Title
(EN) AN ARRANGEMENT FOR MUFFLING THE EXHAUST SOUND OF A BOAT MOTOR
(FR) DISPOSITIF DESTINE A AMORTIR LES BRUITS D'ECHAPPEMENT D'UN BATEAU A MOTEUR
Abstract
(EN)
The exhaust gases of a boat motor are led to a buffer chamber (6) with the intention of lowering exhaust sound. The buffer chamber is located beneath the waterline of the boat and is mounted on a trim tab (3) fitted to the transom (1) of the boat. The bottom of the chamber (6) is formed by the trim tab (3) and includes a slot (12), which extends transversely to the direction of water flow. A flow casing (13) through which exhaust gases exit into the water is provided beneath the slot (12).
(FR)
Les gaz d'échappement d'un bateau à moteur sont dirigés vers une chambre (6) tampon dans le but de diminuer les bruits d'échappement. Cette chambre est située sous la ligne de flottaison du bateau et est montée sur un volet correcteur (3) ajusté sur le tableau arrière (1) du bateau. Le fond de la chambre (6) est formée par le volet correcteur (3) et comprend une fente qui s'étend transversalement par rapport à la direction du courant de l'eau. On a monté sous la fente (12) une gaine (13) à travers laquelle les gaz d'échappement sortent pour se diriger dans l'eau.
