Abstract: A method of controlling the flow of different flow paths of fluid is provided. The method includes rotating a valve to a first position, receiving a first concentrate in the first position, discharging the first concentrate through one of two outlets, rotating the valve to a second position, receiving a second concentrate in the second position, and discharging the second concentrate through one of the two outlets.

Abstract: A selector valve assembly for use in conjunction with an eductor dispensing system which reduces the incidence of product carry-over when the valve is moved from one position to another. The selector valve assembly also reduces the incidence of improper dispensing. In a preferred manner, the selector valve assembly has a single valve member and accommodates four product inlet lines for selectively passing chemical concentrate to two eductors. The selector valve assembly is composed of a minimum of ports, thereby reducing maintenance and cost.

Abstract: A fluid dispenser and method of operating the same. The fluid dispenser can include a wheel driven by diluent passing along a flow path in the fluid dispenser. The wheel can be connected to a pump to pump fluid from a reservoir for dispense into the diluent. In some embodiments, the ratio of wheel rotations to pump cycles is selected to provide a desired and repeatable dilution ratio of concentrated fluid to diluent. The fluid dispenser can be portable and/or disposable, and in some embodiments is adapted for installation on an upper rim of a reservoir wall. Also, the fluid dispenser can be provided with a baffle limiting the velocity and impact of incoming diluent to the wheel driving the pump, thereby improving dosing accuracy of the dispenser in some embodiments.

Abstract: A dispensing assembly for dispensing a mixture of fluids is provided. In some embodiments, the dispensing assembly includes a first valve for selectively permitting fluid flow to a mixing chamber in which a second fluid is introduced, wherein the valve is actuated between open and closed positions responsive to fluid pressure downstream of the mixing chamber. In such embodiments, the fluid pressure downstream of the mixing chamber can change based upon whether fluid is dispensed from a spray gun, wand, nozzle, or other dispensing head of the dispensing assembly.

Abstract: A selector valve assembly controlling the flow of different flow paths of fluid. The assembly includes a body member having a compartment with an end wall, an outlet passage in the end wall, two ports connected to the body member and communicating with the outlet passage in the end wall, and two passages communicating with the compartment. A rotatable member is sealable positioned in the compartment and has a side wall and an end wall. A first passageway extends a distance into the rotatable member from the end wall thereof and a second passageway extends through the side wall thereof and communicates with the first passageway. Rotation of the rotatable member selectively orients the second passageway with each of the two passages to cause liquid in the two passages to pass to the first and second passageways and subsequently to the outlet passage and at least one of the ports.
