摘要： In an aspirating spray head, fluid is introduced by way of an air inlet passage through one end of a larger diameter receiving passage which is open at its other end and liquid is introduced to the receiving passage by way of a liquid inlet passage which laterally opens into the receiving passage between its end. The end of the receiving passage through which the air inlet passage opens is defined by an abrupt shoulder which lies in a plane perpendicular to the receiving and air inlet passages, and the edge of the openings through which the air and liquid inlet passages open into the receiving passages are spaced from each other. When air is introduced into the receiving passage from the air inlet passage, liquid is aspirated through the liquid inlet passage and mized with the air in the receiving passage where the mixture is discharged therefrom as a spray. The ratio of the diameter of the receiving passage to the diameter of the air inlet passage is preferably between approximately 1.6 and 2.5 and the ratio of the distance between the openings of the liquid and air inlet passages to the diameter of the air inlet passage is preferably less than approximately 2.0.
摘要翻译：在抽吸喷头中，流体通过空气入口通道，其通过在其另一端开口的较大直径的接收通道的一端，并且液体通过液体入口通道被引入到接收通道，该液体入口通道横向打开进入接收通道之间。空气入口通道打开的接收通道的端部由位于垂直于接收和空气入口通道的平面中的突然的肩部以及空气和液体入口通道穿过的开口的边缘限定接收通道彼此间隔开。当空气从空气入口通道引入接收通道时，液体通过液体入口通道被吸入并且与接收通道中的空气配合，其中混合物作为喷雾从其排出。接收通道的直径与空气入口通道的直径的比率优选在大约1.6和2.5之间，并且液体和空气入口通道的开口之间的距离与进气通道的直径的比率优选为小于约2.0。

摘要： A nozzle for discharging a swirling atomized fluid includes a vortex chamber defined in the nozzle body, a gas inlet tangentially communicating with the chamber and a liquid inlet axially communicating with the chamber wherein the liquid is mixed with the swirling gas in the chamber. An impingement member is positioned in the path of fluid flowing from the chamber having a primary impact surface in the chamber upon which the swirling mixture impinges and a secondary impact surface adjacent to, but spaced from, the nozzle discharge opening upon which the swirling mixture also impinges as it is being discharged from the nozzle.
摘要翻译：用于排出旋转雾化流体的喷嘴包括限定在喷嘴体中的涡流室，与腔室切向连通的气体入口和与腔室轴向连通的液体入口，其中液体与腔室中的旋转气体混合。冲击构件定位在从具有初始冲击表面的腔中流动的流体的路径中，旋转混合物在其中撞击的腔室中，以及邻近旋转混合物的喷嘴排出口邻近但间隔开的次级冲击表面当它从喷嘴排出时撞击。

摘要： In a spiral swirl chamber nozzle, the spray orifice and axial origin of the spiral of the spiral swirl chamber are eccentrically offset from each other in a sector of the swirl chamber between approximately 90* to 150* from the maximum radius of the spiral adjacent the fluid inlet and in the direction of fluid rotation in the chamber and by a distance of approximately 0.005 to 0.015 inch.

摘要： A leaf spring nozzle flow control which is positioned in the nozzle body controls the flow of fluid to a fixed restriction nozzle such that the flow varies substantially in direct linear relationship with the pressure of the fluid. The flow control includes a plate having a plurality of leaf spring valves which are biased by the fluid pressure from a first position in which flow to the nozzle is blocked to a second position in which the fluid flows to the nozzle when the pressure of the fluid exceeds a predetermined minimum magnitude as determined by the leaf spring.

摘要： A SELF-PURGING REGENERATIVE TURBINE PUMP SO CONSTRUCTED THAT INTERNAL CLEARANCE SPACES AND CAVITIES ARE CONTINUOUSLY PURGED DURING OPERATION OF THE PUMP, THEREBY PERMITTING THE PUMPING OF CONTAMINATED LIQUIDS. CLEARANCE SPACES BETWEEN THE ENDS OF THE IMPELLER AND THE ADJACENT SURFACES OF THE HOUSING, AND BETWEEN THE PERIPHERY OF THE IMPELLER AND THE STRIPPER WALL OF THE HOUSING ARE SLIGHTLY THICKER THAN THE SIZE OF CONTAMINANTS ENTRAINED IN THE LIQUID BEING PUMPED. THE FIRST-MENTIONED SPACES COMMUNICATE WITH A SEAL CAVITY, AND THE SEAL CAVITY HAS MEANS OF THE FREE HYDRAULIC COMMUNICATION WITH THE INLET OF THE PUMP TO INSURE A CONTINUOUS FLOW OF PURGING LIQUID AS LONG AS THE PUMP IS IN OPERATION.
