Abstract:
A fluid dispersing apparatus, comprising:a first fluid supply; a second fluid supply; and a proportioner for controlling the combination of one volume of a first proportioned fluid from the first fluid supply into another larger volume of a second fluid from the second fluid supply, the proportioner including: at least two channel carriers, at least one channel carrier having a face in sliding contact with a face of another channel carrier; each channel carrier comprising a channel segment having a tortuous path, said tortuous path having a blind end and a through port end; each channel carrier also comprising a through port communicating with said through port end; each channel carrier being slidably moveable with respect to another channel carrier between a channel segment engaged position and a channel segment bypass position, said carrier being in a channel segment engaged position when the blind end of the channel therein is in fluid communication with a through port of another channel carrier, said carrier being in a channel segment bypass position when the through port thereof is aligned with the through port of another channel carrier disposed operably upstream thereof; and an operative proportioning channel for said proportioner being defined by the channel segments in carriers disposed in the engaged position and by the through ports of carriers disposed in the channel segment bypass position, the channel segments in carriers disposed in the bypass position being operatively disconnected from said proportioning channel.
