[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic piston engine using a permanent magnet.

[0002]

2. Description of the Related Art Conventionally, an electric motor is well known as a drive engine using an electromagnet and a permanent magnet, but a magnetic piston engine capable of continuously driving a piston using only a permanent magnet to take out a rotational drive force is now available. Not out.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a magnetic piston engine capable of continuously driving a piston by using only permanent magnets to take out rotational driving force.

[0004]

In order to achieve the above-mentioned object, the present invention mounts a piston in a cylinder so that it can move up and down, and one or a plurality of magnetic poles are directed outward on the outside of the piston. A first permanent magnet is attached, and the other end of the connecting rod, one end of which is pivotally attached to the piston, is attached to a rotary shaft that is rotatably provided in the lower portion of the cylinder. The first permanent body is attached to the side wall of the cylinder by urging the cylinder in one direction and sliding in a direction orthogonal to the piston. A second permanent magnet is attached so that only magnetic poles different from the magnet are directed to the piston side, and the sliding body is moved via a cam mechanism driven by the rotary shaft via a driving force transmission means, and the second permanent magnet is moved. of The permanent magnet, by advancing and retracting toward said first permanent magnet is obtained by so as to vertically operate continuously performed to the piston.

In this case, according to the present invention, the sliding body can be installed on the piston in a plurality of directions, and the first permanent magnet attached to the piston is formed into a flat plate shape or a convex surface shape.
The shape of the second permanent magnet attached to the sliding body can be a flat plate shape or a concave shape corresponding to the shape of the first permanent magnet.

Further, according to the present invention, convex portions are provided on the surfaces of the first permanent magnet and the second permanent magnet, respectively, and the magnetic force of each convex portion is strengthened for use, or the sliding member is used as a crank mechanism instead of a cam mechanism. You can slide it with.

[0007]

When the piston is located at the top dead center of the cylinder as shown in FIG. 1, the sliding member is located closest to the piston side due to the action of the cam mechanism. The N pole is magnetically attracted to, for example, the S pole of the second permanent magnet on the sliding body side, and descends to rotate the flywheel through the connecting rod. When the piston is magnetically attracted to the stroke of about two-thirds, the pressing force on the sliding body by the cam mechanism is released, and the sliding body retreats from the piston side due to the elastic force of the compression spring, and the separation distance is the piston. Reaches the maximum at bottom dead center in the cylinder. Therefore, since the magnetic attraction force to the piston becomes extremely weak, the piston turns upward from the bottom dead center and reaches the top dead center via the connecting rod due to the inertial rotational force of the flywheel. When the piston reaches the top dead center, the sliding body slides toward the piston side again due to the action of the cam from the position before the top dead center, so that the magnetic attraction to the first permanent magnet by the second permanent magnet starts and the piston descends. To do. In this way one cycle is completed,
After that, the above-mentioned operation is automatically and continuously repeated. The driving force that gives the piston the first ascending / descending movement is externally applied by human power or a cell motor as in a normal internal combustion engine.

A connecting rod 19 is axially attached to the piston 3 at one end thereof, and the other end of the connecting rod 19 has an outer periphery of a flywheel 21 having a weight 21a eccentrically attached to the rotary shaft 20. The axis of rotation is different from that of the rotary shaft, and the shaft is mounted nearby. Although not shown, a parent pulley is attached to the rotary shaft 20.

Incidentally, it is optional to attach a plurality of pistons and connecting rods to the rotary shaft by a crank mechanism corresponding to two cylinders, four cylinders, etc. of the internal combustion engine.

FIGS. 3 to 4 show the relationship of the clearance between the first permanent magnet mounted on the piston side and the second permanent magnet mounted on the sliding body side as the piston moves up and down in the cylinder. By devising the shape of the cam, when the magnetic force of the piston is attracted, that is, when the piston is descended, the clearance is small until the attraction descending stroke of about two-thirds of the top dead center, but thereafter, it rapidly increases until bottom dead center. The clearance is expanded so that the magnetic attraction force is weakened, and the expansion width of this clearance is maintained up to about two-thirds of the ascending stroke, after which the clearance is designed to be sandwiched rapidly.

FIG. 5 is an explanatory view of a permanent magnet suitable for constructing a magnetic piston engine, in which a magnetic member 31 magnetically attracted to the permanent magnet 30 is provided with a convex portion 31a, and the magnetic member 31 is transferred to another magnet. When brought close to each other, the magnetic force line passing through the magnetic body 31 is
Just like the flow of electricity, it tries to flow at the shortest distance to the opposing magnetic substance, and as shown by the arrow, this convex portion 30
The magnetic force of the convex portion 31a has a property of becoming extremely strong as compared with other places.

Utilizing this property, when each magnetic body magnetically attracted to each permanent magnet is provided with a convex portion so as to be opposed to each other as in the above-described embodiment, it is possible to place the convex surface opposite to a normal magnetic body. A large imbalance of magnetic lines of force is generated between the respective permanent magnets, and the operation becomes easier.

Even if such a known crank mechanism is used, the sliding body can be slid in synchronization with the rotating shaft rotated through the flywheel.

[0018]

Since the present invention is constructed as described above,
Only the first drive is done manually or by a cell motor, but after that, the permanent magnet alone causes the piston to continuously move up and down, and this is transmitted to the rotary shaft via the connecting rod and flywheel,
It can be taken out as a rotational force.
