The nozzle defines a fluid outlet that is in fluid communication with the fluid chamber. The valve element has an upper portion outside of the fluid chamber that is adapted for contact with the drive pin, and the biasing element is configured to apply a spring force to the valve element. The valve element is configured to cause a droplet of the fluid to be jetted from the fluid outlet when the valve element is moved in the direction toward the nozzle.

Abstract: A can coating machine control system includes a coating control signal that functions as a go/no-go signal based on a plurality of monitored conditions such as can in position, vacuum pressure, gun in position, guard in position and speed condition. Local pressure regulation of the coating material in the spray gun is provided along with optional control of the material temperature. Local pressure regulation allows for optional spray weight control based on a wrap number derived from speed and gun spray durations. A CAN to CAN network buffer is provided as well for primary network isolation. A gun control circuit may be used to select specific gun drive signals and to adjust gun drive signals based on real-time feedback of the actual spray duration.

The spool is rotatable with respect to said outer body between a first position in a first flow configuration, and a second position in a second, different flow configuration.

Abstract: A flow shifter baffle for mixing a fluid flow having at least two components, a static mixer and method of mixing. The flow shifter baffle includes a double divider wall element adjacent to a leading edge and a plurality of occluding walls coupled to the double divider wall element. The double divider wall element includes first and second generally parallel walls which extend across the entire transverse flow cross-section. The double divider wall element is configured to divide the fluid flow into a central flow portion and first and second peripheral flow portions. This division of the fluid flow using the double divider wall element and the plurality of occluding walls improves the mixing of separate components by producing a greater number of layers with less jumbling of the layers, when a layered composition of multiple components is delivered into the flow shifter baffle.

The nozzle also includes an annular valve seat that is configured to contact the valve tip when the valve stem moves in the downstream direction, and a resilient annular portion that extends from the nozzle body and is adjacent to the annular valve seat. As the valve stem moves in the downstream direction, the resilient annular portion contacts the valve tip, flexes radially outwards, and thereby forms a sealing engagement with the valve tip, to avoid undesirable additional dispensed volumes that may be caused if the valve tip recoils away from the valve seat following initial contact of these elements.
