Zusammenfassung: | A needleless injection device including a piston moved by at least one electromagnetic actuator fed with electric current, the actuator including a stationary structure magnetically interacting with a mobile element in order to exert a force thereon during the injection, one at least from the mobile element and from the stationary structure having, by design, magnetic properties which vary in the direction of movement of the mobile element such as to generate a predefined intensity force on the mobile element during the movement thereof relative to the stationary structure. |
