## Abstract

A hydraulic manifold fluidly connects at least two series of tanks. The hydraulic manifold includes at least one filling inlet, at least one emptying outlet, a filling pipe, an emptying pipe, and the same number of branch pipes as there are series of tanks. The branch pipe comprises, at a branch pipe inlet, a connection to the filling pipe via an upstream non-return valve. The branch comprises, at a branch pipe outlet, a connection to the emptying pipe via a downstream non-return valve.

## Claims

### Claim 1

A hydraulic manifold that fluidly connects at least two series of tanks, the hydraulic manifold comprising:
at least one filling inlet and at least one emptying outlet;
a filling pipe;
an emptying pipe; and
a same number of branch pipes as there are series of tanks, and wherein the branch pipes comprise at least a first branch pipe and a second branch pipe, and wherein the series of tanks comprise at least a first series and a second series;
wherein the filling pipe comprises a connection to said at least one filling inlet and a connection to an inlet of each of the branch pipes;
wherein the emptying pipe comprises a connection to an outlet of each of the branch pipes and a connection to said at least one emptying outlet;
the first branch pipe comprising, at a first branch pipe inlet, a connection to the filling pipe, via a first upstream non-return valve, going in a direction from the filling pipe to the first branch pipe and, at a first branch pipe outlet, a connection to the emptying pipe via a first downstream non-return valve, going in a direction from the first branch pipe to the emptying pipe and further comprising, between the first upstream non-return valve and the first downstream non-return valve, at least one first connection to a tank of the first series; and
the second branch pipe comprising, at a second branch pipe inlet, a connection to the filling pipe via a second upstream non-return valve, going in a direction from the filling pipe to the second branch pipe and, at a second branch pipe outlet, a connection to the emptying pipe via a second downstream non-return valve, going in a direction from the second branch pipe to the emptying pipe and further comprising, between the second upstream non-return valve and the second downstream non-return valve, at least one second connection to a tank of the second series.

### Claim 2 (depends on 1)

The hydraulic manifold as claimed in claim 1, wherein each of said tank is connected to the hydraulic manifold via a semi-direct solenoid valve.

### Claim 3 (depends on 1)

The hydraulic manifold as claimed in claim 1, wherein, within said series of tanks, tanks with similar thermal characteristics are grouped together.

### Claim 4 (depends on 3)

The hydraulic manifold as claimed in claim 3, wherein said tanks with similar thermal characteristics are tanks with substantially identical diameter-to-length ratios.

### Claim 5 (depends on 1)

The hydraulic manifold as claimed in claim 1, wherein the hydraulic manifold is made in one piece, since the hydraulic manifold is assembled together.

### Claim 6 (depends on 1)

The hydraulic manifold as claimed in claim 1, of modular design, with a base module and at least one add-on module:
the base module comprising
the filling pipe,
the emptying pipe and the first branch pipe,
the filling pipe comprising the connection to the filling inlet, the connection to the first branch pipe inlet of the first branch pipe, and a first upstream extension connection,
the emptying pipe comprising the connection to the first branch pipe outlet of the first branch pipe, the connection to the emptying outlet, and a first downstream extension connection,
the first branch pipe being unchanged, and the at least one add-on module comprising
the second branch pipe, wherein the second branch pipe is unchanged, and further comprising, at the second branch pipe inlet, a second upstream extension connection complementary to the first upstream extension connection and, at the second branch pipe outlet, a second downstream extension connection complementary to the first downstream extension connection.

### Claim 7 (depends on 1)

The hydraulic manifold as claimed in claim 1, wherein at least one of the first branch pipe and the second branch pipe comprises a pressure sensor.
