    摘要： The piston rod arrangement is in an assembled state before use and comprises a piston rod, a bung, which is intended to be driven by the piston rod, a body member, and a drive member. The piston rod is threadedly engaged with the body member, and the drive member is threadedly engaged with the piston rod and movable relative to the body member. A mechanism is provided defining unit steps of movement of the drive member and corresponding unit steps of movement of the piston rod. The piston rod is arranged in contact with the bung or at a distance from the bung that is less than a distance of one corresponding unit step of movement. When the piston rod, the bung and the drive member are assembled in the body member, the piston rod is advanced with respect to the body member towards the bung, until the piston rod is stopped by the bung. The drive member is rotated until the piston rod begins to advance again and the drive member is then stopped, and the piston rod is fixed at or near the position obtained.

    摘要： The present disclosure pertains to an assembly for a drug delivery device having a housing part, a piston rod displaceable relative to the housing part, a first sleeve member and a second sleeve member. First and second sleeve members are coupled to the housing part. In an initial state of the assembly the first sleeve member is movable from an initial position to a second position relative to the second sleeve member which allows the piston rod to axially travel from an initial position to a predetermined second position such that the assembly is in a primed state. Moreover, in the primed state of the assembly, with the first sleeve member being in the second position relative to the second sleeve member, first and second sleeve members are permanently rotationally and axially locked to each other by a first engagement feature such that first and second sleeve members together form a sleeve.

    摘要： The present disclosure concerns a drive mechanism for a drug delivery device, having a first and a second state and comprising a piston rod configured to be moved in a distal direction when the drive mechanism is operated and an adjusting member, wherein the adjusting member is rotatable relative to a body of the drug delivery device in the first state of the drive mechanism and is prevented from rotating relative to the body in the second state of the drive mechanism, and wherein the adjusting member is configured to adjust an axial position of the piston rod in the first state of the drive mechanism.
