A connector for delivering combustion gas to a gas fired appliance from a stationary supply line where the appliance moves toward and away from the supplyline with the connector straightening and flexing between them as the appliance moves. The connector comprises a flexible hose assembly and first and second swivel fittings at respective hose assembly ends. Each swivel fitting defines a gas flow path and comprises a swivel member for communicating the connector with the appliance or the supply line. The hose assembly comprises a flexible metal hose member antitorsion fittings forming ends of the hose assembly connected to respective swivel fittings. The antitorsion fittings comprise pintle and nipple members rotatable relative to each other to prevent torsional stress in the hosemember when the appliance moves relative to the supply line.
La présente invention porte sur un raccord assurant, à partir d'une conduite fixe, l'alimentation en gaz de combustion d'un appareil au gaz. Lorsque l'appareil est rapproché ou éloigné de la conduite d'alimentation, le raccord se redresse et se plie entre la conduite et l'appareil. Le raccord comprend un tuyau souple doté à chacune de ses extrémités d'un raccord articulé. Chacun des raccords articulés définit un circuit d'écoulement et comporte un élément d'articulation assurant la circulation du gaz entre l'appareil et la conduite d'alimentation. Les extrémités du tuyau comportent des raccords métalliques souples antitorsion reliés aux raccords articulés respectifs. Les raccords antitorsion sont dotés d'éléments pivot et mamelon articulés qui préservent le tuyau des efforts de torsion lorsque l'appareil est rapproché ou éloigné de la conduite d'alimentation.
