Claim Text:
1. A device for impulse ejection of a medium, the device comprising: an ejection tube for the medium from which the medium can be driven out by a propellant impulse-like in an ejection direction through an ejection end of the ejection tube; a membrane provided in an area of the ejection end of the ejection tube, the membrane having a plurality of curved slits in an un-deformed configuration which extend radially outward from a center of the membrane, and the membrane being elastically deformable to form a passage opening for the medium during ejection of the medium; and a nozzle element operatively coupled to the ejection tube to move along the ejection direction between a rest position and an ejection position and to enable the medium to interact with the membrane during ejection to improve range and stability of the ejected medium, wherein the nozzle element in moving to the ejection position causes deformation of the membrane to form the passage opening and in the rest position produces smaller or no deformation of the membrane, and wherein the nozzle element during ejection of the medium can be brought from the rest position to the ejection position.
