Fluid treatment valve system with nozzle driven turbine

A control valve assembly for controlling a water treatment system such as a water softener or deionization apparatus, comprising:

• a) a water usage turbine having a plurality of vanes and rotatably mounted within a turbine chamber, said turbine chamber communicating with an outlet for treated water;
• b) first and second nozzles for concurrently communicating water from a collection chamber to said turbine vanes in a driving relationship;
• c) each of said nozzles including a passage having a centerline extending toward vanes on said turbine in a converging relationship and intersecting in a region swept by said turbine vanes;
• and
• d) outlet end surfaces of said nozzles defining a confronting surface uniformally spaced from a peripheral portion of said turbine, said surface being continuous along a region bounded by said passages.

A control valve assembly for controlling a water treatment system such as a water softener or deionization apparatus, comprising:

• a) a water usage turbine having a plurality of vanes and rotatably mounted within a turbine chamber, said turbine chamber communicating with an outlet for treated water;
• b) first and second nozzles for communicating water from a collection chamber to said turbine vanes, in a driving relationship;
• c) each of said nozzles including a passage having a centerline extending toward vanes on said turbine in a converging relationship and intersecting in a region swept by said turbine vanes;
• d) outlet sides of said nozzles defining a confronting surface uniformally spaced from a peripheral portion of said turbine, said surface being continuous along a region bounded by said passages;
• and,
• e) at least one of said nozzles being slidably held in a slot defined by a dividing wall in said control valve, said nozzle including structure for maintaining its position within said control valve after said control valve is assembled.

A control valve for controlling a water treatment apparatus, the improvement comprising:

• a) a water usage turbine rotatably mounted within a water receiving chamber, said turbine including a plurality of vanes;
• b) a dividing wall at least partially defining said water receiving chamber and an adjacent water collection chamber;
• c) at least one slot formed in said wall adapted to receive a nozzle for directing water in an impinging relationship with vanes of said turbine;
• d) a slot extension extending from said nozzle receiving slot, arranged to permit the flow of water directly from said collection chamber into said water receiving chamber whereby said nozzle is bypassed;
• e) a drive mechanism coupling said water usage turbine with a regeneration frequency control, adapted to compensate for water that has entered said water receiving chamber through said slot.

A control valve for controlling a water treatment apparatus, the improvement comprising:

• a) a water usage turbine rotatably mounted within a water receiving chamber, said turbine including a plurality of blades;
• b) a first nozzle for directing water flowing along a first path, into an impinging relationship with blades of said turbine;
• c) structure operative for mounting either a plug member or a second nozzle in said control valve, said second nozzle operative to direct water flowing along a second path into an impinging relationship with said blades concurrently with said first nozzle, when said second nozzle is mounted;
• d) said plug member, when mounted in said control valve in place of said second nozzle, being operative to block the flow of water along said second path whereby all water is caused to flow through said first nozzle.
