Abstract: An injection device for delivering equal doses of a fluid contained in a reservoir, the device having a housing, and an arming mechanism and a dose delivery mechanism arranged therein, the housing coupled to an enclosure for the reservoir. The arming mechanism includes an axially non-displaceable and rotatable setting sleeve. The setting sleeve is coupled with a spring strained by the rotation of the setting sleeve during arming of the device. The dose delivery mechanism includes a screw ring and a non-rotatable and axially displaceable piston rod within the setting sleeve. The piston rod cooperates with the screw ring so that during arming, the screw ring and the piston rod are immobilized, and during delivery of each dose the piston rod is displaced along the housing due to unwinding of the spring and rotation of the screw ring, the displacement of the piston rod causing the fluid to be discharged from the reservoir.
