    • 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.

    • The gas driven oscillator 10 employs as its main part an engine 11 having a casing 12 and a pair of expansion chambers 13 and 14 on either side of a floating piston 15 adapted to reciprocate within the cylinder 12. The piston is mounted on a piston rod 16 extending through the cylinder 12 and into a compressor 17, the compressor 17 having a cylinder 18 and a piston 19 mounted on the piston rod 16 to move in concert with the piston 15. An air storage tank 20 holds compressed air typically at a pressure between 100psi to 300psi. The compressed air in tank 20 can be generated using a compressor located upstream. The upstream compressor can be driven by any suitable means including electric motor, internal combustion engine, windmill or the like. A valve 21 downstream of the tank 20 controls delivery of the compressed air from the tank 20 to the engine 11 via a pair of valves 22 and 23 with the valves 22 and 23 being mounted on an adjustment screw and slidably disposed on the piston rod 16. The spacing between the valves 22 and 23 can be adjusted in order to vary the amplitude of the piston 15 within the cylinder 12. The valves can be moved in opposite directions and an equal amount. The piston rod 16 includes spaced slots 24 and 25 which alternately align with passages inside the respective valves 22 and 23 to deliver a pulse of compressed air from the tank 20 to the respective chambers of the cylinder 12 at each movement of alignment. The piston 15 oscillates according to an amplitude set by the spacing between the valves 22 and 23. The valves 22 and 23 are mounted on the adjuster screw 26 so they can be moved together or apart as desired.
    • 气体驱动振荡器10使用发动机11作为其主要部分,发动机11具有壳体12和在适于在气缸12内往复运动的浮动活塞15的任一侧上的一对膨胀室13和14.活塞安装在活塞杆 16延伸穿过气缸12并进入压缩机17,压缩机17具有气缸18和安装在活塞杆16上的活塞19,以与活塞15一致地移动。储气罐20通常保持压缩空气的压力 在100psi到300psi之间。 罐20中的压缩空气可以使用位于上游的压缩机产生。 上游压缩机可以由任何合适的装置驱动,包括电动机,内燃机,风车等。 在罐20下游的阀21控制经由一对阀22和23从罐20向发动机11输送压缩空气,其中阀22和23安装在调节螺钉上并且可滑动地设置在活塞杆16上 可以调节阀22和23之间的间距,以便改变气缸12内的活塞15的振幅。阀可以以相反的方向和相等的量移动。 活塞杆16包括间隔开的槽24和25,它们与各个阀22和23内的通道交替对齐,以在每次对准移动时将来自箱20的压缩空气脉冲输送到气缸12的相应腔室。 活塞15根据由阀22和23之间的间隔设定的幅度摆动。阀22和23安装在调节螺钉26上,以便它们可以根据需要一起移动或分开。
