    • An injection head for the fabrication of a container from a preform (208) accommodated within a mould cavity (205) in the form of a container, said preform (208) having a closed first end thereby defining a preform cavity (212) and an opened second end defining a mouth (210), said injection head being configured to interface with the mouth (110) of the preform (208) and to establish fluid communication between a liquid supply (218) and said mouth (210); said injection head (115) comprising : - an injection valve (224) disposed within the outer shell (222) of the injection head (215) and configured to selectively permit fluid communication through said injection head (215) upon displacement between an opened and a closed position; - an injection head cavity (225) disposed between the injection valve (224) and the outer shell (222) of the injection head (215) and connected to the liquid supply (218); - liquid supply control means (218a); and - control means of the injection valve's opening thereby allowing fluid communication through the injection head. According to the invention, the control means of the injection valve's opening comprise activation means (240) being activated by the liquid under pressure in the injection head cavity (225) when liquid supply (218) is opened.
    • 一种用于从容纳在容器形式的模腔(205)内的预成型件(208)制造容器的注射头,所述预成型件(208)具有封闭的第一端,从而限定预成型腔(212)和 打开的第二端限定出口(210),所述注射头构造成与所述预成型件(208)的口部(110)相接合并且建立液体供应源(218)和所述口部(210)之间的流体连通; 所述注射头(115)包括: - 注射阀(224),其设置在所述注射头(215)的所述外壳(222)内,并且构造成在打开和关闭 封闭位置 - 喷射头腔(225),其设置在所述喷射头(215)的所述喷射阀(224)和所述外壳(222)之间并且连接到所述液体供应(218); - 液体供应控制装置(218a); 以及 - 喷射阀的开口的控制装置,从而允许通过喷射头的流体连通。 根据本发明,喷射阀的开口的控制装置包括启动装置(240),当液体供应(218)打开时,启动装置(240)在喷射头腔(225)中被压力下的液体启动。
