An engine of an automobile or the like using a so-called vane type rotary mechanism in which a series of partition wall plates described above are pressed against a cam ring and rotated to change the volume is used. Under conditions where completely opposing functions of securing a seal and smooth sliding are required in order to obtain rotational force by utilizing the effect of the explosion without loss, it is practically impossible to satisfy both requirements while satisfying both requirements. It is possible.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a vane type rotary capable of satisfying the contradictory requirements of seal and sliding.
It is an object of the present invention to provide an engine for an automobile or the like.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, a rotary engine for a car or the like using a positive displacement piston mechanism having a rotary piston structure according to the present invention is provided with a ring housing having a bearing housing. A small rotor integrated with the main shaft is eccentrically arranged in a large rotor composed of a large rotor and a pair of slide grooves having predetermined directions and inclinations at equal intervals at the opposite parts of the large rotor and the small rotor.

[0009]

The present applicant has filed Japanese Patent Application No. 314885/1997, and a so-called vane type rotary mechanism in a conventional rotary piston structure pushes the vane to the cam ring to gradually increase the volume. The fate of the structure, which must partition the changing chamber, is to wear the vane tip, make it difficult to properly apply the vane pressing mechanism, and rotate and fold the seal to secure it. Despite the difficulties of simultaneously achieving the contradictory functions of ensuring airtightness and smooth operation, the above problems are currently solved only by tactical devices, and their effects are limited. In view of the above, a positive displacement piston mechanism having a rotary piston structure has been proposed which solves all of the above-mentioned problems by strategically modifying the vane type rotary mechanism.

That is, a small rotor eccentric to a large rotor composed of an annular cylinder holding a bearing in a bearing housing and integrated with a main shaft.
A pair of slide grooves having predetermined directions and inclinations are engraved at the equally dividing points of the large rotor and the small rotor, and bent vanes having a predetermined bending angle are formed in the slide grooves. Are inserted and inserted in a cross-linking manner, and suction / discharge ports are provided at predetermined portions of the side housing. This will be described below with reference to FIGS.

A small rotor 32 integral with the main shaft 31 is eccentrically disposed in a large rotor 33 formed of a ring-shaped cylinder. The large rotor 33 is supported by a bearing housing 34. Naturally, the small rotor 32 described above and the large rotor 3 described above
3 is a side housing 35 assembled with bolts 36,.
It is narrowly mounted between 35 '. A pair of sliding grooves 37,..., 38,... Having a predetermined direction and inclination are formed in opposite portions of the small rotor 32 and the large rotor 33, and are bent between the sliding grooves 38, 38 by a predetermined amount. Corner bending vane 39,
... are fitted and inserted in a bridged manner.

Thus, there is provided a unique rotation mechanism in which the large rotor 33 is accompanied by the bent vane 39 which always seeks the balance bridge point for the rotation of the small rotor 32. The rotating mechanism is formed by bending vanes 39 to define compartments 40,.
Which change their volume as they rotate. During this time, the bending vanes 39 are merely slide grooves 37, 38.
It only slides inside.

Here, a mechanism having the same function, which is completely different from the conventional vane type rotary mechanism, in which the tip of the cantilever is slid while pressing the tip of the cantilever against the fixed cam ring to achieve the volume change. Provided. Therefore, as shown in FIGS. 7 to 9, if a predetermined portion of the side housing 35, 35 ′ is set according to the application, for example, as the suction and discharge ports 41, 42, it can be operated as a positive displacement piston mechanism having a rotary piston structure. Is possible.

For example, when the main shaft 31 of the machine and the small rotor 32 fixed to the main shaft 31 rotate counterclockwise, the bending vane 39 becomes a medium, and the large rotor 33 rotates counterclockwise. Are also rotated counterclockwise. When each compartment 40 rotates counterclockwise, the volume of each compartment 40 increases and decreases once. When the volume of the compartment 40 increases, fluid is sucked into the compartment 40 from the suction port 41, and when the volume of the compartment 40 decreases, the fluid in the compartment 40 is discharged from the outlet 42 to the outside of the compartment 40. This will act as a pump.

The amount of fluid discharged from the pump can be adjusted by changing the amount of eccentricity of the large and small rotors 33 and 32.
The use for the bent vane motor is performed as follows. The high-pressure fluid from the high-pressure fluid generating device is combined with a device that generates the high-pressure fluid while using the fluid discharge port 42 as the fluid inlet, the fluid suction port 41 as the fluid discharge port, and It is constantly supplied into the compartment 40 from the inflow port (42). The fluid entering the compartment 40 exerts a pressure on the bent vane 39. The pressure on the bent vane 39 causes the main shaft 31 to rotate clockwise, and the compartment 40 also rotates clockwise. When the compartment 40 rotates and moves to the position of the outlet (41), the fluid in the compartment 40 flows out of the compartment 40 from the outlet (41).

Accordingly, the motor operates as a fluid pressure rotating motor. Further, application to a heat engine is performed as follows. In the bent vane motor, an inflow hole of a small hole into which the hot gas flows is installed instead of the fluid inlet (42) (not shown). The position of the inlet hole (42) is determined when the compartment 40 of the motor rotates clockwise.
It is set to a position at which the volume of the compartment 40 starts to increase. On the other hand, the outlet (41) for the fluid of the bent vane motor is used as an exhaust port for exhausting hot gas.

An apparatus (not shown) for generating a high-temperature and high-pressure gas is combined with the hot gas bending vane motor. This operation is as follows. One of the compartments 40 at the position of the hot gas inflow hole (41) is selected from the n compartments 40,... Of the hot gas bending vane motor.
The operation of 0 will be described.

First, the high-temperature and high-pressure gas from the high-temperature and high-pressure gas generator is constantly introduced into the compartment 40 at the position of the hot gas inlet (42) from the hot gas inlet (42). . The high-temperature and high-pressure gas flowing into the compartment 40 exerts pressure on a pair of bent vanes 39 forming the compartment 40. At this time, the two bent vanes 39, 39 are subjected to pressures for pushing in opposite directions. However, since there is a difference between the areas of the two bending vanes 39, 39 subjected to pressure,
A difference occurs in the torque with respect to the main shaft 31. This difference in torque causes the main shaft 31 to rotate clockwise. The compartment 40 also rotates clockwise.

As the chamber rotates, the volume of the compartment 40 increases, and high-temperature and high-pressure gas flows into the compartment 40. Since the pressure of the high-temperature and high-pressure gas continues to act on the bending vane 39, the main shaft 31 continues to rotate, and
0 also keeps rotating. Next, when the compartment 40 rotates and passes through the hot gas inflow hole (41), the inflow of the high-temperature and high-pressure gas into the compartment 40 stops. Subsequently, when the compartment 40 rotates, the volume of the compartment 40 increases, and the compartment 4
The high-temperature, high-pressure gas within 0 expands adiabatically. Since the pressure of this adiabatic expansion continues to act on the bending vane 39, the main shaft 3
1 continues to rotate, and the compartment 40 also continues to rotate.

Next, when the compartment 40 rotates and moves to the position of the hot gas exhaust port (41), the hot gas in the compartment 40 is discharged from the hot gas exhaust port (41) to the outside of the compartment 40. I do.
The above operation is similarly established when the other compartment 40 rotates clockwise and comes to the position of the hot gas inflow hole (42), so that the rotational force to the main shaft 31 continues one after another. Will work. Therefore, the mechanical device operates as a heat engine.

In the vane type rotary mechanism having the novel structure described above, the bent vane 3 having the compartment structure is used when the volume is changed.
9 requires only sliding of the bridge piers in the slide grooves 37 and 38, so that the airtightness is remarkably high because the driving is smooth and a planar contact pressure is involved. Can be expected to improve, and solve the long-standing issues already mentioned. Thus, in the engine of the present invention in which the intake / exhaust ports 41 and 42 are controlled to be opened and closed, the compartment 40 is formed in the same manner as the reciprocating engine room under the enjoyment of the effects described above. Suction, compression, combustion, and exhaust can be operated by two rotations of the main shaft 31 at 720 ° (two cycles).

That is, an engine is provided which enables the number of combustions to be equal to the number of compartments 40 by two rotations of the main shaft 31.
