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 first intake line in fluid flow relation with a supply tank; c) a chamber in fluid flow relation with said first intake line; d) an injector valve located within said chamber, said injector valve comprising a first needle stem having a first end and a second end, a first valve seat within a first valve body, and a substantially straight outflow line; e) an adjustment device operatively connected to said first valve seat for adjusting the position of said first valve seat relative to said first needle stem; f) a solenoid operatively connected to said first needle stem; g) a biasing device adjacent to said second end of said first needle stem biasing said first end of said first needle stem toward said first valve seat; h) a heater comprising at least one heating element positioned adjacent to said outflow line; i) an open operating state whereby 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 j) a closed operating state whereby said needle stem is seated within said valve seat, blocking said liquefied gas within said chamber from entering said outflow line.
