    摘要： An accessory cart having a J-shaped frame for removable mounting of a spray gun to convert a conventional airless paint sprayer into a line striper to paint lines on parking lots, curbs, warehouse floors and other pavement surfaces, and which can alternately be used in conjunction with a traditional line striper in cramped spaces or between parked cars, and which is easily converted from a 3-wheeled device to a 2-wheeled device for painting curved lines, and which permits adjustable positioning of the spray gun at a desired location on the cart to optimize the spray pattern in a particular application.

    摘要： Improved method for cleaning a pump, fluid hose, and spray gun is provided by, for example, repeatedly changing the flow rate of the cleaning fluid pumped through the system to generate turbulence or increased turbulence and increased frictional resistance for enhanced cleaning action. A pressure control can cyclically vary the speed of the pump motor and pump connected thereto to generate the turbulence. The pumping cycle can alternate between a first and second power level and at a desired time interval for each speed. With a suitable solvent as the pumped fluid, the turbulence that is generated by the cyclical pumping action causes an increase in the scrubbing action of the solvent to quickly loosen residual material in the fluid passageways.

    摘要： A liquid pumping, handling and spraying system for liquid compositions and especially those liquid coating compositions having a suspension of metal particulate therein which tends to settle out of suspension of metal particulate therein which tends to settle out of suspension quite rapidly and which includes metal particulate having an affinity for adherence to metal surfaces. A fluid supply system is provided which accomplishes continuous agitation of the liquid composition to sprayed to maintain the metal particulate thereof in properly entrained suspension and even distribution with the liquid carrier fluid and which permits the use of low cost, lightweight containers for the liquid supply. A packingless pump is provided for pressurized delivery of the liquid composition from the supply container to a packingless spray gun. The packingless pump achieves pumping of liquid by hydro mechanical deformation of polymer variable volume pump chambers which induce intermittent suction and pressurization of the liquid for pumping and which have externally mounted check valve heads for controlling the flowing of the pumped liquid from the supply container to the spray gun. The packingless spray gun employs a body of resilient polymer which functions as a columnar spring to control the opening and closing movement of a spray valve assembly. Valve seats of the check valve head and spray gun assembly may be of flexible nature to ensure efficient separation of metal particulate therefrom. Metal operational components of the check valve head and spray gun, such as valve stems and valves define outer surfaces composed of titanium to minimize metal particulate adherence thereto.

    摘要： Method and apparatus for recovering leaked fluid or directing fluid flow or propagation through utilization of negative pressure pulses occurring in a pressurized fluid system. The invention has particular application in double acting hydraulic fluid motors where leakage of hydraulic fluid past the output shaft seal may be efficiently collected and redirected into the pressurized hydraulic fluid system through utilization of negative pressure pulses that are developed periodically by fluid direction changes during operation of the hydraulic fluid motor.
