Also provided is a method for producing a spray cone (58) of a medical irrigation liquid (18), in which a gas pressure is limited using a pressure reduction valve (12), the gas pressure limited by the pressure reduction valve (12) is conveyed through a pressure line (9) to a liquid reservoir (16) of the medical irrigation liquid (18), and the irrigation liquid (18) is pushed out from the liquid reservoir (16) through a nozzle (24, 52) by means of the gas pressure, wherein the spray cone (58) is produced in that the irrigation liquid (18) flows through the nozzle (24, 52).1/2 3836 34 30 26 9 15 14 12 10 9 8 1 2 4 6 24 32 22 Figure 122 1 92 1
