Abstract

The inhalation therapy device according to the invention comprises a nebulizer chamber which accommodates an aerosol generator that emits aerosol into the nebulizer chamber. A valve that has a valve seat, a resilient valve member and a valve member positioning means is arranged at an opening of the nebulizer chamber. The valve member positioning means can be moved out of a first position and into a second position so as to position the valve member on the valve seat in such a manner that in the first position, the valve member, in a flow-free state, is positioned on the valve seat in a pre-tensioned manner and in a second position, is spaced apart from the valve seat.
