A dispensing device (1) for spray cans filled with a flowable product under gas pressure is specified, having a product path (14) which can be closed by a dispensing valve (5) and has a throttle nozzle arrangement which has on its entry side at least one entry channel (23), arranged substantially in a plane running perpendicular to the axial direction, and on its outlet side an outlet channel (22) which runs substantially axially and into which the entry channel opens out substantially tangentially. With a dispensing device of this type, the dispensing flow of the product is to be kept substantially constant irrespective of the degree of filling of the spray can which is pressurised by a gas which is virtually undissolved in the product, in which case blockage of the product flow path is to be prevented in a simple construction. For this purpose, the throttle nozzle opening (11) is arranged in the product path (14) ahead of the dispensing valve (5) in the flow direction. <IMAGE> |
