Patent number: 11931765Abstract: A spray gun adapter establishes fluid communication between a fluid pump of a handheld airless spray gun and an applicator accessory. The adapter comprises an adapter body, a head attached to the adapter body, and a protrusion. The adapter body comprises an upper portion, a lower portion, a radial inlet located in a sidewall of the adapter body between the upper and lower portions, and an adapter bore having a first diameter in fluid communication with the radial inlet. The head comprises a cavity in fluid communication with the adapter bore and having a second diameter larger than the first diameter, an adapter outlet located in the upper portion of the adapter body and in fluid communication with the cavity, and a handle extending radially from the head. The protrusion extends radially from the adapter body between the upper and lower portions of the adapter body.Type: GrantFiled: June 17, 2021Date of Patent: March 19, 2024Assignee: Graco Minnesota Inc.Inventors: Diane L.

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

Patent number: 11738358Abstract: A fluid sprayer includes a pump and an electrostatic module configured to provide an electrostatic charge to spray fluid. The electrostatic module is electrically connected to a conductive component of the fluid sprayer, such as a fluid displacement member, fitting, cylinder, or spray tip, to charge the spray fluid via the conductive component. The fluid is electrostatically charged prior to exiting the fluid sprayer.Type: GrantFiled: February 18, 2021Date of Patent: August 29, 2023Assignee: Graco Minnesota Inc.Inventors: Robert W. Kinne, Mark E. Ulrich, Diane L. Olson
