Abstract:
An injector apparatus for injecting a liquefied gas into containers at an angle to said containers in a high-speed filling operation, comprising:a) a central longitudinal axis which is positioned at an angle to the central longitudinal axis of said containers; b) an injector valve located within a chamber, said injector valve comprising: i) a needle stem having a tapered end portion; ii) a valve body having a valve seat which is adapted to receive said tapered end portion of said needle stem; and iii) a substantially straight outflow line in said valve body; c) an adjustment device operatively connected to said first valve seat for adjusting the position of said valve seat relative to said needle stem; d) an open operating state whereby said tapered end portion of said needle stem is positioned away from said valve seat, allowing said liquefied gas within said chamber to flow out of said outflow line and into one of said containers; and e) a closed operating state whereby said tapered end portion of said needle stem is seated within said valve seat, blocking said liquefied gas within said chamber from entering said outflow line.
