Abstract: A line marker carries a spray nozzle assembly for marking or painting a line on a horizontal surface. The line marker has a hydraulic circuit which includes a reservoir for holding marking liquid therein and a tank for holding water therein. A pump can pump marking liquid through the spray nozzle during a marking mode of operation or water through the spray nozzle during a flush mode of operation. In the marking mode, at least some marking liquid is recirculated back through the reservoir to help keep the marking liquid in the reservoir agitated and mixed. In the flush mode, water is blocked from entering the reservoir and is recirculated back into the water flow from the tank. In the clean out mode, the hydraulic circuit is operated as if in the marking mode, except that the reservoir is rinsed with an external source of water with the rinse water circulating through the hydraulic circuit and back to the reservoir.

Abstract: A turbine assembly for a rotary sprinkler head includes a flow control valve, a turbine housing having a fluid inlet and fluid outlet ports, and a rotor mounted in the housing. The flow control valve is moveable between a closed position and a maximum open position, and is spring biased towards the closed position in which all of the fluid flowing into the sprinkler head initially flows into the turbine assembly. When the flow rate through the sprinkler head is sufficient to open the valve, a portion of the fluid flow passes through the valve to bypass the turbine assembly. As the flow rate continues to increase, the valve opens further until it reaches the maximum open position. Once the valve is opened to a predetermined point, as it opens further, up to the maximum position, the valve also increasingly throttles the fluid outlet ports up to a point short of complete blockage of the outlet ports.
