Publication number: 20040040988Abstract: A system for dispensing coating material includes a source of coating material to be dispensed and a device for dispensing the coating material. The coating material is provided from the source under pressure to the device. The device includes a body having a passageway therethrough. A valve includes a valve seat provided in the passageway and a valve member for engaging the valve seat to close the valve and moving away from the valve seat to open the valve. In one embodiment, the valve seat and valve member are so dimensioned that when the valve member is against the valve seat, a portion of the valve member facing the valve seat is exposed to the pressurized coating material. In another, the valve seat, a downstream-most portion of the valve member, and a shoulder on the valve member are so dimensioned that the shoulder isolates the downstream-most portion from the liquid under pressure when the downstream-most portion is against the valve seat.Type: ApplicationFiled: August 30, 2002Publication date: March 4, 2004Inventors: Kevin L.

Patent number: 5632448Abstract: A system for atomizing and dispensing powder comprises a fluidized powder bed for entraining the powder fluidized in a bearing air stream, a dispenser, and a motor for rotating the dispenser. The dispenser has a somewhat bell-shaped interior. The motor has an output shaft having a first passageway extending lengthwise thereof. A feed tube extends through the first passageway. The fluidized powder is fed to an end of the feed tube passageway remote from the dispenser to be supplied through the feed tube to the interior as the motor rotates the dispenser. A diffuser is mounted within the interior. A discharge slot is defined between the dispenser and an edge of the diffuser. The feed tube is mounted so that it does not rotate with the output shaft. The diffuser includes a back side facing the interior and bounded by the edge. The back side includes a generally part-spherical concavity into which the fluidized powder is directed from the feed tube.Type: GrantFiled: January 25, 1995Date of Patent: May 27, 1997Assignee: Ransburg CorporationInventors: Kevin L.
