ABSTRACT:
A gas injector including a tube extending into the hollow enclosure of a housing. The hollow enclosure of the housing is connected with gas pressure. The outside end of the tube being extendable into the cavity of a plastic material injection mold. That end of the tube defines a valve seat. A valve is seatable on the seat. A rod on the valve extends through the tube into the hollow enclosure of the housing. A spring in a cup shape support normally urges the rod to move the valve onto the valve seat. A solenoid plunger acting on the rod and activated by an electromagnet moves the rod against the spring to raise the valve off the valve seat.
