摘要： PROBLEM TO BE SOLVED: To provide the higher power and high functionability by forming a ring-shaped duct by a ring having a semi-circular cross section, and comprising a number of orifices on a curved outer face of the ring. SOLUTION: A power unit mainly comprises an injection valve for the liquid energy support, a decomposition chamber assembled with two reaction chambers, and an injecting part connected with the decomposition chamber and having a divergent nozzle. An inflow port of an injection tube in the reaction chamber is covered by a ring 19 brazed to a head plate, the so-called aspirator ring. The ring 19 has a ring-shaped duct 20, and the energy support, that is, hydrazine flown to the ring-shaped duct 20, is uniformly and finely distributed by the holes arranged at equal intervals, to be discharged to the reaction chambers. Further the different numbers of holes 21 are respectively formed on at least three different circular arcs in the ring 19.
