Needleless injectors for injecting fluids subcutaneously without a needle are generally discussed herein with particular discussions on needleless injectors for injecting a volume of fluid through two or more nozzles. The injectors can have a spring driven force generating component or a gas driven type. The injectors can have a fluid handling component having a single integrally molded component or one that is multi-component. The entire injector can be disposable or, alternatively, only the fluid handling component is disposable. The force generating component can be reset for use with a new or scone fluid handling component. Finally, the two or more discharge nozzles can be located at the discharge end of a single ampule. Alternatively, the two or more nozzles can be multiple single orifice ampules mounted on one or more force generating components.
