BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prime mover that converts energy into various forms and works by utilizing energy existing in various forms in nature.

[0002]

2. Description of the Related Art With the development of science and technology, various prime movers have been developed and are widely used in all fields. Among them, the rotary engine as a new principle that breaks the conventional concept is Japanese Patent Application No. 3-0237277 and Japanese Patent Application No. 3-35.
There is 6007.

[0003]

However, in the fields of pumps and motors other than rotary engines, inefficiency and reduction in size and weight have not progressed, and it has been very inconvenient to use the prime mover.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to solve such inconvenience by improving Japanese Patent Application No. 3-0237277 to provide a prime mover which is small in size and light in weight and efficient.

That is, when a square rotating body in which the length of the piston rod from the center of the rotating shaft and the length of the rotary piston are 1: 2 is rotated around the rotating shaft, both ends of the rotary piston are connected. In a casing engine having a curved line of a locus delineated on its inner peripheral surface, a rotary body is provided, and a plurality of ventilation holes are formed at appropriate positions in the casing cylinder. The piston rod is connected to the center of the corresponding rotary piston to enable rotation of the rotating body, and the support pins are projectingly fitted to the center of both ends of one rotary piston and both ends of both ends of the other rotary piston to form a connecting pin. Connect the fitting parts with to make a deformable square rotating body, and arbitrarily connect it to the line connecting the connecting pins to the outer circumference of the support part of each rotary piston. A long groove with an appropriate width is drilled along the length in the direction of the degree, and the plate-like seal with an appropriate width is attached to the long groove so that it can move up and down so that it is always in contact with the inner peripheral surface of the casing cylinder with an elastic body. In addition, the end seals are provided on both end faces of the seal so as to be in contact with the inner peripheral surface and the inner side surface so that the rotating body is kept airtight during rotation.

[0006]

When the rotary shaft rotates, the rotary piston is moved via the piston rod to rotate the rotary body in the casing cylinder while deforming it from a square to a parallelogram and then to a square. While the rotating body makes one rotation, the rotary piston performs one stroke of intake, compression, and exhaust twice, so that the rotating body has four strokes, that is, eight strokes. The airtightness in that case is also kept by the elastic body so that the seal is always in contact with the inner peripheral surface of the casing cylinder and the terminal seal is kept in contact with the inner surface, and even if the rotary body is deformed and the rotary piston swings, each seal will be Accordingly, even if it swings in an arbitrary direction, they do not separate from each other, and the seal end faces are overlapped with each other, so that airtightness is maintained.

Is formed. Reference numeral 13 is a casing cylinder having a curved inner surface 13a of the locus drawn when the ends of the rotary pistons 4 and 10 rotate about the rotating shaft 2, and the ventilation holes 14a, 14b, 14c, 1 are provided at corresponding four appropriate positions.
4d is drilled. Reference numeral 15 denotes a plate-like seal which is embedded in the long groove 6a via an elastic body 16 so as to be vertically movable, and is closely attached to the inner peripheral surface 13a of the casing cylinder 13 during rotation to maintain airtightness. 17 is a plate-shaped seal,
It is embedded in the long groove 11a via an elastic body 16 so as to be movable up and down, and is in close contact with the inner peripheral surface 13a of the casing cylinder 13 to maintain airtightness. 18 is a terminal seal,

Airtightness is maintained by closely adhering to 3a and the inner side surface 13b.

Next, the operation will be described. When the driving device operates and is transmitted to the rotary shaft 2, the piston rod 3 rotates to move the rotary piston 4 via the piston pin 9, and also the rotary piston 10 via the connecting pin 12 to move the rotary body 1 to the casing cylinder 13 Inside, rotate from the state of a square to a parallelogram and then transform it into a square. And while the rotating body 1 makes 1/4 rotation, 2/4 rotation, 3/4 rotation, and 1 rotation, the ventilation holes 14a, 14
rotary pistons 4, 1 by b, 14c, 14d
Table 1 shows whether the space formed by the surface of No. 0 and the casing cylinder 13 is in the intake state or the exhaust state, based on FIGS. 7, 8 and 9.

[0010]

[Table 1]

In this way, since the rotating body 1 is rotated four times at two places at the same time during one rotation, the intake, compression and exhaust of eight strokes are performed as a whole. And airtight seal 15,1
7 is kept up and down by the elastic body 16 and the terminal seal 18, and the seals 15, 17 are maintained even if the angle formed by the rotary pistons 4, 10 is other than 45 ° (FIG. 5 shows the case of 90 °). 6 are overlapped with each other (FIG. 6 shows a case where the angles of the rotary pistons 4 and 10 are smaller than 90 °, and when they are large, the seals 15 and 17 are reversed), and airtightness is maintained.

[0012]

As described above, the present invention is suitable for quiet and high speed operation with less vibration even with one rotor and without balancing, omitting the auxiliary piston rod that oscillates, and the connecting portion of the rotating body swings during rotation. By eliminating the occurrence of airtight leaks by superposing seals and terminal seals, and making it possible to reliably maintain airtightness, the structure is simple and compact and lightweight, and even if it is small, the discharge amount can be large and it is economical. It is a very excellent invention in industry because it has many features such as it can be used for small rotary engine, compressor (pump) and motor, and its application range is wide.
