<p>The invention relates to the realm of needleless syringes used for injecting liquid active substances. Said syringe comprises a reservoir that is enclosed by means of displaceable plugs which trap the liquid. The reservoir is initially isolated from an injector-receptacle (37) which is provided with at least two peripheral injection conduits (38) that are arranged outside the receptacle (37). Said receptacle (37) encompasses a pocket bore (31) which accommodates the plug located downstream such that the optimized inlets (39) of the conduits are unobstructed. The face of the receptacle (37), which is located upstream, comprises a multilobed sealing joint (34) which is disposed parallel to and as close as possible to the edges of the bore (31) and the inlets (39). The aim of the invention is to create an injector-receptacle (37) that is optimized regarding discharging and the resistance thereof to the injection pressure.</p> |
