1. A method for producing containers that are filled with a liquid filling material from thermally conditioned preforms, the method comprising:
introducing the liquid filling material under pressure through a first filling valve, when the first filling valve is open, into a first preform at a first forming and filling station; and
successively introducing the liquid filing material under pressure through a second filing valve, when the second filling valve is open, into a second preform at a second forming and filling station;
wherein the filling material is supplied from a filling material source,
wherein the filling material is introduced into the first preform by a first displacement pump,
wherein the filling material is successively introduced into the second preform by the same first displacement pump that previously introduced the filling material into the first preform, and
wherein the first displacement pump is provided between the filling material source and the first forming and filling station and the second forming and filling station.
