A vane valve(8) in which a vent hole(7) is punched in the center moves up and down with the lower end loaded on the upper side of the rotor. An air chamber(9) and a combustion chamber(11) are formed on the left and right sides of the guide groove. Two side wall holes(10,10') connected with the guide groove is punched on the side wall. A fuel injection valve(12) and an ignition plug(13) are installed in the combustion chamber of the right side. An air intake(14) and an exhaust(15) are punched on the left and right sides of the bottom of the housing.

종래의 왕복동 내연기관(recipro cating engine)은 진동,소음,부피,무게가 클뿐만 아니라 크랭크 피스톤의 왕복운동에 따른 관성저항이 크며, 회전피스톤으로 된 반켈엔진(Wankel engine)은 그 회전 로우터가 삼각형으로 되어 있기 때문에 그 에이펙스시일(Apex seal)의 마모로 인한 연소가스의 리이크(leak)가 심하여 출력이 떨어지고, 제작성의 어려움으로 생산 원가가 상승하는 결점이 있었다.Conventional recipro cating engine has not only high vibration, noise, volume and weight, but also high inertia resistance due to the reciprocating motion of the crank piston.Wankel engine made of rotating piston has a rotating rotor of which triangle Since the leak of the combustion gas due to the wear of the apex seal is severe (leak), the output is lowered, the production cost was increased due to the difficulty of manufacturability.

이러한 결점은 삼각형 로우터의 본질적인 결함에서 오는 결점이기 때문에 앞으로도 개량 될 전망이 거의 없다.These drawbacks come from the inherent drawbacks of triangular rotors, so there is little prospect for future improvements.

본 발명은 이상과 같은 종래 엔진의 결점을 해결하여 작동실내의 기밀확보,윤활,냉각,소음,진동,내구성,제작의 난이성 등 내연기관으로서의 필수요건을 모두 감안하여 마력당 중량 및 부피를 작게하고, 저공해 고연비의 간헐 연소사이클의 저렴한 엔진을 목적으로 안출한 것이다.The present invention solves the deficiencies of the conventional engine as described above to reduce the weight and volume per horsepower in consideration of all the essential requirements as an internal combustion engine, such as airtightness, lubrication, cooling, noise, vibration, durability, manufacturing difficulty, etc. It is designed for the purpose of inexpensive engine of low pollution, high fuel efficiency, intermittent combustion cycle.

상술한 목적을 달성하기 위하여 왕복동 내연기관의 결점인 관성저항을 제거하고 소음,진동,마찰력으로 인한 기계적 손실 등을 개선하고 간단한 구조로서 마력당 중량 및 부피를 줄이고 내구성 및 생산원가를 절감한 고연비의 로우터리 엔진을 개발한다.In order to achieve the above-mentioned purpose, the inertia resistance, which is a drawback of the reciprocating internal combustion engine, is eliminated, and the mechanical loss due to noise, vibration, and friction is improved, and the simple structure has reduced the weight and volume per horsepower, and reduced the durability and production cost. Develop a rotary engine.

도면중 미설명부호 16은 플라이 휘일(fly wheel), 17은 가스실(gas seal) 18은 에어쿳션(Air Cushion), 19는 체크밸브(check valve)를 표시한 것이다.In the drawings, reference numeral 16 denotes a fly wheel, 17 a gas seal 18, an air cushion, and 19 a check valve.

이상과 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

편심로우터(3)의 가스실(gas seal)(17)부분이 하우징(4)의 내면에 접촉하면서 회전할 때 날개밸브(8)의 하단은 로우터(3)상면에 밀접된 상태로 안내홈(6)내에서 긴밀히 상하운동 하고 공기흡입구(14)에서 미리 흡입된 공기는 하우징(4)내 용적 변화와 함께 압축되어서 입구(9')를 통하여 공기실(9)내로 압송되고, 이 압축공기는 체크밸브(19)에 의하여 역류(逆流)를 방지한다. 공기를 최대한 으로 압축하여 편심로우터(3)가 좌측의 공기실(9)입구(9')를 완전히 가로막아서 또 로우터(3)의 가스실(17)이 상방 하우징(4)내벽에 밀접할 무렵에는 날개밸브(8)중간의 공기공(7)이 좌우양측의 측벽공(10)(10')과 포개지므로, 공기실(9)내의 압축공기는 우측의 연소실(11)내로 급속히 유출하여 우측 하우징(4)에 밀접회전 하는 하방의 로오터(3)면까지 충만되고, 날개밸브(8)가 약간 하강하여 공기공(7)이 측벽공(10)(10')과 어긋나는 순간에는 분사연료변(12)으로부터 분사하는 연료가 연소실(11)에 충만된 압축공기와 격돌하여 혼합되면서 점화플러그(13)에 의하여 점화되면서 고온고압의 연소가스가 편심의 로우터(13)표면에 강력히 작용하여 토오크(torque)가 발생한다.When the gas seal 17 portion of the eccentric rotor 3 rotates while contacting the inner surface of the housing 4, the lower end of the wing valve 8 is in close contact with the upper surface of the rotor 3. The air moves up and down tightly in the cavity) and the air sucked in advance at the air intake port 14 is compressed with the volume change in the housing 4 to be compressed into the air chamber 9 through the inlet 9 ', and the compressed air is checked. The valve 19 prevents backflow. When the air is compressed to the maximum, the eccentric rotor 3 completely blocks the inlet 9 'of the air chamber 9 on the left side and the gas chamber 17 of the rotor 3 is in close contact with the inner wall of the upper housing 4. Since the air hole 7 in the middle of the wing valve 8 overlaps with the side wall holes 10 and 10 'on both the right and left sides, the compressed air in the air chamber 9 rapidly flows into the combustion chamber 11 on the right side and the right housing Filled to the lower rotor (3) surface close to (4), the wing valve (8) is slightly lowered when the air hole (7) is shifted from the side wall hole (10, 10 ') injection fuel valve The fuel injected from (12) collides with the compressed air filled in the combustion chamber (11) and is ignited by the spark plug (13), so that the combustion gas of high temperature and high pressure acts strongly on the surface of the eccentric rotor (13) and torque ( torque) occurs.

따라서 로우터(3)의 출력축(2)은 화살표 방향으로 원활하게 회전운동을 지속하고 팽창연소 가스는 배기구(15)로 신속히 배출한다.Therefore, the output shaft 2 of the rotor 3 continues the rotational movement smoothly in the direction of the arrow, and the expanded combustion gas is quickly discharged to the exhaust port 15.

그리고 안내홈(6)정상의 에어쿳션(Air Cushion)내에 윤활유를 약간식 주입하면(不圖示) 날개판자(6)를 유막으로 윤활하고 로우터(3)에 흘러내려서 하우징(4)밑바닥에 낙하한다.When the lubricant is slightly injected into the normal air cushion of the guide groove 6, the wing plate 6 is lubricated with an oil film, flows into the rotor 3, and falls to the bottom of the housing 4. do.

이와같이 하우징(4)밑바닥에 고인 윤활유는 회전하는 로우터(3)가 하우징(4)내벽면에 접촉하면서 회전할 때, 그 회전방향으로 급속히 밀어 올려서 하우징(4)내벽으로 비산(飛散)케 하므로 로우터(3)와의 마찰 마모 및 과열을 방지한다.In this way, when the rotor 3 rotates while the rotating rotor 3 contacts the inner wall surface of the housing 4, the lubricant accumulated on the bottom of the housing 4 is rapidly pushed up in the direction of rotation so as to scatter on the inner wall of the housing 4. (3) to prevent friction wear and overheating.

이상과 같이 본 발명은 로우터(3) 1회전에 한번 연소하는 비폭발성 간헐 연소사이클을 원활하게 수행하므로 진동,소음이 없고 날개밸브(8)하단은 그 자중(自重)과 에어쿳션(18)내의 공기탄력에 의하여 로우터(3)면에 밀접된 상태로 안내홈(6)내에서 상하운동 하고, 또 로우터(3)의 가스실(17)부분과 하우징(4)내면과의 접촉면적이 넓어서 기밀(氣密)이 확보되기 때문에 출력이 향상되고 연비가 높아진다.As described above, the present invention smoothly performs the non-explosive intermittent combustion cycle that burns once per revolution of the rotor 3, and thus, there is no vibration and noise, and the lower end of the wing valve 8 has its own weight and inside the air cushion 18. It moves up and down in the guide groove 6 in a state in which it is in close contact with the surface of the rotor 3 by air elasticity, and the contact area between the gas chamber 17 part of the rotor 3 and the inner surface of the housing 4 is wide, so that the airtight (氣密) is secured, output is improved and fuel economy is increased.

본 발명을 실시함에 있어서 에어쿳션(18)내에 코일스프링을 장착해도 무방하다.In implementing the present invention, a coil spring may be mounted in the air cushion 18.

본 발명은 왕복동 내연기관(reciprocating engine)과 같은 크랭크 기구가 없이 하우징(4)내에서 로우터(3)를 직접 회전 운동케 하였으므로 기계적 효율이 높고, 피스톤 왕복운동의 관성저항이 제거되고, 소음과 진동이 거의 없으며 날개밸브 (8)의하단은 로우터(3)상면에 밀접되고 또 로우터(3)의 가스실(17)부분과 하우징(4)내벽과의 접촉면적이 넓기 때문에 기밀이 확보되므로 출력향상으로 연비가 높아지고 또 구조가 극히 간단하여 내구성이 높고, 마력당 중량 및 부피가 작고, 제작성이 용이하여 생산 원가가 크게 절감되고 연소실(11)내에서는 비교적 저온연소를 하므로 질소산화물(NOx)등 공해가스배출이 저감되는 효과가 있다.In the present invention, since the rotor 3 is directly rotated in the housing 4 without a crank mechanism such as a reciprocating engine, the mechanical efficiency is high, the inertia resistance of the piston reciprocating motion is eliminated, and noise and vibration Since the lower end of the wing valve 8 is close to the upper surface of the rotor 3 and the contact area between the gas chamber 17 portion of the rotor 3 and the inner wall of the housing 4 is wide, airtightness is secured, thereby improving output. High fuel efficiency and extremely simple structure, which is high in durability, small in weight and volume per horsepower, and easy to manufacture, greatly reducing production costs and relatively low temperature combustion in the combustion chamber 11. Gas emissions are reduced.
