Title:
VAPORIZATION GAS SUPPLY DEVICE
Document Type and Number:
Japanese Patent JP3227404
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a vaporization gas supply device wherein a mixed gas comprising a vaporization gas of fuel and motor is supplied in a stable concentration.
SOLUTION: The vaporization gas supply device comprises a liquid injection hole 11 for injecting a liquid, a dilution gas injection hole 21 where a dilution gas is injected, a front-end chamber 1 where an injected liquid is heated to be a vaporized gas, a jetting nozzle 3 where the vaporized gas and the diluted gas are mixed and jetted, a mixing chamber 4 where a vaporized gas and diluted gas jetted from the jetting nozzle 3 are diffused and heated to be mixed together for generating a mixed gas, an electric heater 5 for heating the front- chamber 1 and the mixing chamber 4, and a mixed gas supply opening 41 to supply the mixed gas generating in the mixing chamber 4. Since a liquid is perfectly vaporized to be a vaporized gas in the front-end chamber 1, no such non-steady phenomenon as bubble jet is eliminated at supply to the jetting nozzle 3, so that a vaporized gas is fed to the jetting nozzle 3 at a constant rate at always for stable concentration.
