IMPELLER MODULE FOR A FUEL PUMP, CAPABLE OF IMPROVING DISCHARGE EFFICIENCY AND OF IMPROVING KINETIC ENERGY OF FUEL IN THE FUEL PUMP

摘要

PURPOSE: An impeller module for a fuel pump is provided to improve discharge efficiency by improving a blade shape of an impeller.;CONSTITUTION: An impeller module for a fuel pump comprises a lower case(4), an upper case(5), and an impeller(1). The lower case comprises a fuel inlet and a lower part fuel path(50). The upper case comprises a fuel outlet and an upper part fuel path(70). The impeller is inserted between the upper case and the lower case and rotates with power of a motor. Fuel flowing through the fuel inlet discharges through the fuel outlet with fuel kinetic energy generated by rotation of the impeller.;COPYRIGHT KIPO 2013
