 本发明的实施方式
下面结合附图与具体实施方式对本发明作进一步详细的说明：
实施例一、一种压缩气体发动机，如图1-6所示，包括叶轮室10和叶轮20。叶轮室10上对称开设有三组进气口、三组 喷气导入槽、 三组排气口 和三组排气导出槽 13 。
每一组进气口包括四排，每排进气口有五个，共计20个进气口12，沿叶轮室10的厚度方向排列，各进气口12与叶轮室10的周面切线方向之间具有相同的倾斜角度α，倾斜角度α 小于90度， 以便使喷入的气体能够有效作用于叶轮20端部的叶齿21上，推动叶轮20转动。在 叶轮室 10 的内表面上开设有 三组 喷气导入槽，每 组 喷气导入槽包括五个各自独立的喷气导入槽 11 ，图2所示是 五个各自独立的喷气导入槽 11 处于展开状态时的结构示意图。 图4所示是叶轮室10上的 喷气导入槽 11 的横向截面 结构放大示意图。 图 1 给出了处于相同厚度位置时的 叶轮室10的四个进气口12与 对应的喷气导入槽 11 连通 的结构示意图 。 喷气导入槽 11 的跨度大于两个相邻叶齿之间的距离。 叶轮室10上开设的排气口14与叶轮室10的周面切线方向之间的夹角 β 小于90度。其中，每一组排气口由9*10个具有相同倾斜角度 β 的排气口14组成。为了能够顺畅地进行 排气，在叶轮室 10 的内表面上开设与 叶轮室10的中心 轴线平行的排气导出槽 13 ，每一组 排气口对应开设一个 排气导出槽 13 ，每组的各排气口 14 与排气导出槽 13 相通，排气导出槽 13 的宽度与叶轮 20 的宽度基本相一致。喷气导入槽 11 末端与相邻的排气导出槽 13 之间的最短距离大于两个相邻叶齿之间的距离。
叶轮20的周面上具有复数个等分设置的叶齿21和位于叶齿21两侧的侧板23，叶轮20的周面上的叶齿21与叶齿之间的两侧侧板23构成复数个 工作腔 22 ， 装设叶轮20的叶轮室10 的内表面与各工作腔 22 构成能够相对密封从 压缩气体喷入孔12 喷入气体的复数个气室，当 暂存有压缩气体的 工作腔 22 转动到 缩气体排出孔14所在的位置时， 工作腔 22 内的压缩气体经 压缩气体排出孔14向外喷射 作功，进一步推动叶轮 20 动转。 排气口14的倾斜角度 β 应能够使当压缩气体从排气口14释放时能够更有效地反作用于叶齿21作功，进一步推动叶轮输出动力。
实施例二、一种压缩气体发动机，如图7和8所示，包括叶轮室100和装设于叶轮室100内的叶轮200。叶轮室100上对称开设有三组进气口、三个 喷气导入槽 104 、 三个排气口103 和三组排气导出槽 103 。
为了提高动力性能，使喷入的压缩气体集中、有效作用于叶轮 200 的叶齿端部所希望的叶面位置，在叶轮室 100 的内表面上开设有沿转动周面设置的、与 进气口101相通的 喷气导入槽 104 ，每一组进气口 101 都接入对应设置的喷气导入槽 104 内。 接近 进气口 101 时的喷气导入槽 104 深而宽，远离进气口 101 时的喷气导入槽 104 浅而窄（图 7 ），喷气导入槽 104 的长度大于两个相邻叶齿 203 之间的距离 L ，使得从喷气导入槽 104 导出的压缩 气体 一是能够同时作用于二个或两个以上的叶齿 203 上，二是能够按照预设的导出路径作用在希望的叶齿部位，以产生更强的推力。
在叶轮室 100 的内表面上开设有与转轴轴线平行的 排气导出槽 103 ，排气导出槽 103 与排气口 102 相通。为了更好的排气，排气导出槽 103 的宽度与叶轮 200 的厚度基本相一致。
为了防止漏气，避免 刚喷入的气体直接从排气导出槽 103 排出 ， 喷气导入槽 104 末端与最近的排气导出槽 103 之间的距离应大于两个相邻叶齿之间的距离 L 。
叶轮200的周面上具有复数个等分设置的叶齿203和位于叶齿203两侧的侧板201，叶轮200的周面上的叶齿203与叶齿之间的两侧侧板201构成复数个 工作腔 202 ， 装设叶轮200的叶轮室100 的内表面与各工作腔 202 构成能够相对密封从 压缩气体喷入孔101 喷入气体的复数个气室，当 暂存有压缩气体的 工作腔 202 转动到压 缩气体的 排气导出槽 103 所在的位置时， 工作腔 202 内的压缩气体经 排出孔101向外释放压缩气体 作功，进一步推动叶轮 200 动转。
在本实施例中，压缩气体优选压缩空气。当然，根据需要，也可以是其它压缩气体。
以上内容是结合具体的实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
