1. An inhalation device for medically active liquids and for generation of an aerosol, comprising:
a housing having at least one reservoir within for storing a liquid and at least one pumping unit with at least one pumping chamber for generation of a pressure inside said pumping chamber, wherein the pumping chamber is fluidically connected with the reservoir via a check valve;
the pumping chamber further comprised of at least one channel disposed therein;
at least one riser pipe at least partially received within the channel of the pumping chamber, the riser pipe having a first end facing the reservoir in said pumping chamber, and a nozzle secured to a second end of the riser pipe, wherein the at least one pumping chamber is adapted to reciprocate relative to the riser pipe;
wherein the riser pipe is fixed to the nozzle and immobile relative to the housing; and
wherein the nozzle has a main axis and at least three ejection channels adapted to eject liquid along respective ejection trajectories, wherein at least one collision point is provided at which at least two of said ejection trajectories intersect with one another.
