US Patent 12017239 Fluid application systems including pressure dampeners

A fluid application system includes a manifold defining an internal passageway for fluid flow therethrough and a plurality of nozzle assemblies connected in fluid communication with the internal passageway. Each nozzle assembly of the plurality of nozzle assemblies includes a body defining a fluid passage, an inlet connected to the manifold for receiving fluid flow into the fluid passage, and a spray outlet for discharging fluid from the fluid passage. Each nozzle assembly also includes an electrically actuated valve fluidly connected between the inlet and the spray outlet and configured to control fluid flow through the fluid passage. Each nozzle assembly further includes a pressure dampener connected in fluid communication with the fluid passage upstream of the electrically actuated valve. The pressure dampener is configured to dampen fluctuations in fluid pressure within the fluid passage.
