| Abstract: | Under the severe demand of the Water/Metal Fuel Motor on the flux of water in the starting period,a new type of pressure-adaptive and flux-constant orifice was brought forward.The flux-constant principle of this orifice with pressure-adaptability was analyzed theoretically.Experiments were carried out.Their results show that the orifice can satisfactorily adjust the flux resistance automatically and keep the flux constant. |

| Keywords: | pressure-adaptive flux-constant orifice water/metal fuel motor |
