로터리 피스톤 엔진의 케이싱 씰 장치Casing seal device of rotary piston engine

제1도는 본 고안에 관한 케싱 장치를 갖춘 로터리 피스톤 엔진의 수직 절단 측면도1 is a vertical cutaway side view of a rotary piston engine with a casing device according to the present invention

제2도는 제1도를 Ⅱ-Ⅱ선상에서 절단한 요부의 정면도.FIG. 2 is a front view of the main portion of FIG. 1 taken along line II-II. FIG.

제3도는 제2도의 Ⅲ-Ⅲ절단확대 측면도.3 is an enlarged side view of cut III-III of FIG.

본 고안은 로터리 피스톤 엔진의케이싱 씰 장치에 관한 것으로 특히 싸이드 하우징과 로우터 하우징과에 각기 냉각액 통로를 두어 냉각액이 냉각액 통로 상호간에 관류되도록 한케이싱에 있어서 작동실내의 연소가스가 로우터 하우징과 싸이드 하우징과의 접합부의 간격으로 칩입하여 접합부에 기재된 씰 부재에 악영향을 미치게 되는 것을 방지하기 위한 로터리 피스톤 엔진의 케이싱 씰 장치에 관한 것이다.The present invention relates to a casing seal device of a rotary piston engine. In particular, in a casing in which a coolant passage is provided in the side housing and the rotor housing so that the coolant flows through the coolant passages, the combustion gas in the operating chamber is separated from the rotor housing and the side housing. It relates to a casing seal device of a rotary piston engine for preventing chipping at intervals of the joint portion of the joint to adversely affect the seal member described in the joint portion.

일반적으로 다원호상(多圓弧狀)의 내면을 갖인 로우터 하우징과 좌우 양면에 배치된 싸이드 하우징으로 된 케이싱 중을 다각형상의 로우터가 유성(遊星)회전운동하여, 작동유체의흡입압축, 폭발, 팽창 및 배출의 각 행정(行程)을 하도록 로우터리 피스톤 엔진에 있어서는, 로우터의 측면에 장착하여 싸이드 하우징과의 사이의 기밀을 유지하는 코너 씰, 싸이드씰 및 오일 씰 등 씰 장치의 허용 추종량을 소저으이 수치로 유지시켜 로우터와 싸이드 하우징과의 사이의 기밀을 확실히 유지시키기 위해 싸이드 하우징 상호간에는 극히 높은 칫수 정도가 요구되고, 또 싸이드 하우징과 로우터 하우징의 접합부에는 냉각액 통로에서 작동실 까지의 냉각수의 누설을 막기위해 높은 수밀성이 요구되는 것이다.In general, a rotor of a polygonal shape is rotated by a planetary rotor in a casing consisting of a rotor housing having a plurality of arc-shaped inner surfaces and a side housing disposed on both left and right sides thereof, so that suction fluid compression, explosion, and expansion of a working fluid are performed. In the rotary piston engine, the allowable following amount of seal devices such as corner seals, side seals, and oil seals, which are mounted on the side of the rotor to maintain airtightness with the side housings, is used to perform each stroke of the discharge. In order to maintain this value to ensure airtight between the rotor and the side housing, extremely high dimensions are required between the side housings, and the junction of the side housing and the rotor housing has leakage of coolant from the coolant passage to the operating chamber. High water tightness is required to prevent this.

그리고 이러한 종류의 엔진의 케이싱은 종전 싸이드 하우징의 측면과 로우터 하우징과의 측면을 직접 접합하고, 그 접합부에 밀착성이 우수한 고무제 0링을 삽입 체결시켜 상술한 바와같은 요구를 만족시키고 있다. 그러나 종래의 것에 있어서는 싸이드 하우징과 로우터하우징이 직접 접합되어 있어, 그 접합부에는 근소한 간격이 생겨 이 간격에 작동실내의 고온 고압가스가 칩입하여 그 접합부의 바깥쪽에 위치한 0링을 열화(소손)시켜, 그 결과 냉각액 통로내의 냉각액이 작동실내에 칩입된다는 엔진이 있어서 치명적인 문제를 야기시켰던 것이다.The casing of this type of engine satisfies the above-mentioned requirements by directly joining the side of the conventional side housing to the side of the rotor housing and inserting and engaging a rubber 0 ring having excellent adhesion to the joint. However, in the conventional case, the side housing and the rotor housing are directly bonded to each other, and a slight gap is formed at the junction, and high-temperature and high pressure gas in the operating chamber enters the gap, degrading (burning out) the zero ring located outside the junction. As a result, there is an engine that causes the coolant in the coolant passages to penetrate the operating chamber, causing a fatal problem.

본 고안은 이러한 문제점을 시정하고자 안출한 것으로 케이싱의 결합부에 고무제의 주체의 표면 일부에 배후론등의 내열층을 일체적으로 설치한 셀 부재를 그 내열층을 작동실측으로 향하도록 하고, 또 상기 주체를 각 접합면에 밀착되게 장착하여 상술한 결점을 해결코자 하는 것이다.The present invention has been made to correct this problem, and the cell member having integrally installed a heat-resistant layer such as a backing on a part of the surface of the rubber main body at the joint portion of the casing is directed to the heat-resistant layer toward the operating room side, In addition, to solve the above-described drawbacks by mounting the main body in close contact with each joining surface.

첨부된 도면에 의해 본 고안의 한 일 실시예를 설명한다.An embodiment of the present invention will be described with reference to the accompanying drawings.

제1도 및 제2도에서 로우터의 피스톤 엔진은 케이싱 1과 편심축에서 지승되어, 케이싱 1내를 유성회전운동하는 로우터 2가 있고, 로우터 2의 회전에 의해 흡입구에서 자동유체를 작동실3 내에 흡입하여, 그작동 유체를 압축, 폭발의 각 행정을 거쳐 배기구(도시하지 않음)에서 배기가스로서 배출하도록 구성되어 있다.The piston engine of the rotor in Figs. 1 and 2 has a rotor 2 which is driven on the eccentric shaft with the casing 1, and has a rotor 2 for planetary rotational movement in the casing 1, and the automatic fluid is introduced into the operating chamber 3 at the inlet by the rotation of the rotor 2. It is configured to inhale and discharge the working fluid as exhaust gas through an exhaust port (not shown) through compression and explosion.

이 케이싱 1은 다원호상의 내면을 갖는 로우터 하우징 4와 그 양측에 위치하는 싸이드 하우징 5로 구성되어 있다. 이 로우터 하우징 4와 싸이드 하우징 5는 축방향에 있어서 다수의 채부볼트 6에 의해 일체로 접합되어 있다.The casing 1 is composed of a rotor housing 4 having an inner surface of a plurality of arcs and a side housing 5 located on both sides thereof. The rotor housing 4 and the side housing 5 are integrally joined by a plurality of mounting bolts 6 in the axial direction.

로우터 하우징 4는 내벽부 7과 외벽부 8을 주 방향으로 소정간격을 유지하여, 리브 9또는 볼트보스10에 의해 일체적으로 결합구성되고, 내부에 싸이드 하우징 5의 냉각액통로 11에 대향하는 냉각액통로 12를 갖이고 있다. 그 내벽부 7의 측면축 로우터 하우징 축 접합면 13에는 쎌 부재 14를 장착하는 환상의 셀홈 15를 갖추고 있다.The rotor housing 4 maintains a predetermined distance in the main direction between the inner wall portion 7 and the outer wall portion 8, and is integrally coupled with the ribs 9 or the bolt boss 10, and has a cooling liquid passage opposed to the cooling liquid passage 11 of the side housing 5 therein. Has 12. The side shaft rotor housing shaft joining surface 13 of the inner wall portion 7 is provided with an annular cell groove 15 for mounting the fin member 14.

셀부재 14는 제3도와 같이 고무재의 주체 16으 표면일부에 배후론등의 내열층 17이 일체적으로 형성되어 있다. 이 셀 부재 14는 그 내열층 17을 작동실측으로 향하게 하고, 또 주체 16을 싸이드 하우징 4의 접합면에 밀착시켜 장착되있다. 이 경우 셀 부재 14의 단면 형상은 각형이어도 좋고, 둥근형이어도 좋으나 각형은 원통상으로 형성한 것을 연속적으로 절단하면 되므로 코스트면이 유리하다. 또 내열층으로서는 데후론등의 내열 합성 수지뿐 아니라 동 또는 강등의 금속도 좋다. 고무재의 주체를 열적으로 방호하는 것이면 된다.As shown in FIG. 3, the cell member 14 is integrally formed with a heat-resistant layer 17 such as a background theory on a part of the surface of the main body 16 of the rubber material. The cell member 14 faces the heat-resistant layer 17 toward the operating chamber side and is mounted by bringing the main body 16 into close contact with the joining surface of the side housing 4. In this case, the cross-sectional shape of the cell member 14 may be square or round, but the square is advantageous in that it is necessary to cut continuously what is formed in a cylindrical shape. As the heat-resistant layer, not only heat-resistant synthetic resins such as deferon but also metals such as copper or steel may be used. What is necessary is just to thermally protect the main body of a rubber material.

본 고안은 이상의 설명에서 명백한 바와같이 고부재의 주체 표면 일부에 태후론등의 내열층을 일체적으로 둔 씰 부재를 내열측을 작동실축으로 향하게 하고, 또 상기한 주체를 각 접합면에 밀접시켜 로우터 하우징과 싸이드 하우징의 접합부에 장착하고, 밀착성이 좋은 고무제의 주체에 의해 냉각수 작동실내의 누설을 확실히 막고, 또 씰부재의 연소갓에 의한 열적 악영향을 내열측으로 방호하게 한 것이기 때문에 연소가스에 의한 씰부재의 열화가 방지되어 냉각에 통로에서 작동실에 냉각액 누설을 막을수 있어 엔진의 수명을 현저히 연장시키는 것이다.The present invention, as is apparent from the above description, the seal member having a heat-resistant layer such as Talonron on a part of the surface of the main body of the solid member, with the heat-resistant side facing the working axis, and the main body close to each joint surface. It is attached to the joint of the rotor housing and the side housing, and the rubber main body prevents leakage in the coolant operating chamber and protects the thermal adverse effects of the seal member from the combustion shade on the heat-resistant side. This prevents the seal member from deteriorating and prevents leakage of the coolant from the cooling chamber to the operating chamber, thereby significantly extending the life of the engine.

또 본 고안의 셀 부재의 주체와 내열층과의 일체로 형성하고 있어 셀 홈의 장치에 있어서도 종전의 셀부재를 장착하는 경우에 비해 별다른 난점이 없이 간단하게 할수 있는 것이다.In addition, since the main body of the cell member of the present invention and the heat-resistant layer are integrally formed, the cell groove device can be simplified without any difficulty compared to the case where the conventional cell member is mounted.
