Hydraulic manifold

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.
