Abstract
The invention pertains to a blow molding machine with at least one blow mold for producing hollow bodies from heated preforms, at least one blow nozzle for leading the blow air into the preforms and a plurality of valves for controlling the feeding and the removal of the blow air to and from the blow nozzle, whereby the valves are arranged on an annular valve carrier surrounding the blow nozzle. This results in a compact design with short cycle times.
