Zusammenfassung:	A propellant supply device ( 10 ) is provided for a vehicle ( 11 ) having a main propulsion motor ( 12 ) and having an attitude control system ( 11 ) including a plurality of thrusters ( 14 A, 14 B, 14 C, . . . , 14 F). The improved device comprises: a pressure vessel ( 15 ); first and second movable walls ( 20, 21 ) operatively arranged within the pressure vessel and dividing the interior space therewithin into three separate sealed chambers ( 22, 23, 24 ) from each of which fluid may be supplied; a first fluid (e.g., a first bipropellant) in one of the chambers; a second fluid (e.g., a second bipropellant) in a second of the chambers; and a third fluid (e.g., ammonia) in a third of the chambers, the third fluid being a volatile liquid having a liquid phase and a gaseous phase, and wherein all three chambers are pressurized to the vapor pressure of the third fluid.
