A needleless injector for injecting medication through the skin of a patient includes a vial which holds a volume of liquid medication. The vial includes a vial piston which moves to force the liquid medication out of the vial. A power mechanism applies force to the vial piston. The power mechanism includes a power piston which has a plurality of ratchets. A spring is positioned to apply force to the power piston. A trigger engages the ratchets on the power piston to hold the power piston in place against the force applied by the spring. The trigger selectively releases the power piston so that the power piston moves in response to the force applied by the spring. The power piston applies the force to the vial piston to cause the vial piston to force the liquid medication out of the vial. A cocking mechanism applies force to the power piston to move the power piston against the force of the spring to engage the ratchets. A travel adjustment mechanism is moveable to position the spring within the power mechanism to control the movement of the power piston and to thereby control the volume of liquid ejected from the vial.
