摘要： Controls for operating fluid pressure fueled reciprocating piston engines are simplified by passing fuel directly to a cylinder inlet port from a synchronously timed rotary distributor. This permits a snap acting diaphragm transfer valve normally opening the inlet fuel path to the cylinder to respond to a decrease in fuel pressure to quickly snap open an exhaust port and close the inlet port. Several embodiments include a battery operated fuel supply source, recycling of spent fuel, and auxiliary exhaust paths from bottom dead center cylinder positions, to increase efficiency, speed and reliability.

摘要： A radial piston and cylinder compressed gas motor is disclosed which is particularly suited for use where economical power sources are required. The motor includes a cylinder block having a plurality of radially extending cylinders open at their outer ends to radially extending passages and having exhaust ports open when associated pistons are adjacent their bottom dead center positions. Such passages extend to a valve system provided on the crank of the motor which functions to supply compressed gas to selected cylinders while connecting other cylinders together so that gas is exhausted from cylinders containing extending pistons to open exhaust ports in other cylinders. This minimizes back pressure to resist motor operation. The crank is formed of two generally cylindrical members and can be produced without eccentric machining or grinding operations. A simple cylindrical head gasket, which is compressed against the periphery of the cylinder block, closes the cylinders and is held in place by a shrink-fitted ring. Peripherally extending inclined slots are formed in the cylinder wall for exhausting gas from the motor into a circular manifold chamber through which the gas is exhausted from the motor. The manifold chamber is provided with enlarged portions adjacent to each exhaust port which reduce exhaust noise. Some embodiments provide motors without master piston rods. Such embodiments provide wrist plates connected to offset piston rods to provide improved starting and running torque.
摘要翻译：公开了一种径向活塞和气缸压缩气体电动机，其特别适用于需要经济电源的场合。马达包括一个气缸体，其具有多个径向延伸的气缸，在其外端开放到径向延伸通道，并且当相关的活塞邻近其下止点位置时，排气口打开。这种通道延伸到设置在马达的曲柄上的阀系统，其功能是将压缩气体供应到选定的气缸，同时将其它气缸连接在一起，使得气体从包含延伸活塞的气缸排出到其它气缸中的排气口。这最大限度地减少了抵抗电机运行的背压。曲柄由两个通常为圆柱形的构件形成，并且可以在没有偏心加工或研磨操作的情况下制造。一个简单的圆柱形头垫片被压靠在气缸体的周边上，使气缸闭合，并通过一个收缩环保持在适当位置。在气缸壁中形成有外围延伸的倾斜槽，用于将气体从电动机排出到圆形歧管室中，气体通过该歧管室从电动机排出。歧管室设置有与每个排气口相邻的放大部分，其减少排气噪声。一些实施例提供没有主活塞杆的电动机。这样的实施例提供连接到偏移活塞杆的腕板，以提供改进的启动和运行扭矩。

摘要： A uniflow engine has a plurality of cylinders disposed symmetrically around a common crankshaft connected to pistons reciprocating in the cylinders. In response to the availability of a working fluid vapor at a predetermined condition, such as a high pressure or temperature, incoming vapor is supplied to those cylinders in which the respective pistons are in their working strokes to thereby initiate rotation of the crankshaft in a predetermined direction regardless of the position in which the crankshaft had stopped last. Once rotation is initiated and a predetermined mode change speed attained in a "start-up mode" by engine operation from start, vapor inlet valves are controlled to change engine operation over to a "running mode". In the "start-up mode" incoming vapor is admitted over a substantial portion of the piston working stroke, whereas in the "running mode" vapor inflow is terminated relatively early in the working stroke so that a vapor change does work in expandiing against the piston.

摘要： A piston of a gas engine is reciprocatingly guided in a cylinder. A gas inlet valve whose valve closure component consists of a ball is situated in the cylinder head. The ball is pushed open in the top dead-center position of the piston by a protrusion formed on the upper portion of the piston in order to admit propellant gas into an expansion chamber formed by the cylinder. The gas engine must be set into operation by turning a crankshaft. If the piston accidentally lies near top dead-center when starting, the piston must be moved against full gas pressure. In order to alleviate starting, a shut-off device is provided which has a start position and an operational position. The shut-off device connects the inlet side of the gas inlet valve with an air conduit opening into ambient air and obturates a pressurized gas container in the start position. The shut-off device obturates the air conduit and clears a gas supply conduit leading from the pressurized gas container to the inlet side of the gas inlet valve in the operational position. With the help of this shut-off device, it is possible to start even gas motors equipped with gear-reduction transmissions.
摘要翻译：燃气发动机的活塞在气缸中往复导向。阀门关闭部件由球体组成的进气阀位于气缸盖中。球通过形成在活塞上部的突起在活塞的上止点位置推开，以便将推进剂气体引入由气缸形成的膨胀室中。燃气发动机必须通过转动曲轴进行操作。如果在起动时活塞意外地靠近上止点，则活塞必须全压移动。为了减轻启动，提供了具有起始位置和操作位置的切断装置。关闭装置将进气阀的入口侧与通向环境空气的空气管道连通，并将起始位置的加压气体容器堵塞。截止装置堵塞空气管道，并将从加压气体容器导出的气体供给导管从工作位置清除到进气口的入口侧。借助该关闭装置，可以启动配有齿轮减速传动装置的气动马达。

摘要： An improvement in a reciprocating engine used in an energy recovery system wherein the inlet valves to the cylinders of the engine are operated by independently time adjustable actuating means.The system for recovering energy from a pressured reactor comprising a reactor, a reciprocating engine connected to the reactor to receive reaction effluent from said reactor thereby driving the pistons of the reciprocating engine by expansion of the effluent and recovery apparatus downstream of the engine for recovering products from the effluent.The expanding reactor effluent is used to drive the pistons which are especially valved in conjunction with the effluent inlet port in the cylinder to facilitate handling the effluents to adjust the flow into an expansion chamber to obtain maximum recovery, the pistons in turn operate a crankshaft through a crosshead which may power compressors or operate a generator to produce electricity. It is reasonable to expect recovery in a directly usable form, such as electricity, of over 60% of the energy theoretically available in the pressured reactor effluent in some cases.

摘要： A longitudinally slidable cam shaft means for use with an automotive power system having improved efficiency and low pollution characteristics. The drive motor operates only when power to the wheels is desired and includes variably opening valves controlled by the cam shaft means. The axially sliding cam shaft controls the valves which may be opened by varying amounts to control the speed and direction of rotation of the drive motor. Regenerative braking is provided by the drive motor and by reversing the direction of rotation of the cam shaft, the valves act to send compressed gas to the combustion chamber.
