    Abstract: A method for forming plastic preforms into plastic containers using at least one device for forming preforms into containers, wherein preforms are acted upon by a flowable and, in particular, gas-forming medium and are formed into the containers, wherein the preforms are acted upon with different pressure levels and the flowable medium is stored in at least two reservoirs and is supplied from these reservoirs to the preforms and at least one of these reservoirs is supplied with the flowable medium by a pressure supply device, wherein the target pressure in at least one reservoir is controlled, and wherein this target pressure is compared with an actual pressure in this reservoir. A value characteristic of this comparison is determined. An offset value is controlled on the basis of this value and is controlled in such a way that a predetermined pressure and the target pressure is set in the reservoir.

    Abstract: A device for forming plastic parisons into plastic containers includes at least one forming station arranged on a conveying device and configured to form plastic parisons into plastic containers by applying a gaseous medium, the forming station includes an application device configured to apply the flowable medium to the plastic parisons, and includes a pressure supply device and/or is in fluidic connection with a pressure supply device configured to provide the flowable medium at a prespecified pressure, wherein pressure provided by the pressure supply device is greater than pressure required and/or used for the application to the plastic parisons, wherein the device includes at least one valve device which controls application to the plastic parisons, which valve device is configured to interrupt the supply of air into the container when the pressure of the flowable medium within the container has reached a prespecified pressure level.
