In a water-cooled inner combustion engine (), in particular for equipping scooters and motorcycles, the arrangement of the outer cooling tubes connected to a radiator is simplified by arranging a by-pass valve (), arranged directly on the engine block () at a discharge opening () obtained therein, which, when the cooling water is lower than a reference temperature, prevents the water circulation in the radiator () and it addresses it through a by-pass line () by implementing a cooling circuit wholly included in the engine block (). 1128911121398311829. A water-cooled internal combustion engine () , for equipping scooters and motorcycles , having an engine block () , obtained from one only single-piece melting and with a driving axle (A) substantially perpendicular to a longitudinal development of the internal combustion engine , and a cooling system comprising a radiator () , a relative fan () and a water circulating pump () comprising an intake nozzle () and a discharge nozzle () , wherein the fan () of the radiator () is mounted directly on a crankshaft () from which a driving force for said cooling water circulation pump () is derived , the radiator () being arranged laterally to the engine block () , with the fan () lying on a plane substantially parallel to said longitudinal development ,{'b': 11', '2', '8, 'claim-text': [ [{'b': 16', '17', '8', '2', '16', '17', '2', '18', '18', '23', '12', '11, 'a discharge line () and a extraction line () connecting the radiator () to said engine block (), said discharge and extraction lines (, ) being constituted by tubes outside the engine block () with respective discharge openings (), formed in said engine block (), and intake opening () connected to said intake nozzle () of the pump ();'}, {'b': 24', '25, 'an inner circuit portion (, ) for extracting heat from the engine;'}], 'a first cooling circuit having, {'b': 2', '26', '18', '12', '11', '24', '25', '1, 'a second cooling circuit wholly included in said engine block ...
