Abstract
Abstract A milking system includes at least one milking cluster arranged for engagement with a cow's udder during milking, a milk collection conduit, and a backflush fluid conduit. There is provided a disinfecting arrangement including a milking valve assembly which is operative selectively to couple the milking cluster either to the milk collection conduit or to the backflush fluid conduit. The disinfecting arrangement also includes a connection pipe interconnecting the backflush fluid conduit and the milking valve assembly and apparatus for supplying a disinfectant to the backflush fluid at a location along the connection pipe adjacent each milking cluster.

Total Claims: 16
Claim 1
Independent Claim
74 words
A milking system comprising: at least one milking cluster; a milk collection conduit; a backflush fluid conduit; a connection pipe coupled to said backflush fluid conduit; a milking valve assembly operative to couple the at least one milking cluster to the milk collection conduit or, via said connection pipe, to the backflush fluid conduit; and means for supplying a disinfectant to backflush fluid at a location along said connection pipe adjacent each milking cluster.
Claim 2
Dependent Claim
74 words
A milking system comprising: at least one milking cluster; a milk collection conduit; a backflush fluid conduit; a connection pipe coupled to said backflush fluid conduit; a milking valve assembly operative to couple the at least one milking cluster to the milk collection conduit or, via said connection pipe, to the backflush fluid conduit; and means for supplying a disinfectant to backflush fluid at a location along said connection pipe adjacent each milking cluster.
Claim 3
Dependent Claim
21 words
Apparatus according to claim 1 and wherein said means for supplying a disinfectant comprises a one-way valve and a flow restrictor.
Claim 4
Dependent Claim
92 words
Apparatus according to claim 1 and wherein: said at least one cluster comprises a plurality of milking clusters and said milking valve assembly comprises a corresponding plurality of milking valves; said milk collection conduit and said backflush fluid conduit are common to the plurality of clusters and are coupled to each cluster by a corresponding one of said plurality of valves; and said means for supplying comprises means for supplying the disinfectant in which the disinfectant is supplied to a pipe which joins the backflush fluid conduit to the milking valve assembly.
Claim 5
Dependent Claim
37 words
Apparatus according to claim 1 and also comprising a pressurized air conduit and means for supplying pressurized air from said pressurized air conduit together with backflush fluid for providing turbulent flushing of said at least one cluster.
Claim 6
Dependent Claim
18 words
Apparatus according to claim 1 wherein said at least one milking cluster comprises a plurality of milking clusters.
Claim 7
Dependent Claim
134 words
A milking system according to claim 1 and wherein said milking valve assembly comprises: at least one sealing member for preventing fluid communication between said at least one milking cluster and an individual one of said milk collection conduit and said backflush fluid conduit when in a sealing orientation and for allowing fluid communication between said at least one milking cluster and the individual one of said milk collection conduit and said backflush fluid conduit when in a non-sealing orientation; and at least one orientation altering member for changing the orientation of said at least one sealing member, said at least one orientation altering member being normally sealed off from the fluid flowing between said at least one milking cluster and the individual one of said milk collection conduit and said backflush fluid conduit.
Claim 8
Dependent Claim
15 words

Claim 10
Dependent Claim
60 words
A milking system according to claim 6 wherein said at least one sealing member comprises: a first sealing member for preventing and allowing fluid communication between said at least one milking cluster and said milk collection conduit; and a second sealing member for preventing and allowing fluid communication between said at least one milking cluster and said backflush fluid conduit.
Claim 11
Dependent Claim
76 words
A milking system comprising: at least one milking cluster; a milk collection conduit; a backflush fluid conduit; a milking valve assembly operative to couple the at least one milking cluster to the milk collection conduit or to the backflush fluid conduit; and means for supplying a disinfectant to backflush fluid at a location adjacent each milking cluster, said means for supplying a disinfectant comprising a one-way valve and a flow restrictor including a drip irrigation unit.
Claim 12
Dependent Claim
76 words
A milking system comprising: at least one milking cluster; a milk collection conduit; a backflush fluid conduit; a milking valve assembly operative to couple the at least one milking cluster to the milk collection conduit or to the backflush fluid conduit; and means for supplying a disinfectant to backflush fluid at a location adjacent each milking cluster, said means for supplying a disinfectant comprising a one-way valve and a flow restrictor including a drip irrigation unit.
Claim 13
Dependent Claim
95 words
A milking system comprising: at least one milking cluster; a milk collection conduit; a backflush fluid conduit; a connection pipe coupled to said backflush fluid conduit; a milking valve assembly operative to couple the at least one milking cluster to the milk collection concuit or, via said connection pipe, to the backflush fluid conduit; and a pressurized air conduit and means for supplying pressurized air from said pressurized air conduit together with backflush fluid at a location along said connection pipe adjacent each milking cluster for providing turbulent flushing of said at least one cluster.
Claim 14
Dependent Claim
95 words
A milking system comprising: at least one milking cluster; a milk collection conduit; a backflush fluid conduit; a connection pipe coupled to said backflush fluid conduit; a milking valve assembly operative to couple the at least one milking cluster to the milk collection concuit or, via said connection pipe, to the backflush fluid conduit; and a pressurized air conduit and means for supplying pressurized air from said pressurized air conduit together with backflush fluid at a location along said connection pipe adjacent each milking cluster for providing turbulent flushing of said at least one cluster.
Claim 15
Dependent Claim
