    • PROBLEM TO BE SOLVED: To provide a high efficiency steam engine or gas compressed motor with improved intake and exhaust flow provided by separate pairs of intake and exhaust ports or passages located at both ends of a steam drive cylinder containing a piston.SOLUTION: The central section of the cylinder 1 is uniflow or central exhaust steam ports 15. A valve cylinder 2 containing an improved slide valve 5 located adjacent to the drive cylinder 1 provides for timed sealing of intake ports 13, 17 and exhaust ports 14, 16 during operation. Exhaust is facilitated by the provision of two exhaust paths 14, 16 from the cylinder 2 and the exhaust ports 14, 16 may be adjusted for a flow volume to meter exhaust steam flow to significantly reduce back pressure only at low speeds of engine.
    • 要解决的问题:提供一种高效率的蒸汽发动机或气体压缩马达,其具有由位于包含活塞的蒸汽驱动圆柱体的两端的单独进气和排气口对或通道提供的改进的进气和排气流。 气缸1的中央部分是单流或中央排气蒸汽口15.包含位于驱动气缸1附近的改进的滑阀5的气缸2提供进气口13,17和排气口的定时密封 端口14,16在运行。 通过从气缸2设置两个排气通道14,16,排气可以被调节,并且排气口14,16可以调整流量来计量排气蒸汽流量,以便仅在发动机的低速下显着降低背压。 版权所有(C)2012,JPO&INPIT
