Abstract
The present invention is directed to a flow rate selector having a high flow position and a low flow position. The flow rate selector has a flow selector knob having a web. The web has a flat surface. At least two seals are mounted on the flat surface of the web. A retaining piece has two orifices of differing cross-sectional areas. The flow selector knob is rotatable relative to the retaining piece such that at least one seal can be aligned with either of the orifices to prevent fluid flow there through while allowing fluid flow through the other orifice. Cover 656 has conical outside diameter that seals against chamber in 654. This protects chamber 720 from foreign particles.
