Abstract
Abstract A fluid distribution system comprises a fluid distribution conduit, a fluid inlet and a plurality of closeable fluid outlet branches. The distribution conduit further comprises a plug which can be propelled in response to the fluid pressure, whereas valves are provided with retaining means members for retaining the plug contrary to the fluid pressure for opening the valves. The retaining means become inoperative when the pressure of the fluid is being altered.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
242 words
In a fluid distribution system which comprises a conduit loop through which fluid can flow; means for supplying fluid to said conduit loop; a plurality of valve means located along said conduit loop, each valve means including a fluid outlet branch; and a plug positioned within said conduit loop and capable of passing therealong based on the flow of fluid therethrough, the sequential location of the plug in respective valve means causing fluid to flow through the associated fluid outlet branch, the improvement wherein said plug is in the form of a smooth-surfaced sphere, and wherein each said valve means includes a housing defining an axial passageway therethrough and through which fluid can pass, and a passage member which is axially movable along said axial passageway, said passage member defining an axial channel therein and mounting movable retaining means which project radially inwardly thereof into said axial channel, said movable retaining means being fully extended into said axial channel and preventing movement of said smooth-surfaced sphere through said axial channel at first predetermined axial positions of said passage member within said axial passageway and being repositioned radially outwardly with respect to said axial channel and allowing said smooth-surfaced sphere to move through said axial channel at second predetermined axial positions of said passage member within said axial passageway, the axial positioning of the passage member in said housing determining whether or not fluid will pass through the fluid outlet branch connected thereto.
Claim 2
Dependent Claim

In a fluid distribution system which comprises a conduit loop through which fluid can flow; means for supplying fluid to said conduit loop; a plurality of valve means located along said conduit loop, each valve means including a fluid outlet branch; and a plug positioned within said conduit loop and capable of passing therealong based on the flow of fluid therethrough, the sequential location of the plug in respective valve means causing fluid to flow through the associated fluid outlet branch, the improvement wherein said plug is in the form of a smooth-surfaced sphere, and wherein each said valve means includes a housing defining an axial passageway therethrough and through which fluid can pass, and a passage member which is axially movable along said axial passageway, said passage member defining an axial channel therein and mounting movable retaining means which project radially inwardly thereof into said axial channel, said movable retaining means being fully extended into said axial channel and preventing movement of said smooth-surfaced sphere through said axial channel at first predetermined axial positions of said passage member within said axial passageway and being repositioned radially outwardly with respect to said axial channel and allowing said smooth-surfaced sphere to move through said axial channel at second predetermined axial positions of said passage member within said axial passageway, the axial positioning of the passage member in said housing determining whether or not fluid will pass through the fluid outlet branch connected thereto.
Claim 3
Dependent Claim
108 words
The fluid distribution system as defined in claim 1 wherein said means for supplying fluid to said conduit loop includes a supply device connected in said conduit loop, said supply device including a housing defining a fluid passage therethrough, said housing having an upstream end an a downstream end, and a cap connected to the downstream end of said housing; said housing including an annular chamber radially outwardly of said passageway which, as it extends toward said cap, provides a jet nozzle therewith which communicates with said fluid passage, and wherein said housing includes means forming a fluid inlet for the supply of fluid to said annular chamber.
Claim 4
Dependent Claim
111 words
The fluid distribution system as defined in claim 2 wherein said housing includes an insert means at its upstream end, said insert means defining a flow channel therethrough and an upstream end, a middle portion and a downstream end, wherein said middle portion defines an annular space with said housing, said middle portion including radial channels providing fluid communication between the flow channel provided therein and said annular space; wherein a non-return valve is attached to the downstream end of said insert means to allow fluid flow therethrough in only one direction; and wherein said housing includes means forming a fluid outlet for the removal of fluid from said annular space.
Claim 5
Dependent Claim
21 words
The fluid distribution system as defined in claim 2 wherein means are included to provide a time-controlled pulsed fluid flow therein.
Claim 6
Dependent Claim
46 words
The fluid distribution system as defined in claim 4 wherein a fluid supply conduit is connected to the means forming the fluid inlet of the supply device housing, and wherein said means for providing a time-controlled pulsed fluid flow is connected in said fluid supply conduit.
Claim 7
Dependent Claim
37 words
The fluid distribution system as defined in claim 1 wherein each valve includes a spring means located between said housing and said passage member therein to bias said passage member towards its first said predetermined axial positions.
Claim 8
Dependent Claim
30 words
The fluid distribution system as defined in claim 6 wherein contact between said smooth-surfaced sphere and said retaining means will cause said passage member to move towards its second positions.
Claim 9
Dependent Claim
106 words
The fluid distribution system as defined in claim 6 wherein an annular groove is formed between the housing and the passage member; wherein each of said movable retaining means is in the form of a pin, the head of which is located in said annular groove; and wherein said annular groove is configured such that the heads of the pins are prevented from moving radially outwardly from said passage member when said passage member is in its first predetermined axial positions within said housing but are allowed to move radially outwardly from said passage member when said passage member is in its second predetermined axial positions.
Claim 10
Dependent Claim
28 words
The fluid distribution system as defined in claim 8 wherein said passage member includes two pins extending radially inwardly thereof from radially opposite points along its axial length.
Claim 11
Dependent Claim
51 words
The fluid distribution system as defined in claim 8 wherein said passage member includes three pins extending radially inwardly thereof, two of said three pins being aligned along the axial length of the passage member and the third of said three pins being located therebetween and at a radially opposite point.
