Abstract: An integrated brake spider and mounting bracket arrangement for a drum brake includes a brake spider with a spider mounting section, having openings through which fasteners may pass to secure the brake spider to an axle flange of a vehicle. The spider is also provided with a base section having an attachment surface for a bracket, and the bracket is secured by way of a metal fabrication process to the attachment surface of the base section and to actuator support structure adapted to support an actuator for the drum brake.

Abstract: A common rail fuel system, primarily including a high-pressure fuel pump, a rail, fuel injection nozzles, and an electronic control system, is disclosed. A substantially constant fuel pressure is maintained within the rail by the fuel pump under the direction of the electronic control system. The pressurized fuel is communicated to the fuel injection nozzles, which are also under the direction of the electronic control system, thereby providing fuel at injection pressure immediately upon the actuation of the fuel injection nozzles by the electronic control system. The pump incorporates leakage fuel during each stroke without the necessity of rerouting the leakage fuel through a primary supply. This reduces the total amount of fuel pumped and improves metering accuracy.

Abstract: A common rail fuel system is described which consists primarily of a high-pressure fuel pump, nozzles and a rail or rails having a substantially constant rail pressure situated between the fuel pump and the nozzles, the necessary connecting fuel lines and electronic control system. The pump is constructed to add leakage fuel to each stroke output without the necessity for routing this leakage fuel through the primary supply. This reduces the total amount of fuel pumped and improves metering accuracy.
