Abstract
Injector for transcutaneous injections without needle, suitable for carrying out injections without a needle by means of a jet of liquid at high pressure drawn from at least one ampoule 20 comprising at least one head 12 associated with nozzle/head means 14, 114 bearing the hole 15 for the expulsion of the liquid to be injected and at least one bottom part 13 comprising the means for filling the injector 10, 110, there being means for the suction of the liquid associated with the ampoule 20 and means of expulsion of the same, the means of suction of the liquid co-operating with a liquid container chamber 24 located in a position axial to the injector 10, 110 and associated with piston means 23, said piston means 23 being associated with spring means 30, the injector 10, 110 filling means comprising means of axial reverse displacement of the piston 23 and of arming of the spring means 30 with consequential suction by depression of the liquid inside the container chamber 24, there being snap disengagement means 31 of the spring means 30, there being at least one non-return valve 49 between the containment chamber 24 and the ampoule 20 as well as a non-return valve 48 between the containment chamber 24 and the expulsion hole 15. <IMAGE>
