Abstract: A fuel injector which has check valve that is hydraulically controlled by a control fluid. A volume of fuel is pressurized within a fuel chamber of the injector by an intensifier. The check valve controls the flow of fuel from the fuel chamber through at least one nozzle opening of a valve body. The flow of control fluid is controlled by a control valve which can move between a first position and a second position. When the control valve is at its first position, the control fluid creates an hydraulic force which moves the check valve to a closed position. When the control valve is at its second position, the control fluid moves the check valve to an open position to allow the pressurized fuel to be ejected or sprayed from the nozzle opening(s). The intensifier can also be hydraulically controlled by a control valve.

Abstract: A feed line assembly includes adjacent running or coaxial delivery and return conduits for transferring asphalt between a spray bar and a pump and tank of an asphalt distributor. The coaxial feed line assembly provides for one directional flow in each of the feed lines between the spray bar and the asphalt tank/pump. The circulating system can be operated in spraying and circulating modes. Asphalt flows through the delivery conduit to the spray bar and out through nozzles in the spraying mode and asphalt flows from the delivery conduit through the spray bar and is returned through the return conduit in the circulation mode. Asphalt is substantially static in the return conduit during the circulation mode. The coaxial feed line assembly serves as a heat exchanger to transfer heat from the delivery conduit to the return conduit and thereby prevent freezing of substantially static asphalt in the return conduit during spraying mode.
