THE DESIGN OF A PELLET INJECTOR WITH CYCLE REFRIGERATOR

The design of the first set multi barrels hydrogen pellet injector with G M cycle refrigerator has been designed. The in situ condensation is employed in this injector for making 25 pellets in 25 gun barrels simultaneously. The using of G M refrigerator has the advantages in following field: ease for operation, high reliability and the flexibility are guaranteed and reduction the operation cost. The prime principle, goals of the design, construction, layout of the components, choice of engineering parameters and the possible extended direction are introduced.
