Claims

[Scope of utility model registration request]

a cylindrical casing body; a pump housing provided at one end of the casing body and having a fuel suction port and a fuel discharge port; a pump chamber serving as a fuel passage communicating with an outlet; and a turbine rotatably disposed within the pump chamber and configured to pump fuel sucked in from the suction port to the discharge port via the fuel passage of the pump chamber. , a vapor discharge hole bored in the pump housing to communicate the fuel passage of the pump chamber with the outside in order to discharge paper generated in the pump chamber to the outside; and a vapor discharge hole in the casing to drive the turbine to rotate. In the fuel pump including an electric motor provided in the main body, the pump housing is located on the outflow side of the vapor discharge hole, and is configured to laminarize the fuel discharged from the vapor discharge hole together with the vapor. A turbine-type fuel pump characterized by being provided with a rectifying member.
