A dump hopper for a road sweeper includes a dump door 20, a debris guide chute 42, and an actuating mechanism for pivoting the dump door and debris chute between travel and dumping positions. The dump door is sandwiched between a hopper 11 and the guide chute in the travel position and seals a debris discharge opening 12 of the hopper. A pair of hydraulic cylinders 30 are pivotally connected to the dump door and the guide chute and cooperate with cam and cam followers to hold the dump door in a sealed relationship with the debris discharge opening until the debris guide chute has been fully deployed. Also claimed is a fluid control system. |
