    摘要： A field marking system includes a marking solution storage tank, a mixing volume fluidly connected to the storage tank and configured to mix marking solution from the storage tank with pressurized air, a nozzle fluidly connected to the mixing volume and an engine including a turbocharger. The turbocharger supplies pressurized air to at least one of the solution storage tank and the mixing volume. In one exemplary embodiment, the turbocharger supplies pressurized air to both the solution storage tank and the mixing volume. The marking system additionally includes a valve connected between the solution storage tank and the mixing volume and a control circuit coupled to the valve. In one exemplary embodiment, the control circuit generates a control signal such as the valve modulates based upon the control signal to vary production of marking medium. In one exemplary embodiment, the marking system further includes a vent valve connected to the solution storage tank and a fill valve connected to the solution storage tank. The vent valve and the fill valve are configured such that the fill valve cannot be opened until the vent valve is opened. In one exemplary embodiment, the field marking system is configured as part of a sprayer.

    摘要： A boom assembly includes a central support, a first wing pivotably coupled to the central support so as to rotate about a first axis, a first cylinder-piston assembly having a first end pivotably coupled to the support, a second end pivotably coupled to the first wing at a first pivot point for rotation about a second axis on a first side of the first axis, and a second cylinder-piston assembly having a first end pivotably coupled to the support and a second end pivotably coupled to the first wing at a second pivot point for rotation about a third axis on a second side of the first axis. Extension and retraction of the first and second cylinder-piston assembly applies varying opposing torque to the first wing depending upon an angular orientation of the first wing about the first axis. In one exemplary embodiment, the first piston-cylinder assembly includes a cylinder coupled to one of the support in the first wing having a first chamber proximate the first wing and a second chamber distant the first wing, a piston disposed in the cylinder separating the first and second chambers and a rod coupled to the piston and the other of the support in the first wing. The boom assembly additionally includes a source of fluid and a fluid line in communication between the first chamber and the source of fluid. The fluid line is configured to restrict fluid flow to a maximum first rate from the first chamber to the fluid source as a volume of the first chamber is reduced. The boom assembly preferably includes a one-way valve in the fluid line preventing fluid flow from the source of fluid to the first chamber at a second maximum rate greater than the first maximum rate. In another exemplary embodiment, the boom assembly is provided as part of sprayer, wherein the first wing carries a plurality of spray nozzles fluidly connected to a fluid reservoir.
