Abstract
Abstract A liquid distributor valve assembly in which an impeller means is disposed in a housing and is rotatable in the housing by the force of liquid entering the housing. A valve assembly is adapted to rotate in the housing in a manner to selectively control the flow of fluid through a plurality of outlets, and a gear arrangement selectively rotates the valve means in response to rotation of the impeller means.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
135 words
A liquid distributor valve assembly for selectively directing liquid from a source to a plurality of delivery conduits, said system comprising a housing having an inlet for receiving liquid from said source, a plurality of outlets adapted for connection to said conduits, and a chamber communicating said inlet and said outlets; impeller means disposed in said chamber in the path of the liquid entering the housing through said inlet, said impeller means being rotatable in said housing by the force of said liquid; valve means for moving in said chamber in a manner to control the flow of fluid through said outlets; and two gear systems responsive to movement of said impeller means for moving said valve means, said gear systems operating independently of each other to reduce the driving torque applied through each system.
Claim 2
Dependent Claim
135 words
A liquid distributor valve assembly for selectively directing liquid from a source to a plurality of delivery conduits, said system comprising a housing having an inlet for receiving liquid from said source, a plurality of outlets adapted for connection to said conduits, and a chamber communicating said inlet and said outlets; impeller means disposed in said chamber in the path of the liquid entering the housing through said inlet, said impeller means being rotatable in said housing by the force of said liquid; valve means for moving in said chamber in a manner to control the flow of fluid through said outlets; and two gear systems responsive to movement of said impeller means for moving said valve means, said gear systems operating independently of each other to reduce the driving torque applied through each system.
Claim 3
Dependent Claim
37 words
The assembly of claim 2, wherein each gear system includes a plurality of gear means, the gear means of one of said gear systems extending diametrically opposite the respective corresponding gear means of the other gear system.
Claim 4
Dependent Claim
43 words
The assembly of claim 2, wherein each gear system includes a first gear in driving engagement with said impeller, a second gear rotatably mounted on said valve means and at least one intermediate gear in driving engagement with said first and second gears.
Claim 5
Dependent Claim
25 words
The assembly of claim 3, further comprising a stationary ring gear disposed in said chamber in engagement with the second gear of each gear system.
Claim 6
Dependent Claim
43 words
The assembly of claim 2, wherein said valve means is in the form of a disc rotatably mounted in said chamber and having at least one opening extending therethrough which is adapted to successively register with said outlets upon rotation of said disc.
Claim 7
Dependent Claim
31 words
The assembly of claim 5, further comprising a valve seat extending around each of said outlets, said disc adapted to seat on said valve seats to prevent flow through said outlets.
Claim 8
Dependent Claim
20 words
The assembly of claim 6, wherein said valve seats are flared radially outwardly to minimize frictional contact with said disc.
Claim 9
Dependent Claim
19 words
The assembly of cliam 5, wherein said disc extends in a spaced relation to the floor of said housing.
Claim 10
Dependent Claim
19 words
The assembly of cliam 5, wherein said disc extends in a spaced relation to the floor of said housing.
Claim 11
Dependent Claim
30 words
The assembly of claim 5, wherein said opening in said disc is sized so as to simultaneously register with a portion of two adjacent outlets during rotation of said disc.
