Abstract

Provided is a rotary engine with less mechanical loss caused by noise, vibration and friction and improved thermal efficiency due to the airtightness. A rotor(4) with a vane(3) is fixed to a center output axis(2) of a housing(1). On the circumferential surface of the rotor, a roll(7) with a compressed air room(6) and a recess(5) are press-welded and rotate oppositely. Short shafts integrally protruded on a side housing are inserted in the compressed air room formed in the center of the roll and support the roll to rotate. A fuel nozzle and an ignition plug(9) are set up on the short shafts. A partition(12) in which a spring is intervened in an axis is set up on a concave inner wall(10) of the housing bottom. An air intake(13) and an exhaust hole(14) are punched on the right and left of the partition. A U-shaped elastic seal(16) is inserted in the vane close to the housing and side housing. A seal ring(16') of spring washer type is inserted in a circular groove formed on the periphery of the rotor.

Conventional reciprocating internal combustion engines have a large torque change and thus have a high impact, signal, and noise, as well as large inertia resistance due to reciprocation of the crank piston, resulting in a significant drop in mechanical efficiency and a rotary engine, a Wankel engine. Since the rotary rotor is triangular, the airtight and lubrication cooling between the apex seal and the housing is difficult, and the difference in thermal expansion and thermal deformation due to the temperature difference between the housing parts is difficult. Due to the difficulty in manufacturing, housing, rotor, etc., there was a defect that the production cost increased.

Since these drawbacks come from the inherent drawbacks of triangular rotors, there is little room for improvement.

The present invention solves the deficiencies of the conventional engine as described above to meet the essential requirements as an internal combustion engine, such as airtightness, lubrication, cooling, noise, vibration, manufacturing difficulty, thermal efficiency in the operating room to reduce the weight and volume per horsepower and It is designed for the purpose of inexpensive, high fuel consumption, intermittent combustion cycle engine.

In order to achieve the above object, it eliminates inertia resistance which is a defect of reciprocating internal combustion engine, improves mechanical loss due to noise, vibration and friction by smooth rotational movement without changing torque, and improves weight and volume per horsepower as a simple structure. The company develops a fuel-efficient rotary engine with reduced airtightness, durability and cost of production.

And the roll 7 formed with the compressed air chamber 6 at the center thereof.

In the compressed air chamber 6 formed at the center of the roll 7 so as to be rotated in the opposite direction and formed in the same direction in the side housings 15 and 15 '. 17 ') is rotated to rotate the rolls 7, and both fuel shafts 8 and ignition plugs 9 are installed on both short shafts 17 and 17' and the lower housing ( 1) An inner wall recessed surface 10 is provided with a partition 12 having a spring 11 interposed on a shaft 11 ', and an intake hole 13 and an exhaust hole on both left and right sides thereof. 14, and the wings 3 are housed with elastic U-shaped seals 16 close to the housing 1 and the side housings 15 and 15 '. And a spring washer-type seal ring (16 ') is inserted into a circular groove cut around the rotor (4).

In the drawings, reference numerals 17 and 17 'are short axis, 18 is a coolant chamber, 19 is a wheel 20, and a seal ring is indicated.

The operation of the present invention configured as described above is as follows.

When the rotor 4 rotates in the direction of the arrow, one side of the vane 3 protruding into the same sucks fresh air from the intake hole 13, and the other side compresses the previously sucked air. (4) A small compressed air chamber in which a large compressed air is formed at the center of the roll 7 by the time the blade 3 is engaged with the recess 5 of the roll 7 which is close to the upper surface and rotates in the opposite direction. In the compressed air chamber (6) in the compressed air chamber (6) when the blade (3) is pushed out and the wing (3) moves to the right and moves away from the recess (5) of the roll (7) as shown in FIG. At the same time fuel is injected, it is ignited by the spark plug (9) to explode.

In this manner, the combustion gas exploded once per revolution of the rotor 4 rapidly expands and exerts high pressure on the blade 3 to smoothly rotate the center output shaft 2, and the expanded exhaust gas is applied to the lower housing 1. It is rapidly discharged to the snow exhaust hole 14.

As described above, when the wing 3 of the rotor 4 rotates close to the inner wall of the housing 1 and passes while pushing the lower partition 12, the spring 11 intervening in the shaft 11 'is moved. Due to its elasticity, it rests on the concave surface 10 formed on the inner wall of the lower part of the housing 1 for a while, and then returns to its original shape again at the moment when the wing 3 passes, and closes to the rotor 4 so that A part is blocked from moving toward the intake hole 13 and continues to guide the exhaust hole 14 to be discharged.

And a U was inserted into the rotor blade 3 and a spring washer-shaped seal ring 16 'fitted in a circular groove cut around the rotor 4; Since the seal 16 is tightly pressed against the inner wall of the housing 1 and the inner wall of the side housings 15 and 15 ′, leakage of the combustion gas is suppressed, thereby improving thermal efficiency.

In the practice of the present invention, in the case where the diameter of the roll 7 is 1/2 of the rotor 4, when the blades 3 are expanded to two, the output of the rotor 7 explodes twice in one revolution of the rotor 4. Improved by 2x

)이 확보되므로 열효율 향상으로 연비가 높아진다.In the present invention, since both the rotor and the roll in the housing 1 are rotational movements, the machine loss is small, there is little noise and vibration, and the vanes 3 of the rotor 4 are provided. The enclosed U-shaped seal 16 and seal ring 16 ′ are in close contact with the inner walls of the housing 1 and the side housing 15 to be hermetically sealed.

), The fuel efficiency is increased by improving the thermal efficiency.

In addition, since the weight and volume of the engine are small, the weight per horsepower is small and the manufacturing is easy, thus reducing the production cost.
