A pair of rotors are fixed, at the center thereof, to the output shaft and arranged eccentrically in respective chambers such that the rotors rotate while sliding, at a part of the circumferential surface thereof, on the inner circumferential surface of the chamber. A shield plate is fitted slidably in the radial direction of the shaft of each rotor and urged resiliently such that the forward end thereof abuts against the inner circumferential wall of the chamber. One chamber has a fuel suction port communicating with a void on one side in the rear of the rotor sliding part, and a compressed gas delivery port communicating with a void on the other side in front of the rotor sliding part. The other chamber has an explosion gas jet port opened to a microgap in the vicinity of the rear end at the rotor sliding part, and a combustion gas exhaust port communicating with a void in front of the rotor sliding part. The compressed gas delivery port and the explosion gas jet port are allowed to communicate through a compressed gas accumulation passage provided with an ignition chamber. Phase angle of the pair of rotors is set such that the shield plate of the other rotor is located in front of the microgap of the explosion gas jet port when the shield plate of one rotor compresses fuel gas at a desired compression ratio.

技術分野 Technical field
本発明は軽量小形で相対的に大きな出力を得ることができ、 しかも、 製作が容 易な同軸回転エンジンに関する。 The present invention relates to a coaxial rotary engine that is lightweight and small, can obtain a relatively large output, and is easy to manufacture.
背景技術 Background art
従来のレシプロエンジンは所定ストロ一クのシリンダを使用するため、 相対的 に大形となる。 また、 シリンダの 2往復でエンジンが 1サイクルとなるため、 出 力効率の点で問題があり、 燃料コストも相対的に髙くつく。 Conventional reciprocating engines are relatively large because they use cylinders of a predetermined stroke. Also, since the engine makes one cycle with two reciprocations of the cylinder, there is a problem in output efficiency, and the fuel cost is relatively high.
エンジンケ一シングに凹凸曲面を有する回転円盤と非回転の受け盤を、 その凹 凸曲面を対向させて同軸に配置し、 回転円盤の回転によって生ずる凹凸曲面間の 一対の容積可変チャンバで燃料を吸気、 圧縮、 膨張、 排気させるようにした回転 エンジンが本願発明者によって開発され、 特開平 1 0— 2 0 5 3 4 4として開示 されている。 また、 この日本特許公開に対応する米国特許第 5 8 3 6 2 8 6号及 び米国特許第 6 0 3 2 6 3 6号がある。 A rotating disk having a concave and convex curved surface and a non-rotating receiving disk are arranged coaxially in engine casing with the concave and convex curved surfaces facing each other, and fuel is supplied to a pair of variable volume chambers between the concave and convex curved surfaces generated by rotation of the rotating disk. A rotating engine adapted to intake, compress, expand and exhaust has been developed by the present inventor and disclosed in Japanese Patent Application Laid-Open No. H10-2005-344. There are also US Pat. No. 5,836,286 and US Pat. No. 6,326,36 corresponding to the Japanese patent publication.
上記の公知回転エンジンは回転円盤の回転に伴って、 一対のチヤンバで庄縮と 排気を同時に行い、 また、 膨張と吸気を同時に行うものであるが、 容積可変のチ ヤンバが回転方向に一段しか形成されていない構造であるため、 膨張 (爆発) の エネルギーを次の庄縮の力に持続させる際に力が不足し、 回転が不安定になるお それがあった。 In the above-described known rotary engine, contraction and exhaust are simultaneously performed by a pair of chambers and expansion and intake are performed simultaneously with the rotation of the rotating disk, but the variable volume chamber is only one stage in the rotation direction. Because the structure was not formed, the power was insufficient when sustaining the energy of expansion (explosion) to the force of the next contraction, and rotation could become unstable.
また、 上記の回転エンジンは回転円盤と固定円盤の対向面を気密を保持して円 滑に摺接する凹凸曲面に形成する必要があるが、 このような凹凸曲面の加工 ·組 付けには高度の技術を要するため、 製品の歩留まり、 コスト髙などの問題もあつ た。 Also, in the above-mentioned rotary engine, it is necessary to form the confronting surface of the rotating disk and the fixed disk into an uneven curved surface that slides smoothly while maintaining airtightness. Because of the need for technology, there were also issues such as product yield and cost.

以下に、 本発明の実施例を添付の図面に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
第 1図〜第 3図に示すように、 本発明による同軸回転エンジン 1のケーシング 2は、 仕切リ壁 3に区画されて所定巾の円形又は楕円形の内周壁を有する一対の チャンバ 4、 5 (以下、 第 1チャンバ 4、 第 2チャンバ 5という) を備えている ケ一シング 2の軸方向に回転出力軸 6が偏心位置を貧通して回転自在に配設さ れている。 As shown in FIGS. 1 to 3, a casing 2 of a coaxial rotary engine 1 according to the present invention includes a pair of chambers 4 and 5 partitioned by a partition wall 3 and having a circular or elliptical inner peripheral wall having a predetermined width. (Hereinafter, referred to as a first chamber 4 and a second chamber 5). A rotary output shaft 6 is rotatably arranged in the axial direction of the casing 2 so as to pass through an eccentric position.
第 1及び第 2チャンバ 4、 5には、 該チャンバ 4、 5よりも小径の円盤からな るロータ 7、 8が回転出力軸 6に中心を固定して同軸に一体回転可能に設置され ている。 In the first and second chambers 4 and 5, rotors 7 and 8 made of disks smaller in diameter than the chambers 4 and 5 are installed so as to be coaxially and integrally rotatable with the center fixed to the rotary output shaft 6. .
また、 第 1及び第 2 α—タ 7、 8は円形外周面の一部が各チャンバ 4、 5の内 周壁面に気密に摺接して回転し、 摺接部 1 3以外の円形外周面とチャンバ内周壁 面の間に空所 9が形成されるようにして配設されている。 In addition, the first and second α-motors 7 and 8 rotate partly in a circular manner in contact with the inner peripheral wall surface of each of the chambers 4 and 5 while rotating a part of the circular outer peripheral surface. The space 9 is provided so as to form a space 9 between the inner peripheral wall surfaces of the chamber.
第 1及び第 2ロータ 7、 8は外側から中心に向けて延びる半径方向の溝 1 0を 軸方向に沿って形成してあり、 この溝 1 0内にばね 1 1によって外側へ付勢され た遮蔽板 1 2が摺動自在に嵌装されている。 The first and second rotors 7, 8 are formed with a radial groove 10 extending from the outside toward the center along the axial direction, and are urged outward by a spring 11 in the groove 10. The shielding plate 12 is slidably fitted.
この構成により各々の遮蔽板 1 2はばね 1 1によりチヤンバ内周壁に向けて付 勢され、 その先端を対応のチャンバ 4、 5の内周壁に気密に摺接しながら各々の ロータ 7、 8と一体にチャンバ 4、 5内を回動するようになっている。 With this configuration, each shielding plate 12 is urged toward the inner peripheral wall of the chamber by the spring 11, and the tip thereof is integrated with each of the rotors 7 and 8 while sliding in airtight contact with the inner peripheral walls of the corresponding chambers 4 and 5. The inside of the chambers 4 and 5 is rotated.
第 1チャンバ 4は、 ロータ 7との摺接部 1 3の後方近傍に、 前記チャンバ空所 9の一側に連通する燃料ガス吸入口 1 4を形成してあるとともに、 摺接部 1 3の
手前近傍に前記チヤンバ空所 9の他側に連通する圧縮ガス吐出口 1 5を形成して ある。 The first chamber 4 has a fuel gas inlet 14 communicating with one side of the chamber space 9 near the rear of the sliding contact portion 13 with the rotor 7. A compressed gas discharge port 15 communicating with the other side of the chamber 9 is formed near this side.
図の実施例ではロータ 7、 8は時計回りに設定されており、 図面上、 摺接部 1 3の右側近傍にチヤンバの空所 9に連通する吸入口 1 4を設け、 摺接部 1 3の左 側近傍にチャンバの空所 9に連通する圧縮ガス吐出口 1 5を設けてある。 In the embodiment shown in the figure, the rotors 7 and 8 are set clockwise. In the drawing, a suction port 14 communicating with the cavity 9 of the chamber is provided near the right side of the sliding contact portion 13, and the sliding contact portion 13 is provided. A compressed gas discharge port 15 communicating with the cavity 9 of the chamber is provided near the left side of the chamber.
このため、 ケ一シング 2の第 1チャンバ 4では、 第 1ロータ 7の回転により遮 蔽板 1 2の先端が第 1チャンバ 4の内周壁に気密に当接して回動することにより 、 燃料ガスの吸入工程と圧縮工程が同時に進行する。 Therefore, in the first chamber 4 of the casing 2, the tip of the shielding plate 12 is brought into airtight contact with the inner peripheral wall of the first chamber 4 by the rotation of the first rotor 7, and the fuel gas is turned off. The suction step and the compression step proceed simultaneously.
他方、 第 2チャンバ 5は、 ロータ 8との摺接部 1 3の後端の微小隙間に爆発ガ ス噴射口 1 6を開口させてあるとともに、 摺接部 1 3の手前近傍に前記チヤンバ 空所 9に連通する燃焼ガス排気口 1 7を形成してある。 すなわち、 図面上では、 第 2ロータ 8との摺接部 1 3の右側の微小隙間に爆発ガス噴射口 1 6を開口させ 、 摺接部 1 3の左側近傍にチヤンバの空所 9に連通する燃焼ガス排気口 1 7を設 けてある。 On the other hand, the second chamber 5 has an explosion gas injection port 16 opened in a minute gap at the rear end of the sliding contact portion 13 with the rotor 8, and the chamber vacant near the sliding contact portion 13.

第 1ロータ 7と第 2ロータ 8の位相角は、 第 3図にしめすように、 第 1ロータ 7の遮蔽板 1 2が燃料ガスを所望の圧縮比に圧縮した位置にあるとき、 すなわち, 図の実施例では燃料ガス吸入口 1 4の近傍に位置するときに、 第 2ロータ 8の遮 蔽板 1 2が爆発ガス噴射口 1 6の前記微小隙間のわずか前方に位置し、 これによ リ、 所望の圧縮比に圧縮した燃料ガスの爆発 (膨張) で、 第 2 ロータ 8の遮蔽板
1 2が最大の爆発圧力を受けるように設定する。 As shown in FIG. 3, the phase angle between the first rotor 7 and the second rotor 8 is determined when the shielding plate 12 of the first rotor 7 is at a position where the fuel gas is compressed to a desired compression ratio. In this embodiment, when located near the fuel gas inlet 14, the shielding plate 12 of the second rotor 8 is located slightly forward of the minute gap of the explosive gas injection port 16, The explosion (expansion) of the fuel gas compressed to a desired compression ratio causes the shielding plate of the second rotor 8 to expand. Set 1 2 to receive maximum explosion pressure.
第 2チャンバ 5の爆発ガス噴射口 1 6は、 第 2ロータ 8との摺接部 1 3後端の 微小隙間に対向し、 通路が絞られているので、 第 1チャンバ 4のロータ 7の遮蔽 板 1 2によって圧縮された燃料ガスは圧縮ガス溜め通路 1 8に押し込められて圧 縮されている。 このように、 燃料ガスが圧縮された状態で第 2ロータ 8の遮蔽板 1 2が爆発ガス噴射口 1 6の微小隙間前方にあって、 プラグ 2 1が点火されると 圧縮燃料ガスの爆発により、 第 2ロータ 8が第 1ロータ 7及び出力軸 6と一体に 回転する。 The explosive gas injection port 16 of the second chamber 5 opposes the small gap at the rear end of the sliding contact portion 13 with the second rotor 8, and the passage is restricted, so that the rotor 7 of the first chamber 4 is shielded. The fuel gas compressed by the plate 12 is pushed into the compressed gas reservoir passage 18 and compressed. In this way, when the fuel gas is compressed, the shield plate 12 of the second rotor 8 is located in front of the small gap of the explosion gas injection port 16 and when the plug 21 is ignited, the explosion of the compressed fuel gas causes The second rotor 8 rotates integrally with the first rotor 7 and the output shaft 6.
かく して、 本発明の同軸回転エンジン 1は、 吸入行程と圧縮行程を同時進行さ せる第 1 ロータ 7と、 爆発 (膨張) 行程と排気行程を同時進行させる第 2ロータ 8と、 吸入行程と圧縮行程を同時進行させる第 1 ロータ 7が共通の回転軸 6に固 定されて同軸に回転し、 且つ、 第 1チャンバ 4の圧縮ガス吐出口 1 5と爆発ガス 噴射口 1 6が圧縮ガス溜め通路 1 8を介して連通しているので、 各ロータ 7、 8 に各 1個の遮蔽板 1 2を設けた第 1図〜第 3図の実施例では、 口一タ 7、 8の一 回転で吸入、 圧縮、 爆発及び排気の 4行程が同時に完遂される。 しかも、 第 1チ ヤンバ 4における燃料ガスの圧縮は第 2チャンバ 5の爆発力を利用して行われる ので、 圧縮抵抗でエンジンが停止することなく安定した出力が発生する。 この場 合、 燃料ガスの圧縮に爆発エネルギーの一部が消費されるが、 単位当りの圧縮ガ スの爆発エネルギーは、 圧縮に必要なエネルギーのおよそ 2 0 0倍であるから、 爆発力になんらま障はない。 Thus, the coaxial rotary engine 1 of the present invention includes a first rotor 7 for simultaneously performing an intake stroke and a compression stroke, a second rotor 8 for simultaneously performing an explosion (expansion) stroke and an exhaust stroke, and a suction stroke. The first rotor 7 for simultaneously proceeding the compression stroke is fixed to the common rotation shaft 6 and rotates coaxially, and the compressed gas discharge port 15 and the explosive gas injection port 16 of the first chamber 4 store compressed gas. Since each of the rotors 7 and 8 is provided with one shielding plate 12 because of the communication through the passage 18, one rotation of the mouth 7 and 8 is performed in the embodiment of FIGS. 1 to 3. The four processes of suction, compression, explosion and exhaust are completed simultaneously. Moreover, since the compression of the fuel gas in the first chamber 4 is performed using the explosive power of the second chamber 5, a stable output is generated without stopping the engine due to the compression resistance. In this case, a part of the explosion energy is consumed for the compression of the fuel gas, but the explosion energy of the compression gas per unit is approximately 200 times the energy required for the compression. There is no obstacle.

になる。 また、 各々のロータ 7、 8に対の遮蔽版 1 2 a、 1 2 bが対称形に設け られているので、 作動中のバランスがよい。 In this embodiment, the plug 21 is ignited each time the pair of shield plates 12 a and 12 b of the rotor 8 of the second chamber 5 passes through the explosive gas injection port 16. . Therefore, in this embodiment, two explosions (expansion) occur each time the rotors 7 and 8 and the rotary output shaft 6 make one revolution, and two cycles of engine operation work every one revolution. become. In addition, since the pair of shield plates 12a and 12b are provided symmetrically on each of the rotors 7 and 8, the balance during operation is good.
第 4図〜第 5図の実施例は、 各々のロータ 7、 8の相対する 2ケ所の半径方向 に一対の遮蔽板 1 2 a、 1 2 b を嵌装する場合を例示したが、 各ロータ 7、 8の 相対する半径方向に複数対又は複数個の遮蔽板を設けることにより、 1回転の間 のエンジンサイクルを比例的に増加させることができる。 The embodiment of FIGS. 4 to 5 illustrates a case where a pair of shield plates 12 a and 12 b are fitted in two opposite radial directions of the respective rotors 7 and 8. By providing a plurality of pairs or a plurality of shielding plates in the radial directions opposite to each other, the number of engine cycles during one rotation can be proportionally increased.
尚、 図の実施例は、 本発明の同軸回転エンジンをガソリンエンジンとして使用 する場合を例示し、 圧縮ガス溜め通路 1 8の点火室 2 0にプラグ 2 1を使用して いるが、 本発明の同軸回転エンジンはヂ一ゼルエンジンとして使用することも可 能であり、 その場合はプラグを省唣することができる。 The embodiment shown in the figure illustrates a case where the coaxial rotary engine of the present invention is used as a gasoline engine, and the plug 21 is used in the ignition chamber 20 of the compressed gas reservoir passage 18. The coaxial rotating engine can be used as a diesel engine, in which case the plug can be omitted.
また、 図の実施例は、 回転軸に 1組の前記エンジンを取り付けた場合を例示し ているが、 本発明は前記の同軸回転エンジンを共通の回転軸に取付けた複合回転 エンジンに構成することも可能であり、 これによりエンジン出力を増強させるこ とができる。 産業上の利用可能性 Further, although the embodiment of the figure illustrates a case where one set of the engines is mounted on a rotating shaft, the present invention provides a composite rotating engine in which the coaxial rotating engine is mounted on a common rotating shaft. It is also possible to increase the engine output. Industrial applicability
