Abstract

A cleaning diffuser is disposed above a fluff-laden component and receives rinsing fluid for distributing the rinsing fluid to the fluff-laden component to detach fluff and carry it away. The diffuser is constructed to enable a buildup of dynamic pressure in the rinsing fluid and has two feed ducts which extend at a distance from one another in substantially parallel relationship so that rinsing fluid entering the diffuser is divided between the feed ducts. The feed ducts terminate in pockets in a wall at an end of the diffuser and have, relative to their entire duct length, a narrow, three-dimensional transverse mutual connection in the form of a transverse chamber. The diffuser has at least one narrow outlet opening which extends from the three-dimensional transverse connection to a lower side of the diffuser for distributing the rinsing fluid to the fluff-laden component.
