    • A high efficiency steam engine or gas compressed motor with improved intake and exhaust flow provided by separate pairs of intake (13, 17) and exhaust (14, 16) ports or passages located at both ends of a steam drive cylinder (1) containing a piston (3).In a central section of the cylinder (1) is uniflow or central exhaust steam ports (15). A valve cylinder containing an improved slide valve (5) located adjacent to the drive cylinder provides for timed sealing of intake and exhaust ports during operation. Exhaust is facilitated by the provision of two paths of exhaust from the cylinder and the exhaust ports may be adjusted for a flow volume to meter exhaust steam flow to significantly reduce back pressure only at low speeds of engine.
    • 一种高效率的蒸汽发动机或气体压缩马达,其具有改进的进气和排气流量,分别由位于蒸汽驱动气缸(1)两端的进气口(13,17)和排气口(14,16) 活塞(3)。在气缸(1)的中心部分是单流或中央排气蒸汽口(15)。 包含位于驱动气缸附近的改进的滑阀(5)的阀筒提供了操作期间进气和排气口的定时密封。 通过提供来自气缸的两个排气路径来排放排气,并且可以调节排气口的流量以计量排气蒸汽流量,以便仅在低速发动机下显着降低背压。
