摘要： A dispenser selectively mixes one or more chemical fluids into a motive fluid such as water by using diverting motive fluid to one or more channels formed in an eductor body, at least one of the channels being an eductor. When the motive fluid passes through the eductor, a selected chemical fluid is eductively drawn into the venturi of the eductor, producing a mixed fluid having a desired total flow rate and dilution ratio. Additional dilution ratios, flow rates, and chemical fluids are selectable by diverting motive fluid to another channel or combinations of channels. Carry-over of chemical fluid between dispensing is avoided by diverting the motive fluid rather than by diverting the concentrated chemical fluid.
摘要翻译：分配器通过使用转移运动流体到形成在喷射器体中的一个或多个通道来选择性地将一种或多种化学流体混合到诸如水的运动流体中，至少一个通道是喷射器。当运动流体通过喷射器时，选择的化学流体被喷射到喷射器的文氏管中，产生具有所需总流速和稀释比的混合流体。通过将动力流体转移到另一个通道或通道的组合来选择额外的稀释比，流速和化学流体。通过转移运动流体而不是通过转移浓缩的化学液体来避免分配之间的化学液体的转运。

摘要： A dispenser for dispensing at two flow rates eductively draws a chemical fluid such as a concentrated cleaning solution for diluting with a motive fluid such as water. Using eduction rather than gravity feed provides a consistent dilution ratio over a range of pressures of the motive fluid. A chemical reservoir contains the chemical fluid and a bottle insert assembly for interfacing to the dispenser. The bottle insert assembly seals an opening to the reservoir when the reservoir is not inserted in the dispenser, preventing leaks. Also, the bottle insert assembly includes dual pickup tubes, each with a purge accumulator, to allow dual rate flow at the same or different dilution ratios as well as drawing back unused chemical fluids from the dispenser to avoid carryover or contamination.

摘要： An improved venturi eductor for proportional dispensing of chemicals into flowing water includes a large antisyphoning air gap to satisfy water system regulations. Specialized baffles are provided to prevent discharge of spray and mist from the air gap. Further, the shape and location of various nozzles within the device creates a slight suction at the air gap to further limit overspray.

The reservoirs are filled with new concentrate from a current fill level mark to a full level mark and the volume of concentrate filled between the marks is calculated for filling and inventory purposes. The front handle is narrower than the reservoir sides and flanges at the upper end of the reservoir to facilitate in and out sliding of the reservoir for billing and cleaning.

摘要： An ultra-lean dilution apparatus is provided for proportioning minute quantities of a first fluid, such as a concentrated cleaning solution, for mixing into a second fluid, such as tap water, which provides improved performance and which can be manufactured by assembling several molded components with little or no machining. The dilution apparatus (20) provides a selective pressure drop in a conduit (22) by including a plurality of dilution disks (50a-50f), each dilution disk (50a-50f) having a tortuous path (52a-52f) of sufficient cross-sectional area to be resistant to clogging and having a sufficient number of sharp turns to create a desired pressure drop. While each disk (50a-50f) produces a predetermined drop, the serial configuration of the tortuous paths of the plurality of dilution disks is additive to produce a range of dilution suitable for the chemicals used. Advantageously, the tortuous path of a first of the plurality of dilution disks (50a) is recessed into a front face so that bringing the front face (54a) of the first dilution disk (50a) in contact with a back face (55b) of a second dilution disk (50b) completes the tortuous path (52a). Furthermore, a blind intake (58a) of the tortuous path (52a) of the first dilution disk (50a-50f) selectively communicates with an output port (56b) of another tortuous path (52b) on a front face (54b) the second dilution disk (50b).
摘要翻译：提供了一种超稀薄稀释装置，用于将微量的第一流体（例如浓缩清洁溶液）配比，以混合到第二流体例如自来水中，其提供改进的性能，并且可以通过组装多个模制部件很少或不加工。稀释装置（20）通过包括多个稀释盘（50a-50f）在管道（22）中提供选择性压降，每个稀释盘（50a-50f）具有足够交叉的曲折路径（52a-52f）以防止堵塞并具有足够数量的急转弯以产生期望的压降。当每个盘（50a-50f）产生预定的液滴时，多个稀释盘的曲折路径的串联配置是相加的，以产生适用于所用化学品的稀释范围。有利地，多个稀释盘（50a）中的第一个稀释盘（50a）的曲折路径凹入到前表面中，使得第一稀释盘（50a）的前表面（54a）与第一稀释盘第二稀释盘（50b）完成曲折路径（52a）。此外，第一稀释盘（50a-50f）的曲折路径（52a）的盲进口（58a）选择性地与前表面（54b）上的另一曲折路径（52b）的输出端口（56b）连通，第二稀释盘稀释盘（50b）。
