    • A compact catcher assembly (20) for an abrasive waterjet having a nozzle assembly (22) and a jewel orifice (not shown) for producing a high velocity fluid jet (26) to cut a workpiece within a small area in which to receive the catcher assembly, such as between the upper and lower flanges (28) and (30) of an I-beam (32). The catcher assembly includes a deflector block (42) having an upper surface (62) defining a perimeter, a lower surface (64), and a cylindrical side surface (60) vertically spacing the upper surface from the lower surface. The upper surface has a vertically extending first inlet port (68), while the side surface defines a first exhaust port (74) extending horizontally through the side surface. The deflector block includes an inlet channel (66) extending normally from said entry port to a predetermined distance within the deflector block to define a bottom surface (70) opposite the entry port. The deflector block also includes a first exit channel (72) extending from the exit port and intersecting the inlet channel at a predetermined distance from the bottom of the inlet channel to define a cushion cavity (76) between the intersection and the bottom to dissipate the kinetic energy of the fluid.
    • 一种用于磨料水射流的紧凑型捕集器组件(20),其具有喷嘴组件(22)和用于产生高速流体喷射(26)的宝石孔(未示出),以在接收捕集器的小区域内切割工件 组件,例如在工字梁(32)的上凸缘和下凸缘(28)和(30)之间。 捕集器组件包括具有限定周界的上表面(62)的偏转器块(42),下表面(64)和垂直地将上表面与下表面间隔开的圆柱形侧表面(60)。 上表面具有垂直延伸的第一入口(68),而侧表面限定水平延伸穿过侧表面的第一排气口(74)。 偏转器块包括从所述入口端口正常延伸到偏转器块内的预定距离的入口通道(66),以限定与入口相对的底面(70)。 偏转器块还包括从出口延伸并且与入口通道相距预定距离与入口通道底部相交的第一出口通道(72),以在相交处和底部之间限定缓冲腔(76),从而消散 流体的动能。
