Summary: | The invention relates to a pen-type injector comprising a housing (2, 2', 2", 2"'); a piston rod (32, 32', 32") having a screw thread; an insert (14, 14', 14"') located in the housing (2, 2', 2", 2"') and through which the piston rod (32, 32', 32") may rotate; a dose dial sleeve (50, 50', 50", 50"') rotatable with respect to the housing and the insert; and a drive sleeve (60, 60', 60") which is axially displaceable with respect to the housing. The maximum angular displacement of the dose dial sleeve with respect to the housing is determined by abutment of a radially directed lug (100) on the dose dial sleeve (50, 50', 50", 50"') with a catch means (102) on the insert (14, 14', 14"'). The invention relates to a method for assembling a pen-type injector, too. |
