Abstract: The present invention relates to a drive mechanism for a drug delivery device and to a respective drug delivery device, wherein the drive mechanism comprises: —an elongated housing (20) extending in an axial direction (1, 2), an actuation member (30) rotatably supported on the housing (20) for setting of the dose, —a last dose sleeve (110) directly rotatably engaged with the actuation member (30) and having at least one stop (112, 114), a last dose member (120) threadedly engaged with the last dose sleeve (110), further being rotatably fixed to the housing (20) and being operable to engage with the at least one stop (112, 114) to limit a rotation of the last dose sleeve (110).

Abstract: The present invention relates to a drive mechanism of a drug delivery device for dispensing of a dose of a medicament, the mechanism comprising: —a housing (20), —a piston rod (120) extending in an axial direction (1, 2) to operably engage with a piston (14) of a cartridge (12), —a drive sleeve (90) rotatably supported in the housing (20), at least partially enclosing the piston rod (120), the drive sleeve (90) is operably releasable from the piston rod (120) for setting of a dose and the drive sleeve (90) is operably engageable with the piston rod (120) for dispensing of the dose, —a dose limiting member (130) threadedly engaged with the drive sleeve (90), rotatably locked to the housing (20) and being displaceable in axial direction (1, 2) in response to a rotation of the drive sleeve (90) relative to the piston rod (120), —at least one stop member (124) provided on the piston rod (120) to engage with the dose limiting member (130) for impeding a further displacement of the drive sleeve (90) relative to the

Abstract: Drive Mechanisnn of a Drug Delivery Device The present invention relates to a drive mechanism of a drug delivery device for dispensing of a dose of a medicament, the mechanism comprising: —a housing (30) extending in an axial direction (1, 2), —a piston rod (90) to operably engage with a piston (16) of a cartridge (14) to displace the piston (16) in an axial distal direction (1), a last dose sleeve (100) rotatably supported in the housing (30) and being selectively engageable with a dose setting mechanism for setting of a dose, —a last dose member (105) threadedly engaged to the housing (30), rotatably locked to the last dose sleeve (100) and axially displaceable relative to the last dose sleeve (100).
