摘要：
The assembly procedure, in which a needleless injector housing (2) is fitted with a series of components forming a circuit containing a pyrotechnic charge initiator and a liquid reservoir includes a stage in which a gas generator cartridge adapted to the nature and/or quantity of liquid to be injected, and the desired injection depth, is inserted from outside the housing directly into the circuit, independently of its components. The housing incorporates a cavity, between the initiator and reservoir, with an aperture to receive the said cartridge, the aperture being sealed from the outside as the cartridge is inserted. The cartridge is in the form of an L-shaped tube that fits between a percussion assembly (3), comprising a percussion unit (30) and spring (31), and a gas expansion chamber.
