Claim Text:
1. An apparatus for the shaping of plastics material pre-forms into plastics material containers with a movable carrier on which arc arranged a plurality of shaping stations for shaping the plastics material pre-forms into the plastics material containers, wherein each shaping station has a stressing device which acts upon the plastics material pre-forms for the expansion thereof with a gaseous medium, and with a pressure preparation device which prepares the gaseous medium, wherein the pressure preparation device is arranged in a stationary manner and supplies the shaping stations with the gaseous medium for the expansion of the plastics material pre-forms by way of at least one connection line and wherein a distribution device is provided which distributes the gaseous medium from the pressure preparation device arranged in a stationary manner to the shaping stations arranged in a movable manner, wherein the shaping stations are arranged on a circular conveyor, and each shaping station has at least one pneumatically actuated valve device which is in fluid communication with the pressure preparation device and is supplied by the latter, and wherein the apparatus has a clean room, inside which the shaping stations are arranged at least locally, wherein this clean room is bounded off from an environment by at least one wall, wherein a control air line, which supplies the valve device with a control gas, and a blowing air line, which supplies the shaping stations with the gaseous medium, are separate from each other at least downstream of the distribution device in a flow direction of the gaseous medium, and wherein the distribution device comprises a rotary distributor which is arranged at least partly outside the clean room and within a enter of the circular carrier, said center of said circular carrier being fully enclosed within said clean room in a circumferential direction.
