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: 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: 11806742Abstract: Various embodiments concern a sprayer having a blower that outputs a HVLP flow of air into a hose, the hose connecting with a spray gun. A pressure sensor measures pressure of the HVLP air within the hose via a tube that branches from a fitting to which the hose connects. If the sensor indicates that the pressure level has increased above a threshold amount, indicating that the trigger of the spray gun is not being actuated, then power output to the blower is reduced (e.g., stopped). HVLP air is trapped within the hose by two valves when the trigger is not actuated. When the sensor indicates that the pressure level has decreased, corresponding to release of the trapped HVLP air into the gun for spraying by actuation of the trigger, power to the blower is increased (e.g., resumed).Type: GrantFiled: May 23, 2019Date of Patent: November 7, 2023Assignee: Graco Minnesota Inc.Inventors: John M. Svendsen, Diane L. Olson
