Abstract The disclosure provides driver components and methods of operating same that provide a reduced form factor for pen-type injection devices. In particular, various multi-piece telescoping plunger rod configurations are disclosed that can be implemented within pen-type injection devices to achieve such improvements. Driver components replace a single plunger rod having fixed length with telescoping pieces that are controlled to at least partially extend axially to dispense fluid from the reservoir or cartridge. L'invention concerne des composants d'entraînement et leurs procédés de fonctionnement qui fournissent un facteur de forme réduit pour des dispositifs d'injection de type stylo. En particulier, l'invention concerne diverses configurations de tige de piston télescopique en plusieurs parties qui peuvent être mises en oeuvre à l'intérieur de dispositifs d'injection de type stylo pour obtenir de telles améliorations. Les composants d'entraînement remplacent une tige de piston unique de longueur fixe par des pièces télescopiques qui sont commandées pour se déployer au moins partiellement dans le sens axial afin de distribuer le fluide depuis le réservoir ou la cartouche.
