Claims
- 1. 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.
- 2. The apparatus of claim 1, further comprising a sensor operatively connected to said solenoid via a solenoid driver, whereby, upon sensing the presence of one of said containers, said sensor actuates said solenoid, thereby lifting said first needle stem away from said first valve seat and allowing liquefied gas to forcibly flow from said chamber through said outflow line at said angle into said one of said containers in said open operating state.
- 3. The apparatus of claim 1, said supply tank comprising a second intake line in fluid flow relation with a source of liquefied gas, and said apparatus further comprising a liquid level control valve in fluid flow relation with said second intake line.
- 4. The apparatus of claim 3, said liquid level control valve comprising:
a) a baffle adjacent to said second intake line; b) a float; c) a second needle stem having a first end and a second end; d) a second valve seat within a second valve body, said second valve seat being in fluid flow relation with said second intake line of said supply tank and being adapted to receive said first end of said second needle stem; and e) a rod having a first end fixedly attached to said float and a second end hingedly attached to said second end of said second needle stem and hingedly attached to said valve body, whereby as the level of said liquefied gas rises within said supply tank, said float rises, causing said rod to push said second needle stem toward said valve seat.
- 5. The apparatus of claim 1, wherein said angle is between about 15 degrees and 20 degrees.
- 6. The apparatus of claim 1, said needle stem comprising a first needle portion on said first end thereof and a second needle portion on said second end thereof, said first needle portion being manufactured from Teflon.
- 7. The apparatus of claim 1, said valve body further comprising a threaded portion, said adjustment device comprising a threaded engagement portion which engages said threaded portion of said valve body, said valve body being adjustable in a linear direction relative to said first needle stem by turning said valve body relative to said threaded engagement portion.
- 8. The apparatus of claim 1, said solenoid comprising:
a) a solenoid coil operatively connected to said solenoid driver; b) an armature comprising a first flange and a second flange, said first flange being engaged with a flange on said needle stem; c) an armature back stop; d) whereby, when said solenoid coil is energized, said second flange on said armature contacts said armature back stop and said needle stem is lifted by said armature.
- 9. The apparatus of claim 1, said heater further comprising a cap containing insulation and said at least one heating element, said cap being secured to said valve body.
CROSS-REFERENCE TO RELATED APPLICATION
