The invention concerns the technical field of needleless syringes for injecting an active principle for therapeutic purposes. More particularly, it concerns a needleless syringe for injecting an active principle ( ) initially set between an injector ( ) comprising at least an injection nozzle ( ) contacted with the skin and a wall ( ) mobile under the effect of a propelling system ( ) pressurizing and expelling the active principle through the injector located at the downstream end ( ) of the syringe. In order to produce nozzles passing through a considerable injector thickness and to control the jet coherence distance, said injector ( ) comprises a support ( ) with at least a housing ( ) wherein are stacked plates ( ) each comprising an equal number of orifices aligned to form at least a nozzle ( ) through the stack.
