Rotary control valve for a water conditioning system
First Claim
1. A rotary control valve arrangement for a liquid conditioning system including:
- a housing having a side wall forming a chamber and a plurality of ports formed in said side wall;
a rotor having a first end, a second end and a longitudinal central axis, said rotor adapted to be located within said chamber of said housing and to be selectively rotatable about said central axis, said rotor including a generally tubular wall extending along said central axis, said tubular wall defining a longitudinally extending central fluid path, said rotor including an inlet port adapted to provide fluid communication between said central fluid path and a source of untreated liquid, said rotor including a plurality of longitudinal sectors, a plurality of said sectors including a plurality of radial chambers, one or more of said radial chambers including an aperture providing fluid communication between said central fluid path and said one or more of said radial chambers, each said radial chamber including a peripheral aperture adapted to selectively place said radial chamber in fluid communication with one or more of said ports in said housing and at least one of said radial chambers including a peripheral aperture adapted to selectively place said at least one radial chamber in fluid communication with more than one of said ports in said housing;
wherein said rotor is selectively rotatable about said central axis to a selected one of a plurality of rotational positions such that said radial chambers of one of said sectors are aligned in juxtaposition and in fluid communication with said ports of said housing, whereby various fluid paths extending through said rotor and said ports are opened and closed as said rotor is selectively rotated between said rotational positions.

Abstract
A rotary control valve is provided for a liquid conditioning system. The rotary control valve includes a housing having a chamber formed about a central axis. The housing includes a plurality of ports aligned with one another along an axis generally parallel to the central axis. A rotor is located within the chamber and is selectively rotatable about the central axis. The rotor includes a central tubular wall extending along the central axis which includes a central fluid flow path. The rotor includes an inlet port adapted to provide fluid communication between the central fluid flow path and a source of untreated liquid. The rotor also includes a plurality of longitudinal sectors wherein each sector includes one or more radial chambers located in one or more tiers of the sector. One or more of the radial chambers in each sector includes an aperture to provide fluid communication between the central fluid flow path and the radial chamber. The radial chambers include respective peripheral apertures adapted to selectively place the radial chambers of a sector in fluid communication with one or more of the ports of the housing when the sector is rotated into alignment with the ports in the housing. Selective rotation of the rotor about the central axis to a selected rotational position opens and closes various fluid paths through the rotor and the housing.
