Abstract (en)
[origin: EP0451615A2] A discharge device with a liquid pump (5) and an air pump (6) has a control valve (15) for the latter lying very close to the discharge opening, the mouth (20) of which opens directly into a terminal duct (16) forming the discharge opening, so that pressure losses are largely avoided. For cleaning, at least in the area of the discharge opening, a control is provided by means of which air continues to be delivered on termination of the liquid delivery. In this way a very fine atomisation is possible with a simple design. <IMAGE>
