ABSTRACT:
The specification describes an apparatus for providing a fluid under pressure to an exterior surface of an elongate cylinder. The apparatus is comprised of an elongate housing having a fluid collection chamber havingan opening positionable adjacent the exterior surface of the cylinder and an elongate nozzle in the housing which is projected through the opening in close proximity to the exterior surface of the cylinder. The nozzle has a length which is about equal to the length of the cylinder and a width which is less than the diameter of the cylinder. Conduits are connected in fluid flow communication with the nozzle and chamber in order to provide a flow of ink or cleaning fluid to the nozzle for inking or cleaning the cylinder under pressure and to maintain a reduced pressure in the chamber relative to the pressure of fluid exiting the nozzle. The apparatus provides the ability to deliver ink or cleaning fluids under pressure and relatively high velocity to the cylinder for more adequate filling and cleaning of the cylinder without the need for elaborate seals to contain the ink or cleaning fluid within the boundaries of the apparatus during the operation thereof.
