    • The specification discloses a rotary gas pressure engine system including a housing and a stationary shaft extending through the housing. A circular cylinder block is rotatably mounted on the stationary shaft. The cylinder block includes a plurality of radial piston cylinders and a piston mounted within each cylinder for slidable movement therein. The cylinder block further includes a circumferentially mounted cam ring having generally elliptical risers around its inner periphery in order to cause radial operation of the pistons. A vane pump is associated with the cylinder block for pumping fluid from a fluid reservoir external of the housing and through the housing to a vaporization chamber external of the housing.
    • 本说明书公开了一种旋转气体压力发动机系统,其包括壳体和延伸穿过壳体的固定轴。 圆筒体可旋转地安装在固定轴上。 气缸体包括多个径向活塞气缸和安装在每个气缸内的活塞,用于在其中滑动。 气缸体还包括周向安装的凸轮环,其环绕其内周围具有大致椭圆形的立管,以便引起活塞的径向操作。 叶片泵与气缸体相关联,用于将流体从壳体外部的流体容器泵送并通过壳体到壳体外部的蒸发室。
