ABSTRACT:
A tank according to the invention comprises a casing, a filling port (5) extending, on the outside of said tank, into a filling neck (7), which is provided with a screw thread having a pitch (p) and which cooperates with a cap (9). The inner surface of the cap cooperating with the screw thread, at least one outlet port for the hydraulic-fluid flow towards a hydraulic circuit. The inner space (3) of the tank is connected with ambient air through two channels (45), that extend from a first lengthwise end (47) of the filling neck (7) to a second lengthwise end (49) of the filling neck (7) and through a helical passage (41) between the filling neck (7) and the cap (9) to connect the inside of the tank with the ambient air to avoid the development of negative pressure in the tank.
