Abstract
A paint roller assembly for a pressurized paint supply system including a hollow roller arm, a delivery tube within the roller arm for receiving pressurized coating material such as paint therethrough, the tube terminating in a horizontally disposed end portion, a circular flange mechanically coupled to the roller arm inwardly of the end portion to prevent relative rotation therebetween, an annular sealing member received over the end portion and arranged to abut the circular flange while permitting relative rotational movement therebetween, a cylindrical roller core having one end received on the end portion, the core having an axially extending relatively shallow groove at its periphery along a major portion of its length, the roller core being recessed at the discharge end of the end portion to provide a sump therein of greater depth than the groove and communicating with the groove. Distributor means are positioned in the groove and have spaced apertures therealong to permit paint to flow from the groove into a perforated paint roller cover positioned over the roller core.
