Patent ID: 8262384

Claim:
A blow moulding apparatus for expanding plastic preforms into plastic containers, comprising: a blow piston extending in a longitudinal direction; a blow nozzle extending from the blow piston in the longitudinal direction, the blow nozzle being configured to apply a gaseous medium to a preform for the expansion thereof; a connection device structured and arranged to supply the gaseous medium to the blow moulding apparatus via at least two connection lines; a control block arranged between the connection device and the blow piston, the control block being configured to control the supply of the gaseous medium during the expansion process using at least partially varying pressure levels, the control block having a plurality of channels for guiding the gaseous medium, the plurality of channels being separated from each other at least in sections, the plurality of channels being distributed in a circumferential direction of the control block; at least two valves on an outer circumference of the control block, said valves being distributed in a circumferential direction around the control block, said valves being controlled independent of one another for controlling the supply of the gaseous medium to the blow nozzle; and a distribution arrangement configured to guide the gaseous medium into said channels, said distribution member being arranged between the connection device and the control block if viewed in the flow direction of the gaseous medium, said channels extending within the control block at least in sections substantially parallel to the longitudinal direction of the blow piston.
