摘要:
Injecting device with dose resetting mechanism enables release energy accumulated in spring means (17) and causes automatically the back movement of an indicating element (16) to its initial position without causing any axial movement of a threaded piston rod (10), said actions being initiated by one movement of a dose setting element (4) in the direction opposite to that when setting a dose. Reset clutch (13) is made as an axially sliding, shaped coupling element moved by means of the dose setting element (4), and moreover this reset clutch (13) is functionally connected with a drive unit destined to co-operate with the spring means (17) in such a way that when this reset clutch (13) is released, said drive unit is disconnected from the spring means (17) retaining the connection of this spring means (17) with the indicating element (16).
