DOSING MECHANISM FOR AN INJECTION DEVICE FOR ADMINISTERING A PRODUCT

摘要

A dosing mechanism for an injection device includes a dose-setting element with a first element coupled thereto, which, during dose setting, is rotatable relative to a second element about a main rotation axis in a first direction and, during dose discharge, is fixed in rotation relative to the second element. The first and the second elements are coupled via a sleeve-shaped stop element, which forms a stop abutment. The dosing mechanism includes a stop, and the stop abutment, during the rotation of the first element in the first direction, executes a movement to a stop position where the stop abutment strikes the stop and prevents rotation of the first element relative to the second element in the first direction of rotation. The sleeve-shaped stop element is rotatable about a secondary rotation axis, which is offset parallel to or offset at an angle to the main rotation axis.

1. A dosing mechanism for an injection device, comprising:
a dose-setting element coupled to a first element, which, during a dose setting, is rotatable relative to a second element about a main rotation axis in a first direction of rotation and, during a dose discharge, is fixed in rotation relative to the second element, wherein the first element and the second element are coupled via a sleeve-shaped stop element, which forms a stop counter abutment and which surrounds at least one of the first element or the second element; and a stop abutment, wherein the stop counter abutment, during a rotation of the first element in the first direction of rotation moves to a stop position in which the stop counter abutment strikes the stop abutment and prevents the rotation of the first element relative to the second element in the first direction of rotation, and wherein the sleeve-shaped stop element is rotatable about a secondary rotation axis that is offset parallel to or offset at an angle to the main rotation axis.
