An inhaler for delivery of a medicament by inhalation includes an inhaler body for receiving a canister having a dispensing valve. A drive mechanism is provided for driving the canister from a rest position in which the valve is closed to an actuating position in which the valve is open. A resetting mechanism is provided for resetting the drive mechanism. A return mechanism is provided for returning the canister from the actuating position to the rest position, wherein the return mechanism comprises a damping system that is configured to enable the canister to automatically return from the actuating position to the rest position within a predetermined time period. A method of operation of an inhaler is also disclosed.

Inhaler

An inhaler for delivery of a medicament by inhalation is disclosed. The inhaler comprises a dispensing mechanism, the dispensing mechanism being configured to dispense a dose of medicament on actuation. The inhaler further comprises a dose counting mechanism comprising a counter and a translating member. The translating member comprises a pawl. The counter comprises a first count wheel, a second count wheel and an intermediate wheel engaged with the second count wheel and in selective engagement with the first count wheel. When the inhaler is fired to dispense a dose of medicament, the dispensing mechanism moves the translating member in a substantially linear direction. The pawl thus rotates the first count wheel, and as the first count wheel rotates, the intermediate wheel is selectively engaged thereby selectively rotating the second count wheel to count the doses of the inhaler.
