Abstract
A fluid apparatus, which is provided for supplying fluid into an internal combustion engine, includes an upstream pump, which is electrically driven, having an outlet port. The fluid apparatus further includes a downstream pump, which is electrically driven, having an inlet port that is connected with the outlet port in series. The fluid apparatus further includes an open-close unit. The open-close unit communicates a fluid passage through which the upstream pump supplies fluid to the internal combustion engine when the downstream pomp stops. The open-close unit blocks the fluid passage when the downstream pomp operates.
