以下结合附图及较佳实施例， 对依据本发明提出的回转式内燃 机的具体技术内容、 结构、 特征及功效， 详细说明如后。
首先以图 2 1 至图 2 5 本发明的一种回转式内燃机的基本循环 动作图来说明本发明的动作：
此为内燃机运转时的基本简单线形， 说明如诃将压缩缸内的髙 压气体压入动力缸供其点火产生动力，请参阅图 2 1 、 图 2 2 所示， 图 2 1 左半图为压缩缸 6 1 , 右半图为动力缸 6 2 , 使两缸重叠成 为同一圆心； 在两缸间连接以一气体管道 2 8 , 可选最短距离， 使 其气体相通， 并将压缩缸 6 1 的压缩杆 3 4 及动力缸 6 2 的动力杆 3 5 加以固定。 当其依箭头方向转动时， 该压缩杆 3 4 将一压缩缸 6 1 内的高压气体经由管道 2 8 压入右侧动力缸 6 2 内。 若在偏心 体 1 4 的周边加装气刀 3 7 , 预留若干角度缺口， 转动时， 以气刀 3 7 切割管道 2 8 , 使管道 2 8 作开启及关闭的动作， 而使气体执 行供应或停止的动作。 该缺口的宽窄设计可控制缸内气体压力的高 低， 亦等于控制压缩比。 当内燃机转动， 经图 2 2 位置到达图 2 3 位置时， 压缩缸 6 1 内的髙压气体全部进入右侧的动力缸 6 2 内， 同时气刀 3 7 上的缺口通过了管道 2 8 , 即关闭了管道 2 8 的通 路， 防止了动力缸 6 2 内的气体倒流回压缩缸 6 1 。 当压缩杆 3 4 继续转动少许角度， 即点火燃烧气体， 产生动力， 转动内燃机。 当 到达图 2 4 位置时， 此为压缩缸 （第三压缩缸压缩纯空气） 与动力 缸的动作， 其动作流程完全与前述过程相同， 唯一不同的是， 压缩 缸 6 3 的高压气体 6 3 , 即高压纯空气供入该动力缸 6 2 的时间， 纯空气注入动力缸 6 2 的时间， 是在点火后 （燃烧中） ， 此动作可 加强燃烧动力缸 6 2 中的混合气， 便其达剁与力增加及静化废气的 效果。 请特别注意图 2 4 所示， 此时压缩缸 6 3 与图 2 1 的压缩缸 6 1 体积形状及角度完全相同， 两气刀 3 7 及气刀 3 8 的构造亦完 全相同。 由此视之， 三个压缩杆 3 4 、 3 5 、 3 6 固定成可转动的 Y字形角度， i靑再参阅图 2 5 所示， 此时气刀 3 8 关闭管道 2 9 , 其动作、 目的及劝效与图 2 2 中的气刀 3 7 及管道 2 8 完全相同， 同样为了达到防止气体逆流的效果。 同时动力缸 6 2 的体积及角度 增大， 若将动力 （燃烧） 角度大小与其他引擎比较， 本发明大于 1 8 0 度， 活塞引擎小于 1 8 0 度， 温哥 Wa n k e 1 引擎小于 1 2
0 度。
以下由图 1 至图 5 来说明本发明内燃机的基本构造。 该单只压 缩机的基本构造如图 1 所示， 主要零件包括有三件： 一压缩杆 2
1 、 一偏心体 3 4 ， , 及一外壳 1 0 所组成。 该压缩杆 2 1 固定于 主轴 2 0 上， 主轴 2 0 与外壳 1 0 同一轴心， 主轴 2 0 两端各装有 轴承 1 7 (如图 2 所示） ， 轴承 1 7 支捭于两侧壳盖 1 3 上的轴承 座内。 婧参阅图 2 至图 5 所示， 偏心体 3 4， 、 3 5 ， 、 3 6 ， 同 为中空圆柱体， 在该圆柱体上凿有一圆体座， 其内装有导体 2 4、
2 5 , 2 6 , 导体中有方孔， 分别套设于压缩杆 2 1 、 2 2、 2 3 上， 转动时， 各导体 2 4 , 2 5 , 2 6 在偏心体 3 4， 、 3 5 ， 、
3 6 ， 上作少许角度正逆回转， 同时与压缩杆 2 1 、 2 2、 2 3 作 往复运动， 两端压缩机的偏心体 3 4 ' 、 3 6 ' 的外廊装有气刀 3 7 , 3 8 (如图 2 至图 5 所示） ， 转动时， 气刀 3 7 , 3 8 在刀沟 内切割管道 2 8 , 2 9 , 使管道 2 8 、 2 9 作开启及关闭的动作， 亦使高压气体顺序定时地进入动力缸 6 2 内。
图 3 、 图 4 、 图 5 是分别由图 2 中三只压缩机截面线 D - D、 E - E、 F - F 引出。 图 3 与图 5 的构造完全相同， 壳体即外壳 1 0 上凿有进气孔。 图 4 为动力缸的截面图， 在壳体上凿有一个排气 孔及装置有一火花塞 7 1 。 图 1 4 是图 1 5 中圆圏部分局部故大 图， 表示气体由压缩缸 6 1 至动力缸 6 2 的管道 2 8 及刀沟 1 8 。 图 1 5 为表示整台内燃机中的气体部分 （内燃机分为机体及气体两 部分， 本图为取走机体部分留下气体部分） ， 仔细观看气体部分， 很容易了解其流程及动作。 图中， 6 1 及 6 3 为压缩缸， 6 2 为动力缸、 2 7 、 3 0 为进 气孔， 0 为^ 气孔， 1 8 、 1 9 为刀 7¾ , 2 8 、 2 9 为营迢。
气体在机内流动方向是这样的， 可分为混合气部分及纯空气部 分， 混合气部分： 其中的混合气是由进气孔 2 7 进入压缩缸 6 1 后， 经过压缩后， 再经管道 2 8 , 由刀沟内的气刀 3 7 控制， 再进 入动力缸 6 2 ， 然后被点燃引爆， 产生动力， 推进内燃机； 纯空气 部分： 纯空气由进气孔 3 0 被吸入压缩缸 6 3 , 同样的动作经过压 缩后， 再由管道 2 9 进入正在燃烧中的动力缸 6 2 。 其目的是为助 燃正在燃烧中的气体， 使其达到静化废气的效果。 此过程与活塞引 擎涡轮增压器不同， 涡轮增压器是将空气 （利用废气压力转动叶 片） 打入进气管道内， 其动作为一次压缩一次爆炸， 而其供应气体 时间为在点火爆炸之前。 本发明气体供应时间为点火燃烧之后的二 次空气结构设计， 具有协助燃烧及减少振动力两大效果， 图 1 6 为 主轴、 偏心体组、 机体三者的关系位置透视立体图。 图 1 7 至图 2 0 的四个图将内燃机体部分切开并移动或转动 9 0 度， 以利于观察 及了解其结构。 图 1 8 为偏心体组切开的部分， 压缩缸 6 1 、 6 3 的偏心体 1 4 、 1 6 上附有气刀 3 7 , 3 8 , 动力缸 6 2 的偏心体 1 5 无气刀装置， 三个偏心体 1 4 、 1 5 、 1 6 结合为一体称为偏 心体组， 各偏心体 1 4 、 1 5 、 1 6 共用同一轴心， 各自可保持转 动自如。 如图 1 7 所示， 装配时， 两侧的偏心体 1 4 , 1 6 端及气 刀 3 7 、 3 8 分别装置于两侧壳盖 1 3 内的搰沟 2 2 及机体内的气 体刀沟 1 8 、 1 9 内。 图 1 9 及图 2 0 为图 1 7 中圆圈部分局部放 大图， 前者显示偏心体組的截面， 偏心体的接触面有凹凸沟， 凹凸 沟可使其保持在凹凸沟内搰行转动稳定。 后者表示刀沟 1 8 、 1 9 , 其用途为支撑气刀 3 7 , 3 8 , 使刀面可在刀沟内滑行并切割 管道 2 8 , 2 9 ,达到使气体转换，即关闭、 开启至动力缸的效果。
婧参阅图 6 至图 9 的正视图， 为了便于了解， i靑同时参阅图 1 0 至图 1 3 的俯视图所示， 此四图为与图 6 至图 9 相对应的俯视 图， 其均显示出本发明的运转动作的流程， 兹说明如下： 图 6 左半 部为压缩缸 6 1 , 压缩混合气； 右半部为动力缸 6 2 , 产生动力， 图中构件由内至外分别为： 压缩杆 3 4 , 3 6 , 其压缩气体； 动力 压缩杆 3 5 , 其产生动力； 导体 2 4 , 2 5 , 2 6 , 其密闭气体； 气刀 3 7 , 3 8 , 其在刀沟内切割管道； 气体压缩缸 6 1 , 6 3 , 其容纳高压气体； 气体动力气缸 6 2 , 其容纳燃烧气体； 压缩缸外 売 1 0 、 1 0 - 2 ； 动力缸外壳 1 0 - 1 ； 火 ¾塞7 1 , 其产生火 花点燃气体； 管道 2 8 , 2 9 , 其为压缩缸 6 1 , 6 3 至动力缸 6 2 的通道。 各图所示的动作如箭头正转方向， 由图 6 顺序运动至图 9 ， 图右侧附加的小图代表未燃烧的高压气体 6 1 ' , 6 3 ' ( 左） 或已爆炸的燃烧气体 6 2 ' (右） ， 高压气体 6 3 ' (纯空 气） 与动力缸 6 2 在图 8 相接触， 此时表示供应纯空气正开始， 转 至图 9 时表示供应纯空气动作过程完毕， 压缩缸 6 3 容积空间消 失。 图 6 中混合气体被压缩成压缩缸 6 1 形状时压缩比约 1 0 ： 1 , 为气体转换开始点， 附于偏心体上的气刀 3 7 的缺口正通过管 道 2 8 ， 使管道畅通 （开启动作） ， 混合气体开始经此管道 2 8 被 压入右侧的动力缸 6 2 内， 当转动至图 7 时， 气刀 3 7 的缺口另一 端再次通过管道 2 8 成关闭动作， 此时压缩缸 6 1 的容积空间消 失， 其内的高压气体 6 1 ' 即高压混合气体全部进入右侧的动力缸 6 2 内， 再经转动若干角度， 火花塞 7 1 适时点燃混合气体， 体积 膨胀， 产生动力推动动力压缩杆 3 5 进而转动内燃机。 当再转动至 图 8 时， 压缩杆 3 6 将纯空气压缩成压缩缸 6 3 状， 其形状与压缩 缸 6 1 相同， 此时气刀 3 8 上的缺口正通过管道 2 9 ， 纯空气供应 开始， 高压气体 6 3 ， 即高压纯空气开始经此管道进入动力缸 6 2 内， 以协助燃烧的正在爆炸具有动力燃烧气体 6 2 ' , 使其燃烧得 更彻底更干净。 此二次燃烧装置为本发明设计的特点之一， 继续再 转动至图 9 时， 气刀 3 8 的缺口通过管道 2 9 关闭管道， 压缩缸 6 3 的容积空间消失， 纯空气供应动作完毕， 右侧动力缸 6 2 的容积 因膨胀气体及二次新鲜空气的加入而增大， 动力缸 6 2 内的气体燃 烧过程更干净完全。 再转动回到图 6 时， 则完成了进气、 压缩、 爆 炸、 排气四个内燃机的基本动作。
实际上， 本发明是由三只简单型构造几乎相同的空气压缩机所 构成， 两侧的压缩机其一为压缩混合气， 另一为压缩纯空气， 中间 压缩机因具有产生动力及排除废气的功能而称为动力机， 其气缸称 为动力缸， 动力缸因气体燃烧及产生动力而永远处于较高温度， 此 处可加大冷却面积的设计， 又因其不负担压缩冷空气周围温度变化 小， 其材质寿命较长； 在压缩机数量上若除去第三只压缩机 （即 C 压缩机） ， 则成为无二次空气的内燃机。 此机型燃烧过程与活塞引 擎相同。 不管是由单只、 双只或三只压缩机所組成的机体， 皆可做 为^气 ϋ缩 L的用迩， 茬冉苻机侔分为可动组及不 动 则可动 组包括主轴组即三压缩杆、 一主轴、 二轴承， 及偏心体组即三偏心 体、 二气刀、 三导体， 不可动组包括外壳机体及两机壳盖， 机体内 有管道、 刀沟、 进排气孔及火花塞， 机壳盖内设有支撑偏心体用的 滑沟， 支撢轴承用的轴承座， 再以转动轴心区分成两轴心， 主轴组 与外壳共用一中心轴心， 偏心体组用偏心轴心， 转动时， 三偏心体 各自转动的迷度不同。
另外， 若将偏心体上的气刀缺口设计变申， 转动时， 管道因刀 面缺口延缓通过而延迟打开， 致使压缩缸内气压升高 （压缩比约 1 5 : 1 ) , 待气体转入动力缸内， 因压力变化不多， 使用喷油嘴代 替火花塞而喷以燃料， 其效果如同鄂图引擎的喷射装置 （如柴油引 鼙） 。 另本发明中能变更气刀刀面的缺口， 并能提髙气体压力， 以 喷油嘴代替火花塞而成为喷射引辇。 本发明中， 因下列系统为非本 申婧主题技术方案的范围之内， 且与动作流程无直接关系， 故在此 并未详加说明， 这些系统包括冷却、 润搰、 电路、 燃料、 密闭、 平 衡等传统部件结构的设计。 经由以上所述， 应能完全明白本发明的 结构与特性， 其确为一种不同于已往的全新设计。
值得指出的是， 以上有关本发明的详细说明与附图， 仅为清楚 说明本发明的实施例， 并进一步理解本发明的技术方案， 而并非用 来限制本发明， 凡是依据本发明技术方案所做的等效变换均仍应包 括在本发明技术方案的范围内。 工业应用性
