Ejection device for the high-pressure ejection of a liquid
First Claim
1. An ejection device (1) for the high-pressure ejection of a liquid or a liquid containing solid particles, comprising a pressure chamber (13) wherein the liquid is received, which opens into an ejection opening (11) and is delimited by a working piston (5) which, upon application of an impact on its end facing away from the pressure chamber, is capable of transmitting a compression wave by which at least the pressure chamber-facing end of the working piston (5) is displaceable by a predetermined displacement stroke into the pressure chamber (13) so that the volume thereof is reduced, with the reduction in volume of the pressure chamber (13) being significantly smaller than the volume of the pressure chamber (13);
- and a drive member (24) which is capable of generating the impact, characterized in that the working piston (5) is progressively displaced into the pressure chamber (13) by the repeated application of impacts, with the distance of each single displacement being defined by the predetermined displacement stroke.

Abstract
An ejection device 1 for the high-pressure ejection of a liquid or a liquid containing solid particles, comprising a pressure chamber 13 to accommodate the liquid therein, which opens into an ejection opening 11 and is delimited by a working piston 5. The working piston 5 is, upon application of an elastic impact on its end facing away from the pressure chamber 13, capable of transmitting a compression wave which may displace the pressure chamber-facing end of the working piston 5 by a predetermined displacement stroke into the pressure chamber 13 so that the volume thereof is reduced. The reduction in volume of the pressure chamber 13 is signicantly smaller than the volume of the pressure chamber 13. The ejection device 1 further comprises a drive member 24 capable of generating the elastic impact, and is designed such that the working piston 5 is progressively displaced into the pressure chamber 13 by the repeated application of elastic impacts, with the distance of each single displacement being defined by the predetermined displacement stroke.
