Abstract

The invention concerns a hydraulic connector ( 140 ) forming a distributor or manifold for a hydraulic circuit of a fluid purification system ( 100 ) having a purified fluid inlet ( 142 ) and three outlets ( 143, 144, 145 ), characterized in that the inlet ( 142 ) is connected directly to a first outlet ( 143 ) of the three outlets by a pipe and in that a second pipe ( 141 ) is hydraulically connected to the first pipe between said inlet ( 142 ) and said first outlet ( 143 ) and to a third pipe having two ends forming the other two outlets ( 144, 145 ) of the connector.

Claims (6)

1. Water purification system including a purified water recirculation loop including water treatment means and at least one point of use of purified water, characterized in that the system is equipped with a connector downstream of the treatment means, said connector comprising: a purified fluid inlet and three outlets, wherein said inlet is connected directly to a first outlet of the three outlets by a pipe and wherein a second pipe is hydraulically connected to said first pipe between said inlet and said first outlet and to a third pipe having two ends forming the other two outlets of said connector, the inlet whereof is connected to the outlet of said treatment means and one outlet whereof is connected to the recirculation loop upstream of the treatment means, the system including two parallel branches that come together at the point of use and are connected to the other two outlets of the connector.

2. Water purification system according to claim 1 , wherein the outlet of the device connected to the recirculation loop is an outlet other than said first outlet of the device connected directly to the inlet by said first pipe.

3. Water purification system according either to claim 1 or to claim 2 , wherein it is equipped, downstream of the connector, with two parallel branches that are connected to the recirculation loop at two different points downstream of the water purification means and come together at the point of use.

4. Water purification system according to claim 3 , wherein the two parallel branches come together at the inlet of a solenoid distribution valve enabling purified water to be distributed at the point of use, through a filter or a polishing cartridge.

5. Water purification system according to claim 1 or 2 , wherein the two parallel branches come together at the inlet of a solenoid distribution valve enabling purified water to be distributed at the point of use, through a filter or a polishing cartridge.

6. Water purification system according to claim 1 , wherein said connector is H-shaped.
