摘要： The present invention relates to a dispensing speed control mechanism for use in an injection device. The injection device may have a housing (10, 30, 40; 40′; 40″; 40′″) and a drive member (70), which is driven by a power reservoir (100, 100′) and axially movable between a dose setting position, in which the drive member (70) is rotationally constrained to the housing (10, 30, 40; 40′; 40″; 40′″), and a dose dispensing position, in which the drive member (70) is rotationally de-coupled from the housing (10, 30, 40; 40′; 40″; 40′″). The speed control mechanism comprises friction means (42) for retarding the drive member (70) during dose dispensing depending on the axial position of the drive member (70). Further, the invention relates to an injection device with such a dispensing speed control mechanism.

摘要： The present invention relates to a handheld automatic injection device comprising a housing (10, 30, 40; 40′), a piston rod (80) located within the housing (10, 30, 40; 40′), a drive member (70) permanently coupled to the piston rod (80), a dose setting member (50), which during dose setting rotates relative to the housing (10, 30, 40; 40′) in a first direction and which during dose dispensing rotates relative to the housing (10, 30, 40; 40′) in a second opposite direction, and a power reservoir (100) for driving the drive member (70). The drive member (70) is axially movable between a dose setting position, in which the drive member (70) is rotationally constrained to the housing, and a dose dispensing position, in which the drive member (70) is rotationally decoupled from the housing (10, 30, 40; 40′). The power reservoir comprises a reverse wound flat spiral spring (100) having a first end attached to a first spool (101) and a second end attached to a second spool (102), with one of the spools (102) being coupled to the drive member (70).

摘要： The present invention relates to a pen type drug delivery device having a dose setting limiter mechanism. The mechanism comprises a housing (10, 30, 40; 40′), a dose setting member (50), which during dose setting rotates relative to the housing (10, 30, 40; 40′) in a first direction and which during dose dispensing rotates relative to the housing (10, 30, 40; 40′) in a second opposite direction, and a limiting element (60) limiting the rotational movement of the dose setting member between a zero dose position and a maximum dose position. The limiting element (60) is rotationally constrained but axially displaceable relative to one of the housing (10, 30, 40; 40′) or the dose setting member (50) and is movable helically (53) relative to the other of the housing (10, 30, 40; 40′)or the dose setting member (50). These movements have end stops (54, 55) limiting the relative movement of the limiting element (60) and thus the dose setting member.
