    • The invention relates to an injection device (1), comprising a plunger (3) for moving a plug in a syringe or cartridge, a retainer (7) for the plunger (3), a drive for axially moving the retainer (7) of the plunger (3), and a control device associated with the drive. According to the invention, the plunger (3) or at least a partial element (11) thereof can be moved in relation to the retainer (7) and the retainer (7) can be moved in relation to the plunger (3) or a partial element (11) thereof over a limited distance against a preloading force, a sensor device (27) that senses the position of the plunger (3) or of the at least one partial element (11) thereof in relation to the retainer (7) is provided, which sensor device comprises at least one sensor element (29), which interacts with the control device, and the control device is designed in such a way that the advancing speed of the retainer (7) of the plunger (3) is at least reduced when the sensor element (29) is activated.
    • 本发明涉及一种注射装置(1),其包括用于移动注射器或药筒中的塞子的柱塞(3),用于柱塞(3)的保持器(7),用于轴向移动保持器(7)的驱动器 柱塞(3)以及与驱动器相关联的控制装置。 根据本发明,柱塞(3)或其至少一个部分元件(11)可相对于保持器(7)移动,并且保持器(7)可相对于柱塞(3)或 其部分元件(11)相对于预加载力在有限的距离上;传感器装置(27),其感测柱塞(3)或其至少一个部分元件(11)相对于保持器(7)的位置 ),所述传感器装置包括与所述控制装置相互作用的至少一个传感器元件(29),并且所述控制装置被设计为使得柱塞(3)的保持器(7)的前进速度, 在传感器元件(29)被激活时至少减小。
