    • A syringe (114) is received with a housing, the syringe having a bore terminating at a forward end in a hypodermic needle (118) and at a rearward end in a flared opening (210) in which a bung (134a) having a bore (206) surrounded by a skirt (208) is inserted. A drive element (134) has a forward end consisting of a substantially flat annular region (200) that bears upon the skirt of the bung and surrounds a conical middle region (202) that is received in the bore (206) of the bung. An actuator advances the drive element (134) so as to advance the bung and discharge the contents of the syringe through the needle (118). The opening (210) in the rear of the glass syringe is flared by being provided with a radius. The combination of the radius at the opening and the projecting conical middle region of the drive element allows misalignments of the two to be managed during automated assembly.
    • 注射器(114)被容纳有壳体,注射器具有终止于皮下注射针(118)中的前端的孔,并且在扩张开口(210)中的后端处,其中具有孔的孔(134a) (206)被一个裙部(208)包围。 驱动元件(134)具有一个前端,该前端由一个基本平坦的环形区域(200)构成,该环形区域(200)承载在该栓塞的裙部上,并且包围容纳在该膛孔内的锥形中间区域(202)。 致动器使驱动元件(134)前进,从而使注射器的内容物通过针头(118)排出并排出。 玻璃注射器后部的开口(210)通过设置半径而扩口。 开口处的半径与驱动元件的突出的锥形中间区域的组合允许在自动组装期间管理两者的对准。
