摘要： A spray-type dampening water supply apparatus having a spray unit whose nozzles (10, 20, 30, 90) are protected against adhesion of any foreign matter to the nozzle surfaces and in which at least orifices (13, 23, 33, 93) of the nozzles (10, 20, 30, 90) can be easily cleaned out. Each nozzle of the spray has a guide surface (1, 2, 3) slanting from an upstream outer peripheral edge toward a downstream central orifice. A partition (40, 50, 60) of the spray is disposed downstream of the nozzle assembly and has a plurality of apertures (41, 51, 61) confronting the respective nozzles. The spray is equipped with means (70) for opening and closing the apertures (41, 51, 61) of the partition (40, 50, 60).
