The present invention relates to a rotary engine, and more particularly, to uniformly distribute the compressive force transmitted to the vane valve so as to slide smoothly along the rotor even at high pressure, as well as airtight to maintain the airtightness with the rotor in the vane valve By resilient means to extend the life of the rotary engine, while reducing the pulsation caused by the pressure difference between the suction chamber and the compression chamber, while improving the shape of the rotor to suck a large amount of air at the same time to exhibit a high compression force The present invention relates to a rotary engine that provides high power as well as high speed rotation.

Conventional reciprocating engines have a small size relative to the total engine volume that generates mechanical energy due to complex mechanical construction, and also has a limitation in rotational speed. In addition, the mechanical loss is inevitable in the process of changing the reciprocating motion to rotational motion, there was a problem that vibration occurs. As a way of overcoming this, a rotary engine using an inner etrooid curve housing and an eccentric shaft has been used.

Since the eccentric shaft and the rotor contact with each other do not always correspond to the direction in which the rotor is subjected to inflation pressure, the seal and the housing attached to the rotor are subjected to high pressure, and the durability is significantly lower than that of the reciprocating engine. High precision is required for the processing of the rotating body and the housing is not widely used. In addition, the capacity of the turbocharger and intercooler to compensate for the thermodynamic losses consumed in the exhaust process is limited to the extent that the exhaust process is not disturbed.

One known method for overcoming the above problem is described in US Pat. No. 6,129,067 filed by Thomas Lily.

However, this type of engine has the disadvantage that the volume and size of the engine is too large compared to the exploding internal space, and can not be applied to the engine of the compression ignition method.

Further, in the related art, a rotary engine (Japanese Patent Laid-Open No. 10-311224) as shown in FIG. 1 has been developed. In the conventional rotary engine configured as described above, the rotor 19 is raised in one direction in a circle shape. Since the hydraulic pressure unit 26 is formed, the hydraulic pressure unit 26 has a very short contact time with the suction rotating body 23, so the compression force and the amount of compression are very small. Therefore, the hydraulic pressure unit 26 cannot be used where a high power engine is required. There was this.

Therefore, the present invention has been researched and developed in consideration of the above problems, uniformly distributes the compressive force transmitted to the vane valve to smoothly slide along the rotor at high pressure, as well as airtightness with the rotor in the vane valve By providing a resilient means to maintain the life of the rotary engine to extend the life of the rotary engine and to reduce the pulsation caused by the pressure difference between the suction chamber and the compression chamber, while improving the shape of the rotor to suck a large amount of air at the same time high pressure Its purpose is to provide a rotary engine that provides high power as well as high-speed rotation to be realized.

After forming a vane groove on one inner side of the main housing, a vane valve sliding along the outer circumference of the rotor is installed in the vane groove so as to be rotated by a predetermined angle by the hinge, but the vane valve is concentric with the vane shaft. Compression surface is formed so that the high pressure fluid pressure is uniformly distributed, and compressive force transmitted to the compression surface is transmitted to the vane shaft part, and the airtight seal member has a seal member at the compression surface end of the vane valve in contact with the rotor. While installing means to maximize the airtightness of the rotor and the vane valve, while forming a ridge on one side of the rotor so that the compression surface portion is formed on one side of the ridge, the suction surface portion is formed on the other side of the ridge, also it extends to the compression time of the rotor to form a more or less smooth surface than the suction surface to be as close to concentric circles and at the same time of the compression chamber It is characterized in that it is possible to greatly increase the compression force according to the minimization.

In addition, the present invention forms one or two seal grooves with locking grooves inwardly at the ridge apex of the rotor, and then elastically installs an airfax seal together with an elastic member in the seal grooves, and both edges of the rotor. Form one or two side seal grooves along the side seal groove, characterized in that the side seal is elastically installed along with the elastic member.

The present invention is also provided with an airtight means at the compression surface end of the vane valve in contact with the rotor, the airtight means springs the vane seal member having a locking jaw to form a vane seal groove having a locking groove at the end of the vane valve. In addition to the elastic installation, the side seal groove is connected to the vane seal groove along the both sides of the compression surface of the vane valve characterized in that the side seal is elastically installed with the spring.

In addition, the present invention is formed on each side of the vane seal groove of the vane valve has a fixed seal groove having a shape similar to the ' Neun ' shape of the cross-section of the Hangul , respectively, and then stably fix the vane seal member installed in the vane seal groove in the fixed seal groove After inserting the fixed seal member having a shape similar to the 'Neeeun' shape of the Hangul cross section so as to be able to make it, and formed a shaft seal groove to turn a part of the vane shaft in the fixed seal groove, characterized in that the shaft seal member with the spring do.
