Abstract (en)
[origin: EP0627268A2] The liquid is fed by a piston pump (6) to a nozzle device (16) and for spraying is driven through the nozzle device (16) by the pump pressure. The liquid feed to the nozzle device (16) is pressure-relieved by a pressure-release valve (28) just before the end of a spraying period in such a way that the liquid (4) to be sprayed is sprayed until the end of the intended spraying period by the liquid pressure prevailing in the line system. Only at the end of the spraying period is the liquid feed also cut off or interrupted. By the partial pressure release of the liquid (4) before the expiry of the spraying period, subsequent dripping or subsequent spraying after the expiry of the spraying period is avoided. <IMAGE>
