quiet, emits no CO2, and delivers maximum output with minimum input. Furthermore, it has a simple structure and can be easily implemented using existing technologies without requiring complex control.

[0027] <Second Embodiment>

[0028] The piston engine 100 in the second embodiment will be described below with reference to Figure 4. Parts identical to those in the first embodiment are denoted by the same reference numerals, and their descriptions are omitted.

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

[0030] The flow path 32 comprises a fluid containment section (not shown) for containing fluid, a supply passage 31 from which fluid is discharged from the containment section, a first flow path 33 that branches off from the supply passage 31 and causes fluid to flow from bottom to top within the auxiliary cylinder 5, and a second flow path 34 that causes fluid to flow from top to bottom within the auxiliary cylinder 5. A high-pressure fluid valve 35 is positioned at the branching point where the first flow path 33 and the second flow path 34 branch off, and the flow switches from the first flow path 33 to the second flow path 34 when the cam 8 presses the high-pressure fluid valve 35.

[0031] The operation of the piston engine 100 of the second embodiment having the above-described configuration will be explained below with reference to Figure 4.

[0032] In the second embodiment, when the piston engine 100 is not operating, the top cover 4 does not block the opening 3a of the cylinder 3, and is in an open state.

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

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

[0035] Here, the inertial force acting on the crank section 14 causes the cam 8, which is connected to the crankshaft 15 coaxial with the crank section 14, to rotate as well. As a result, the above-described operation is repeated continuously.

[0036] As an example of the second embodiment of the engine, in order to improve the time discrepancy between power generation and electricity supply in a home solar power generation facility, during daytime power generation, the electricity is used to run a compressor to create high-pressure air, which is stored in a pressure vessel. When electricity is needed, the engine is operated with the high-pressure air to generate electricity, and this is also effective as an emergency power source that does not require replacement every few years like a storage battery, and can be operated for a long period of time.

[0037] In addition, experiments have shown that in both the first and second embodiments, when neo-shim magnets with a diameter of 12 mm and a thickness of 2 mm are used for the permanent magnet 11b provided on the top cover 4 and the permanent magnet 11c provided on the piston part 13, and when the opening angle of the top cover 4 is set to 60 degrees or more, the interaction between the permanent magnet 11b provided on the top cover 4 and the permanent magnet 11c provided on the piston part 13 is reduced, and the piston part 13 rises smoothly.
