Abstract: Apparatus for forming pulsed jets of liquid. A movable cylinder cooperates with a nozzle block to define a compressible charge chamber into which water, or other liquid flows. A latch retains the cylinder. When it is desired to generate a pulse, the latch is released, allowing the cylinder to move and expand the charge chamber, thereby drawing from the nozzle any liquid remaining from the preceding pulsed jet of liquid. A piston is then actuated to impact on the cylinder, compressing the chamber and expelling the charge through the nozzle as a pulsed liquid jet. The cylinder is moved so that the charge chamber is compressed and the latch again retains the device in this condition. A floating check valve permits escape of air from the chamber during filling with water.

Abstract: Apparatus for producing a high velocity jet pulse of liquid suitable for cutting or fracturing such materials as rock, metal, concrete and wood. A barrel is provided with a bore that intersects a rotatable valve which in a first position receives a liquid or gel charge and which in a second position is colinear with the barrel bore. Compressed gas expells the charge from the barrel through a nozzle to form a pulsed jet of liquid. Means can be provided for positioning the nozzle adjacent an extrusion as it issues from an extruder, permitting on-line cutting of the extrusion and for rotating the nozzle about a horizontal axis to permit operation at the optimum angle of cut.

Abstract: Apparatus for forming pulsed jets of liquid. A pressure cylinder cooperates with a barrel inlet end to define a charge chamber. With the pressure cylinder in its normal position, the barrel inlet opening is blocked. Upon actuation of the device, the pressure cylinder is forced toward the barrel inlet end, applying pressure to charge material within the charge chamber, until the barrel outlet opening is unblocked and the pressurized charge material is expelled through the barrel as a pulsed jet.

Abstract: Apparatus for forming pulsed jets of liquid at relatively low pressures and capable of expelling the pulsed jets over moderate distances for use as a riot control device. A compressed gas is passed to a chamber having liquid therein so that upon actuation of a quick opening valve the liquid is forced from the chamber, through an acceleration tube and out a nozzle. The quick opening valve might be positioned between the pressurized gas source and the liquid chamber, or it might be in the acceleration tube. The gas can act directly on the liquid or it can act through a piston.

Abstract: Apparatus for generating pulsed jets of liquid or gel charge material. An expulsion barrel has a charge inlet, a charge storage area, a charge outlet and a valve zone coupling the charge storage area with the charge inlet and the charge outlet. A valve within the valve zone moves under pressure from the charge inlet to a position in which charge material is permitted to pass from the inlet to the charge storage area, while being blocked from the charge outlet, and under pressure from the charge storage area due to action of a piston to a position in which charge material is permitted to pass from the storage area to the charge outlet, while being blocked from the charge inlet. In this manner, the expulsion barrel is dry between jets which provides for a higher pressure jet. A improved seal prevents charge material from escaping around the piston. The seal includes a non-resilient portion interfacing with the piston during piston movement and a resilient portion placed between this non-resilient portion and the surrounding housing and which is compressed due to applied pressure from the charge material to seal the non-resilient portion and the piston thereby assuring a leak-proof seal.
Abstract translation: 用于产生液体或凝胶电荷材料的脉冲射流的装置。 排出桶具有充电入口，电荷存储区域，充电口和将电荷存储区域与充电入口和充电口连接的阀区。 阀区内的阀门在压力下从充电入口移动到允许充电材料从入口到电荷存储区域的位置，同时从充电插座阻塞，并在来自电荷存储区域的压力下 使得活塞到充电材料被允许从存储区域传递到充电出口的位置的作用，同时被阻止从充电入口。 以这种方式，在提供较高压力射流的射流之间，排出筒是干燥的。 改进的密封件防止充电材料在活塞周围逸出。 密封件包括在活塞运动期间与活塞接合的非弹性部分和设置在该非弹性部分和周围壳体之间的弹性部分，并且由于来自加料材料的施加的压力而被压缩以密封非弹性部分， 从而确保了防漏密封。
