Abstract: A full coverage fluidic oscillator (2) includes a fluidic circuit member preferably having an oscillation inducing internal chamber, at least one inlet (8) or source of fluid under pressure, at least a pair of output nozzles (14, 16) connected to the source of fluid for projecting at least first and second impinging fluid jets into free space, where the first and second impinging jets collide or impinge upon one another at a selected jet angle to generate a substantially omni-directional sheet jet having selected thickness. The first and second jets are aimed at a pre-selected intersection point in free space where impingement is to occur. The sheet jet's thickness Δy is determined by the time-varying path or oscillation of each of the first and second impinging jets. The first and second impinging jets can be made to oscillate or pulsate by use of vortex generating amplifier structures (68, 70, 72, 149) within the internal chamber's fluid flow paths.

Abstract translation: 全覆盖流体振荡器（2）包括流体回路构件，其优选地具有振荡诱导内室，至少一个入口（8）或压力下的流体源，至少一对输出喷嘴（14,16），其连接到 用于将至少第一和第二冲击流体射流投射到自由空间中的流体源，其中第一和第二冲击射流以选定的射流角度彼此碰撞或撞击，以产生具有选定厚度的基本上全方位的片射流。 第一和第二射流瞄准在自由空间中预先选择的交叉点，以便发生冲击。 片材射流的厚度Δy由第一和第二冲击射流中的每一个的时变路径或振荡决定。 第一和第二冲击射流可以通过使用在内腔的流体流动路径内的涡流产生放大器结构（68,70,72,149）进行摆动或脉动。
