Abstract:
(EN) A fuel-conveying device (1) for a fuel injection device of an internal combustion engine, having a gas tank (2) for receiving a gaseous fuel, wherein the gaseous fuel can be conveyed by a pump (3) out of the gas tank (2) into a high-pressure region (8), which comprises a buffer tank (7) and a high-pressure rail (11), wherein the high-pressure rail (11) is connected to at least one injector (13) and the high-pressure region (8) is connected to at least one gas storage tank (20).
(FR) L’invention concerne un dispositif de refoulement de carburant (1) destiné à un dispositif d’injection de carburant d’un moteur à combustion interne, comprenant un réservoir de gaz (2) destiné à contenir un carburant gazeux, le carburant gazeux pouvant être refoulé par une pompe (3) du réservoir de gaz (2) vers une zone haute pression (8) qui comprend un réservoir tampon (7) et une rampe haute pression (11), la rampe haute pression (11) étant reliée à au moins un injecteur (13) et la zone haute pression (8) étant reliée à au moins un accumulateur de gaz (20).
(DE) Kraftstofffördereinrichtung (1) für eine Kraftstoffeinspritzeinrichtung einer Brennkraftmaschine mit einem Gas-Tank (2) zur Aufnahme eines gasförmigen Kraftstoffes, wobei der gasförmige Kraftstoff durch eine Pumpe (3) aus dem Gas-Tank (2) in einen Hochdruckbereich (8), welcher einen Buffertank (7) und ein Hochdruckrail (11) umfasst, förderbar ist, wobei das Hochdruckrail (11) mit mindestens einem Injektor (13) und der Hochdruckbereich (8) mit mindestens einem Gasspeicher (20) verbunden ist.
