Abstract
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 ().
