Abstract
(EN)
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.
