    • An injection device including casing with a reservoir for an injectable product, an operating button which can be moved relative to the casing in a dosing direction which increases the dosage and in a correcting direction to set a product dosage, a conveying member for delivering the dosage set, a slip coupling comprising a latching element and a co-operating latching element which latch to each other in a latching engagement and couple the operating button to the casing in a positive and non-positive fit in discrete latching positions during a movement in the dosing direction or the correcting direction, and a spring member which opposes the movement of the operating button in at least one of the directions with a spring force, wherein the latching element or co-operating latching element are shaped such that in the latching engagement they offer a lower resistance to the movement in the at least one of the directions than to the movement in the other direction.
    • 一种注射装置,包括具有用于可注射产品的储存器的壳体,可以以增加剂量并且在校正方向上以剂量方向相对于壳体移动的操作按钮,用于设置产品剂量;用于递送剂量的输送构件 设置有滑动联接器,其包括闩锁元件和相互锁定的闩锁元件,所述闩锁元件以锁定接合方式彼此闩锁,并且在所述锁定元件的移动期间将所述操作按钮以正和非正配合联接到所述外壳中的离散闩锁位置 配量方向或校正方向,以及弹簧构件,其弹性力与至少一个方向上的操作按钮的移动相对,其中闭锁元件或配合闩锁元件成形为使得在闩锁接合中 对所述至少一个方向上的运动提供比在另一个方向上的运动更低的阻力。
