Patent number: 11815919Abstract: A plural component dispensing system includes a dispensing device, first and second fluid component sources, a system controller, and an operator interface device. The first fluid component source is connected to the dispensing device to deliver the first fluid component to the dispensing device. The second fluid component source is connected to the dispensing device to deliver the second fluid component to the dispensing device. The system controller is connected to regulate operation of the first fluid component source and the second fluid component source to produce a target ratio of the first fluid component and the second fluid component at the dispensing device. The operator interface device is remote from and operatively connected to the system controller. The operator interface device is configured to output system state information received from the system controller and to receive operator input to control an operational state of the system controller.Type: GrantFiled: May 17, 2021Date of Patent: November 14, 2023Assignee: Graco Minnesota Inc.Inventors: Thomas V.

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
