Patent ID: 7574988

Claim:
A pressurized fluid-delivery apparatus comprising: a frame; an engine supported by the frame, the engine including a rotatable member; a pump driven by the engine to discharge a pressurized fluid; an engine starter assembly including an accumulator device coupled to the rotatable member, the accumulator device configured to store energy; an input device configured to be impinged by a fluid stream, the input device including an axis of rotation and a plurality of input members arranged about the axis of rotation; and a fluid input configured to receive the fluid stream and direct the fluid stream toward the input device; wherein energy from the fluid stream is stored in the accumulator device due to the impingement of the fluid stream on the input device, wherein the stored energy in the accumulator device is thereafter released to rotate the rotatable member to start the engine, wherein the plurality of input members are configured to be impinged by the fluid stream to cause the input device to rotate, and wherein each of the input members includes an arcuate surface configured to be impinged by the fluid stream.
