ABSTRACT:
The present invention relates to a system for feeding the engines of a space vehicle with at least one liquid propellant, the system comprising for the purpose of storing said liquid propellant under a pressure greater than the feed pressure, firstly a main tank having no liquid expulsion device, and secondly an auxiliary tank that is smaller than the main tank and that is provided with a device for separating the liquid phase from the gas phase, switching means enabling the auxiliary tank to be selectively refilled with liquid propellant from the main tank; such that liquid propellant that is free from pressurization gas bubbles can always be delivered regardless of the flight conditions of the vehicle, and in particular when it is not possible to take said liquid propellant from the main tank.
