    • An aspirating foamer having a water inlet path to admit water into the nozzle assembly, two diametrically opposed foaming material inlet paths perpendicular to the water inlet path, and a conical conduit wherein the pressurized water and foaming materials mix and are allowed to expand; and an air inlet valve at the exiting end of the conical conduit for admitting air; and an exiting path for the foam. In one foamer (2) the conical conduit has an outwardly tapered angle of approximately 5 degrees (from centerline) initially with an immediate increase to an outwardly tapered angle of about 7 degrees in the second half of the conical conduit. In another embodiment foamer (102) according to the invention the conical conduit has an initial taper of 21/2 degrees followed by a 15 degree diffusion angle and then a 7 degree angle.
    • 吸入式起泡器,其具有用于将水引入喷嘴组件的入水路径,两个直径相对的发泡材料入口路径垂直于进水路径,以及锥形管道,其中加压水和发泡材料混合并被允许膨胀; 以及在所述锥形导管的出口端处用于允许空气的进气阀; 和泡沫的出口路径。 在一个起泡器(2)中,锥形导管具有大约5度(从中心线)开始的向外锥形的角度,在锥形导管的后半部立即增加到大约7度的向外锥形的角度。 在另一个实施方案中,根据本发明的起泡器(102),锥形管道具有21/2度的初始锥度,随后是15度扩散角,然后是7度角。

    • A backflushing system capable of being used with an automatic milking device is the subject of this patent application. The system includes a control cam (54) which can be moved linearly to effectuate the various functions. The cam (54) has formed thereon a plurality of lands (64, 66, 68, 70) which operate various actuators (92, 94, 96). The various flushing functions and operation of a fail-safe valve (30) are governed by the actuators (92, 94, 96). In a preferred embodiment, the cam (54) is movable in both forward and reverse directions and is so controlled by a toggle switch (72), movable between two positions, which operates a two position, five way regulation valve (58).
    • 能够与自动挤奶装置一起使用的反冲洗系统是本专利申请的主题。 该系统包括可以线性移动以实现各种功能的控制凸轮(54)。 凸轮(54)上形成有操作各种致动器(92,94,96)的多个平台(65,66,68,70)。 故障安全阀(30)的各种冲洗功能和操作由致动器(92,94,96)控制。 在一个优选实施例中,凸轮(54)可在前后方向上移动,并由拨动开关(72)控制,可在两位置之间移动,该位置操作两位五通调节阀(58)。
