    • The invention relates to an apparatus (1) for moulding plastic preforms (10) into plastic containers (10a), comprising a clean room (20), at least one blow station (8) comprising a blow mould (4) for shaping the plastic preforms (10) by means of at least one process pressure (89, 91, 92), and comprising a venting device (65) for venting the process pressure (89, 91, 92) or a process pressure reduced to a recovery pressure into the atmosphere, wherein the venting device (65) comprises at least one venting valve (67), by means of which the process pressure (89, 91, 92) or the recovery pressure can be vented into the atmosphere via a sound absorber (69), said apparatus (1) being characterised by a pressure drop safety device (68) for closing the venting valve (67) before the atmospheric pressure level (97) on the venting device (65) is reached.
    • 本发明涉及一种用于将塑料预型件(10)模制成塑料容器(10a)的设备(1),包括一个洁净室(20),至少一个吹气站(8),包括吹塑模具(4) 预成型件(10)通过至少一个工艺压力(89,91,92),并且包括用于排出过程压力(89,91,92)的排气装置(65)或减少到回收压力的过程压力 其中所述排气装置(65)包括至少一个通气阀(67),通过所述通气阀(67)可以经由吸声器(69)将过程压力(89,91,92)或恢复压力排放到大气中 ),所述装置(1)的特征在于在达到通气装置(65)上的大气压力水平(97)之前用于关闭排气阀(67)的压降安全装置(68)。
