Patent number: 11819868Abstract: A spray gun includes a gun body and valves configured to control flow of material and air through the gun body. A trigger is mounted to the gun body and is disposed relative to the valves such that the trigger actuates the valves in sequence to begin air flow and material flow. A sensor senses when the trigger is in an actuated state and the sensor causes a pump to begin pumping material to the spray gun. Release of the trigger causes the trigger to leave the actuated state. A detent mechanism holes the trigger in a detent state intermediate the actuated state and a resting state. The sensor does not sense the trigger with the trigger in the detent state. The trigger maintains the valves open with the trigger in the detent state.Type: GrantFiled: July 29, 2022Date of Patent: November 21, 2023Assignee: Graco Minnesota Inc.Inventors: Jeremy P. Jurmu, Douglas S. Ryder, Quincy A. Kesti, Robert J. Gundersen, Jeromy D. Horning, Steve J. Wrobel, Chad R. Taszarek

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
