Title: DOSE SETTING AND INDICATOR MECHANISM
Abstract:
An injection device comprising a housing (112), and a dose selector (116) operatively connectable to a dose indicator positioned within the housing. The dose selector and the dose indicator (118, 119) are capable of cooperating to set a dose to be ejected from the injection device. The injection device further comprises a spring (120) capable of storing energy necessary for ejecting the dose from the injection device. The spring is locked to the dose indicator such that a charging force can be transferred from the dose selector to the spring via the dose indicator to increase the energy stored by the spring.
