Abstract

The invention relates to a system for transforming plastics material preforms into plastics material containers having a plurality of blow molding stations which are arranged on a carrier and in each case comprise a blow mold for expanding plastics material preforms into plastics material containers inside this blow mold by means of a pressurized pneumatic medium which is supplied to the respective blow molding station via a pressure supply device and which is at least partially extracted again from the respective blow molding station after the expansion operation via a pressure extraction device. According to the invention it has an energy conversion device, with the aid of which at least part of the potential energy stored in an energy store can be turned into an increase in the potential energy of a pneumatic medium associated with at least one blow mold, wherein the energy conversion device has an intermediate energy storage device, and at least part of the potential energy extracted from the energy store, and the energy transmitted by the energy conversion device, can be stored in the form of kinetic energy in the intermediate energy storage device.
