A mechanism 1 transfers a fluid between vessels in closed circuit communication, the variable volume vessels 4e, 4c being in fluid communication. Preferably the mechanism is a rotating mechanism and the vessels are hinged to an arm 2 pivoted to a support 12. In a stop/start position AP of the arm, the highest vessels 4e is in expanded condition and causes rotation of the arm 2 due to gravity until the vessels find themselves in reversed positions, with the expanded vessel 4e down and the compressed vessel 4c up. Expansion/compression means 8 act on the vessels as a consequence of gravity effect, thus causing the fluid to shift from the lowermost vessel to the uppermost vessel. The fluid transfer leads to the restoring of the initial condition and to a new rotation of the arm and vessels, bringing the expanded vessel downwards and the compressed vessel upwards. The vessels oscillate to help the arm rotation. In a further embodiment, the vessels move toward and away from the rotation axis of the arm, to increase the momentum. The fluid is thus transferred from one vessel to another without the need of any action from an operator. |
