Abstract
Abstract A distribution device, particularly for water, comprising a main conduit communicating with outlet members each normally closed by a respective valve and a body adapted to move through the conduit for sequentially opening each said valve for a period of time depending upon the retention time of the body at a valve, wherein said body includes means for the optional adjustment of said period of time of opening for each valve, and said valve comprising a control-member extending partly into the path of the body.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
84 words
A distribution device for a liquid, particularly water, comprising a main conduit communicating with a plurality of outlet members each of which has a normally closed valve associated therewith, and a body adapted to move through the main conduit for opening said valves in sequence, each for a predetermined period of time depending upon the retention time of the body at each valve, characterized in that the body includes means for the optional adjustment of said retention time of the body at each valve.
Claim 2
Dependent Claim
84 words
A distribution device for a liquid, particularly water, comprising a main conduit communicating with a plurality of outlet members each of which has a normally closed valve associated therewith, and a body adapted to move through the main conduit for opening said valves in sequence, each for a predetermined period of time depending upon the retention time of the body at each valve, characterized in that the body includes means for the optional adjustment of said retention time of the body at each valve.
Claim 3
Dependent Claim
51 words
A distribution device as claimed in claim 1, characterized in that each valve comprises a control-member extending partly into the path of the body and in that said body comprises at least one radially expandable member, the period of time during which said member is in the expanded state being adjustable.
Claim 4
Dependent Claim
29 words
A distribution device as claimed in claim 2, characterized in that the expandable member is formed by a flexible envelope which expands by the supply of a pressurized medium.
Claim 5
Dependent Claim
37 words
A distribution device as claimed in claim 3 including a hydroaccumulator providing said supply of the pressurized medium, a duct communicating said hydroaccumulator with the interior of said envelope and a control valve included in said duct.
Claim 6
Dependent Claim
23 words
A distribution device as claimed in claim 4, characterized in that the control valve is actuated under the action of an electro-magnetic field.
Claim 7
Dependent Claim
34 words
A distribution device as claimed in claim 5, characterized in that the body comprises a programmable memory in which the period of time for which the expansion of the member is maintained is stored.
Claim 8
Dependent Claim
31 words
A distribution device as claimed in claim 6, characterized in that the development of the magnetic field is started by a signal produced by a signal generator disposed near a valve.
Claim 9
Dependent Claim
31 words
A distribution device as claimed in claim 6, characterized in that the development of the magnetic field is started by a signal produced by a signal generator arranged in the body.
Claim 10
Dependent Claim
18 words
A distribution device as claimed in claim 1, characterized in that the main conduit is a ring conduit.
Claim 11
Dependent Claim
19 words
A distribution device as claimed in claim 1, characterized in that the body is moved on by fluid pressure.
Claim 12
Dependent Claim
19 words
A distribution device as claimed in claim 9, characterized in that a fluid reservoir communicates with the ring conduit.
Claim 13
Dependent Claim
27 words
A distribution device as claimed in claim 11, characterized in that the fluid reservoir is connected near a supply duct supplying pressurized liquid to the ring conduit.
Claim 14
Dependent Claim
30 words
A distribution device as claimed in claim 12, characterized in that the supply duct can supply liquid to the ring conduit each time at one of two relatively spaced places.
Claim 15
Dependent Claim
24 words
A distribution device as claimed in claim 11, characterized in that the fluid reservoir communicates with the ring conduit at two relatively spaced places.
Claim 16
Dependent Claim
20 words
A distribution device as claimed in claim 11, characterized in that the fluid reservoir also communicates with the supply duct.
Claim 17
Dependent Claim
37 words
A distribution device as claimed in claim 13, characterized in that the ring conduit includes further valves located in front of the inlet places, viewed in the direction of the fluid flow and adapted to be closed.
Claim 18
Dependent Claim
20 words
A distribution device as claimed in claim 16, characterized in that the further valves are actuated by the moving body.
Claim 19
Dependent Claim
35 words
A distribution device as claimed in claim 17, characterized in that the further valves are actuated electro-magnetically under the action of a switch actuated by the moving body and located externally of the ring conduit.
Claim 20
Dependent Claim
23 words
A distribution device as claimed in claim 1, characterized in that the outlet members are formed by distribution ducts provided with spraying nozzles.
Claim 21
Dependent Claim
22 words
A distribution device as claimed in claim 1, characterized in that the body is electrically fed by batteries included in said body.
Claim 22
Dependent Claim
29 words
A distribution device as claimed in claim 1, characterized in that the body is electrically fed by a generator included in the body and driven by the water pressure.
Claim 23
Dependent Claim
47 words
A distribution device as claimed in claim 6, characterized in that the body includes an address counter whose state is incremented by 1 at every outlet member and in that the memory location is selected and read on the basis of the state of the address counter.
