Patent number: 8613400Abstract: A nozzle assembly that produces a cone-shaped spray pattern of entrained liquid droplets is disclosed. The nozzle includes an ultrasonic atomizer for atomizing a liquid on an atomizing surface located at the end of an atomizing stem. The nozzle assembly is supplied pressurized air that is directed to the atomizing surface by intercommunicating ports, chambers and/or channels. To provide the cone-shaped spray pattern, the ports, chambers and/or channels cause or direct the pressurized gas to rotate about the atomizing stem. When the rotating pressurized gas exits the nozzle assembly via proximate the atomizing surface, atomized liquid droplets become entrained in the gas. The rotating pressurized gas propels the droplets forward and moves at least some droplets circumferentially outward in the cone-shaped spray pattern. In various embodiments, the pressure of the gas can be adjusted to control the size and shape of the cone-shaped pattern and the distribution of droplets.Type: GrantFiled: November 19, 2008Date of Patent: December 24, 2013Assignee: Spraying Systems Co.Inventors: Daniel J.

Patent number: 8297530Abstract: A spray nozzle assembly that utilizes ultrasonic atomization techniques to atomize a liquid into a cloud of small or fine droplets is disclosed. The nozzle assembly also can use various air or gas atomizing technologies to propel the generally directionless droplet cloud toward a surface or substrate to be coated. The propelled droplet cloud may at this state have a conical or cone-shaped spray pattern. Additional air or gas atomizing technologies can be utilized to shape the propelled droplet cloud into a flattened fan-shaped spray pattern that can be usable in various industrial applications. The shape of the spray pattern and the distribution of droplets within the pattern can be adjusted by manipulation of the gas pressure used in gas atomization.Type: GrantFiled: September 19, 2008Date of Patent: October 30, 2012Assignee: Spraying Systems Co.Inventors: Daniel J.

Patent number: 6899288Abstract: A spray bar having a plurality of laterally spaced nozzles mounted in a row on a header block for discharging a row of liquid spray patterns, and a method of manufacture. The spray bar header includes a plurality of separate plates, each formed with a plurality of nozzle-receiving apertures and with one or more faces of adjacent interfacing plates being formed with grooves which define fluid passages for the supply liquid, atomizing and nozzle-actuating air, and heating fluid. The plates preferably are electroplated/electropolished for thorough and efficient cleaning upon disassembly.Type: GrantFiled: January 22, 2002Date of Patent: May 31, 2005Assignee: Spraying Systems Co.Inventors: Daniel J. Filicicchia, Michel R. Thenin, Robert L Trottier

Patent number: 6827289Abstract: A liquid spraying system having a spray head and a recirculating liquid supply system for directing pressurized supply liquid to the spray head with a portion of the liquid being directed from the spray head as a discharging spray and a portion of the supply liquid exiting the spray head as a return liquid. The liquid supply system includes two separate selectively pressurizable liquid containable tanks each having a respective fluid conduit coupled to the spray head. The liquid supply system has (1) a first cycle of operation in which the first tank is pressurized and the second tank is depressurized so that pressurized liquid is supplied from the first tank to the spray head and return liquid is directed to the second tank, and (2) a second cycle of operation in which the second tank is pressurized and the first tank depressurized so that liquid is supplied to the spray head from the second tank and return liquid is directed to the first tank.Type: GrantFiled: March 24, 2003Date of Patent: December 7, 2004Assignee: Spraying Systems Co.Inventors: Daniel J.

Patent number: 4738401Abstract: A quick disconnect nozzle assembly having a nozzle body, an annular sealing member and a nozzle tip with a socket in the body for receiving the tip and having a pair of chord-like lugs with upstream facing camming surfaces for engaging downstream facing camming recesses in a pair of radially extending shoulders on the nozzle tip to cam the tip axially into sealing engagement with the annular sealing member as the nozzle tip is inserted in the socket and rotated therein. Preferably the socket includes diametrically opposed lugs and the tip has a pair of cooperating shoulders and recesses and at least one radially extending stop adapted to engage an abutment in the base of the socket when the tip is rotated into proper position. The tip may include a swirl imparting vane and have an outer protective sleeve with longitudinal ribs to facilitate rotating the tip by hand.Type: GrantFiled: February 24, 1987Date of Patent: April 19, 1988Assignee: Spraying Systems Co.Inventor: Daniel J.

Patent number: 4438884Abstract: The invention comprises a quick disconnect nozzle including a nozzle body and a nozzle tip, wherein the nozzle body may be connected to a source of fluid and the nozzle tip is separable from the body by a single twist type action, yet the nozzle may be securely locked in the body by an interlocking engagement between the nozzle and body that is engaged and disengaged by relative twisting of the two parts. The locking action is obtained by the engagement of cooperative elements on the two parts including oppositely disposed undercut shoulders on the nozzle body and a pair of rounded projections on the nozzle tip which are engaged under the opposing shoulders by the relative twisting action. The interlocked relationship is maintained by a combination sealing member and pressure device that effectively seals the connection between the nozzle body and tip and exerts pressure therebetween to secure the locked connection.Type: GrantFiled: November 2, 1981Date of Patent: March 27, 1984Assignee: Spraying Systems CompanyInventors: Edward J. O'Brien, Gary A. Paulsen, Daniel J. Filicicchia
