Patent number: 11732708Abstract: 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.Type: GrantFiled: November 17, 2022Date of Patent: August 22, 2023Assignee: Graco Minnesota Inc.Inventors: David J. Thompson, Christopher A. Lins, Andrew J. Kopel, Glen W. Davidson, Chad R. Taszarek, Chris W. Sydow, William M. Blenkush, Steve J. Wrobel
