Abstract
An assembly for producing aerosol pulses with a valve block (1), which has a breathing channel (2), an air channel (3) which enters the breathing channel transversely, and an aerosol channel (4) which enters the breathing channel transversely and mechanical, electromagnetic or pneumatic control valves (S1, S2, R), for controlling the supply of air and aerosol through the channels in the valve block. The assembly has a flow figure (5) in the breathing channel in the area of the openings of the air and aerosol channels. The longitudinal axis of the air channel also is laterally shifted with respect to the longitudinal axis of the breathing channel so that a tangential flow against the flow figure is achieved and that the longitudinal axis of the aerosol channel is laterally shifted with respect to the longitudinal axis of the breathing channel so that a tangential flow against the flow figure is achieved.
