Abstract: A piston rod (27) for a spray fluid pump includes an interior pumping chamber (40), one or more channels (50) formed on the exterior of the piston rod, and one or more side bores (32) extending through the piston rod and in fluid communication with the interior piston chamber and one or more channels. The one or more channels (50) extend at least partially axially and are open along a length of the channel. The one or more channels are angled offset with respect to the reciprocation axis for imparting a rotational moment on the piston rod to cause rotation of the piston rod during reciprocation of the piston rod. A spray fluid pump comprising such piston rod is also disclosed.

Abstract: A pump rod has a head extending from a neck, and the head is received within a drive slot of a drive link. The head includes a projection, and has an area smaller than an area of the head. The projection contacts an inner surface of the drive slot. The drive link may include a projection aligned with a centerline of the drive link. The drive link projection contacts a head of the pump rod. The projections provide a reduced contact area between the pump rod and the drive link, thereby reducing any side-loading on the pump rod and increasing a lifespan of the wear parts.

Abstract: A spray roller system for application of architectural paints coating, includes an extension tube, a spray head mounted on a distal end of the extension tube, and the in-line valve with a trigger mounted on a proximal end of the extension tube, and a roller handle removable mounted on the extension tube adjacent the spray head. The spray roller system can spray and back roll a coating on a down stroke and roll on each up stroke. When the roller handle is removed from the extension tube, it can be used to hand roll sensitive wall areas. With the roller handle removed, extension tube, spray head, and in-line valve can be used as a spray extension to apply coatings in hard to reach areas.
