Abstract:
1. A gas control valve comprising: a housing having an inlet, a seat, and an outlet; a hollow plunger inside the housing, the hollow plunger having a fixed segment and a poppet segment, the poppet segment including a poppet conduit and slideable within the housing; a spring encircling the poppet segment, the spring biasing the poppet segment toward the seat; and a solenoid coil encircling the housing; and wherein the gas control valve is alternatively: energizable to slideably bias the poppet segment toward the fixed segment such that the poppet segment disengages from the seat and a gas is permitted to flow through the hollow plunger; and de-energizable to allow the spring to bias the poppet segment away from the fixed segment such that the poppet segment engages with the seat to prevent the gas from flowing out of the outlet.
