Abstract
The present invention provides a regenerative pump for supplying fuel into an injection device for an internal combustion engine. The regenerative pump has a longer pressurizing passage and a slanted discharge port connected thereto and formed at an outer periphery thereof. The pressure loss in the pump is small because the fuel flows smoothly into the discharge port from the pressurizing passage, and accordingly the efficiency of the pump is high and the pump can be made small in size at the same time.
