Abstract
A rotary doser valve includes a stator with a plurality of ports therein which cooperates with a rotor having a plurality of channels therein. The rotor is rotatable against the stator in first and second positions which alternately channel water to and from a doser for refilling an icemaker in a preferred use.
Claims14
A rotary doser valve comprising:
- a stator having a first inlet port, a first outlet port, a first doser port, and a second doser port, said stator comprising a disk having said ports extending axially therethrough;
- and
- a rotor having a switching channel and a bridging channel, and disposed in sliding abutment with said stator, said rotor comprising a disk coaxially abutting said stator disk, and having said channels formed as surface grooves therein,
- said rotor being rotatable against said stator in a first rotor position joining said switching channel in flow communication between said first inlet port and said first doser port, and joining said bridging channel in flow communication between said second doser port and said first outlet port,
- said rotor being also rotatable to a second rotor position joining said switching channel in flow communication between said first inlet port and said second doser port, and joining said bridging channel in flow communication between said first doser port and said first outlet port,
- wherein said first inlet port is disposed in a center of said stator disk, and said first and second doser ports are spaced radially outwardly therefrom and circumferentially spaced apart, and
- wherein said first outlet port is disposed circumferentially between said first and second doser ports.

A rotary doser valve comprising:
- a stator having a first inlet port, a first outlet port, a first doser port, a second doser port, a second inlet port, and a bypass port;
- and
- a rotor having a switching channel, a bridging channel, and a diversion channel, wherein said rotor is disposed in sliding abutment with said stator,
- wherein said rotor is rotatable against said stator in a first rotor position joining said switching channel in flow communication between said first inlet port and said first doser port and joining said bridging channel in flow communication between said second doser port and said first outlet port,
- wherein said rotor is also rotatable to a second rotor position joining said switching channel in flow communication between said first inlet port and said second doser port and joining said bridging channel in flow communication between said first doser port and said first outlet port, and
- wherein said diversion channel is spaced from said switching channel and disposed in flow communication between said second inlet port and said bypass port in both said first and second rotor positions.
