Abstract: Aiming at the problem of the needle free injector could not realize the continual jet and adjust doses, a volume adjustable continuous jet needle\|free injector driven by voice coil motor was built (continuous jet injector). The operating principle of the continuous jet injector was introduced. The theory of the continuous jet injector was analyzed. The theoretical model was built and the nozzle pressure theoretical curve was obtained. The system of pressure tests was built and the jet pressure force was tested dynamically, the nozzle pressure experimental curve was obtained. The results indicate that the theoretical curve identical with the experimental curve and the experimental data is smaller than the theoretical data in the same conditions. In addition, the coil electricity is increasie with the increasing of jet doses.

 

Key words: voice coil motor; dose adjustable; continuous jet; nozzle pressure; coil electricity
