Patent number: 10239072Abstract: A grounding dissipation unit for a paint delivery apparatus for delivering paint is disclosed. The paint delivery apparatus includes a first paint line for carrying paint from a canister, a second paint line for carrying paint to an ionizing applicator for electrically charging paint, a first water line for carrying water to a grounding source, a second water line carrying water to the grounding dissipation unit, and a third water line for carrying water to a dump. The grounding dissipation unit includes a core made of an electrically conductive material. A paint bore in the core connects the paint lines, and a water bore in the core connects to the water lines to ground the system. The paint bore and water bore do no intersect within the core.Type: GrantFiled: September 12, 2016Date of Patent: March 26, 2019Assignee: Honda Motor Co.

Patent number: 9366372Abstract: In an electrostatic coating apparatus, an electrically conductive coating material is supplied through a coating material supplying path to a coating gun to which a high voltage is applied. The electrostatic coating apparatus is provided with an insulating and separating valve capable of electrically insulating and separating the coating material supplying path into an application side in which the high voltage is applied and a non-application side. The insulating and separating valve is provided with a female coupling member having a first connecting portion and a male coupling member having a second connecting portion. A supplying hole for supplying a cleaning fluid to the first connecting portion and the second connecting portion and a discharging hole for discharging the cleaning fluid supplied to the first connecting portion and the second connecting portion are provided on one of the female coupling member disposed on the non-application side and the male coupling member.Type: GrantFiled: April 4, 2014Date of Patent: June 14, 2016Assignee: HONDA MOTOR CO., LTD.Inventors: Daisuke Nakazono, Hiroki Matsunaga, Masashi Honma, Norihiko Sudo
