    摘要： The present invention relates to a drive mechanism for a drug delivery device for dispensing of a dose of a medicinal product, comprising: a holder for a product-containing cartridge, the cartridge having a piston slidably arranged therein in an axial direction, a piston rod to be operably engaged with the cartridge's piston for dispensing of a dose of the medicinal product, an adjusting assembly adapted to eliminate axial clearance between the piston and the piston rod, wherein the adjusting assembly comprises at least one radially extending spike element for mutually locking in position the piston and the piston rod irrespective of the relative distance between piston and piston rod.

    摘要： The present invention relates to a cartridge for a drug delivery device comprising of a body of substantially cylindrical shape, a piston slidably disposed in the body along two opposite axial directions, along a distal and along a proximal direction, and at least one friction means operably engaged with the piston to generate a pre-defined friction force between the piston and an inside wall of the body, when the piston is displaced relative to the body, wherein in response to an axial displacement of the piston relative to the body in distal direction and in proximal direction, the at least one friction means is adapted to generate respective proximal and distal friction forces that are different in magnitude.
