Title
(EN) GAS SUPPLY SYSTEM FOR A GAS ENGINE
(FR) SYSTÈME D'ALIMENTATION EN GAZ POUR UN MOTEUR À GAZ
Abstract
(EN)
A gas supply system for a gas engine is described, comprising a double-walled pipe (10) with an inner and an outer pipe (10a, 10b) for the supply of fuel gas to the cylinder units of the engine, where said double wall provides an outer, longitudinally running annular space along the whole length of the pipe (10) and where the fuel gas is transported in the inner pipe (10b). The double- walled pipe (10) along the engine is divided into sections (12) between respective cylinders, where a coupling piece (14) is arranged between said sections (12) to link the sections, and the coupling piece (14) is internally open and comprises one or more channels (16) to link the longitudinally running annular space between respective sections (12) and a boring (20) to take out the fuel gas from the inner pipe (10b) and through an outlet (22) to a respective cylinder unit.

La présente invention se rapporte à un système d'alimentation en gaz pour un moteur à gaz. Ledit système comprend une conduite à double paroi (10) ayant une conduite interne et une conduite externe (10a, 10b) pour l'alimentation du gaz combustible aux unités de cylindre du moteur, ladite double paroi offrant un espace annulaire externe s'étendant longitudinalement sur toute la longueur de la conduite (10) et le gaz combustible étant transporté dans la conduite interne (10b). La conduite à double paroi (10) le long du moteur est divisée en sections (12) entre les cylindres respectifs, une pièce de couplage (14) étant agencée entre lesdites sections (12) pour relier les sections et la pièce de couplage (14) étant ouverte à l'intérieur et comprenant un ou plusieurs canaux (16) pour relier l'espace annulaire s'étendant longitudinalement entre les sections respectives (12) et un alésage de cylindre (20) pour faire sortir le gaz combustible de la conduite interne (10b) et le transmettre à travers un orifice de sortie (22) jusqu'à une unité de cylindre respective.
