    摘要： A spool-type valve system for use with a high-speed filling machine, in which a solenoid valve controlled by the main shaft of the filling machine, selectively supplies air under pressure to a respective end of a pneumatically operated piston-cylinder unit of a spool valve assembly which selectively opens and closes the pump space with respect to the reservoir for the product to be filled while simultaneously closing and opening the pump space with respect to the discharge nozzle.

    摘要： This hydraulic engine utilizes two sets of hydraulic cylinders connected to a shaft so as to be alternately pressurized as the shaft is reciprocally driven by a pair of conventional internal combustion chambers. The outlets of all hydraulic cylinders are connected to a common output line via valves. During each power stroke certain of the hydraulic cylinders being pressurized are selectively disconnected (depressurized) from the output line. This effectively decreases the load on the driving chamber, and insures a relatively constant, high pressure hydraulic fluid output level despite changes in supplied force during each power stroke. The selective cylinder disconnection may be implemented programmatically in response to changes in engine parameters such as combustion chamber pressure. The engine also includes a pump for supplying input hydraulic fluid to each set of cylinders while that set is not being pressurized. The input fluid force is additive to the power supplied by the operative combustion chamber. The pump is driven by pressurized fluid from the output line, and includes a flywheel with sufficient inertia to maintain pumping, and hence continue engine operation, in the event of a misfire in one of the combustion chambers.

    摘要翻译： 该液压发动机利用连接到轴的两组液压缸，以便当轴由一对常规内燃室往复驱动时交替地加压。 所有液压缸的出口通过阀门连接到公共输出管路。 在每次动力冲程期间，加压的某些液压缸从输出线路选择性地断开（减压）。 这有效地降低了驱动室中的负载，并且尽管在每个动力冲程期间的供给力发生变化，也确保了相对恒定的高压液压流体输出水平。 响应于诸如燃烧室压力的发动机参数的变化，可以以编程方式实施选择性气缸断开。 该发动机还包括一泵，用于在每一组气缸上提供输入液压油，同时该组不被加压。 输入流体力与由操作燃烧室供给的动力相加。 该泵由来自输出管线的加压流体驱动，并且包括在其中一个燃烧室中发生失火的情况下具有足够的惯性以维持泵送并因此继续发动机运转的飞轮。

    摘要： A slide valve for dense or viscous materials, e.g. concrete, has a slide element connected to a piston rod which extends out of the valve housing through a seal and carries a piston received in a cylinder which is clamped to the housing around the seal by a clamping nut. The cylinder has an outer actuation chamber while an inner annular chamber between the piston and the seal is a flushing compartment connected to a reservoir of liquid through a single duct. As the piston moves toward the seal, the liquid in the flushing compartment is expelled, taking with it any foreign matter which has gotten past the seal, and as the piston movement is reversed this compartment is filled with the liquid via this duct to flush the rod again. The valve element, valve guides, end stops, and sleeves surrounding the piston rods are all easily removable and replaceable to facilitate servicing of the valve.
