Paint roller

摘要

An apparatus is provided for applying fluid material such as paint to a surface. In the illustrative embodiment the apparatus comprises a wheeled carriage which can be moved along a floor or other support surface and the applicator is an absorbent paint roller. The carriage includes a well for receiving a paint pail and also includes a pump and a conduit for delivering paint from the paint pail to the paint roller. At the paint roller the paint is distributed by a manifold having varying sized ports along the length of the paint roller so as to distribute paint onto the paint roller evenly along its length. More specifically the supply conduit delivers paint to the center of the manifold and the paint flows laterally along the length of the manifold and exits onto the applicator through the ports. The central ports are smaller than the end ports and gradually increase in size toward the ends of the manifold to accommodate differences in pressure within the manifold and assure a more even distribution of the paint along the length of the roller.
