| 摘要 |
The present invention relates to a device for impulse ejection of medium, comprising an ejection tube (1) for medium to be ejected therefrom through an ejection end of the ejection tube (1) by way of a propellant in pulsed fashion in an ejection direction (15), a membrane (6) in the area of the ejection end (1), said membrane being elastically deformable during ejection of medium for forming a passage opening (20) for medium, and a nozzle element (9) in the ejection tube (1), said nozzle element being adapted to be movable along the ejection direction between a rest position (9′) and an ejection position (9″), wherein the nozzle element (9) in the ejection position (9″) effects a deformation of the membrane (6) to form the passage opening (20) and in the rest position (9′) effects a slight deformation or no deformation of the membrane (6) and wherein the nozzle element (9) can be brought from the rest position (9′) to the ejection position (9″) when medium is ejected. The present invention further relates to a corresponding method and a membrane (6) for a device for impulse ejection of medium, and a method for increasing the range of an impulse ejection of medium.
