ABSTRACT:
An evaporated fuel purge system has a fuel tank, an adsorption filter and a purge control valve. The evaporated fuel purge system is pressurized and depressurized through a venting flow path by a pump, so that the state of leakage therefrom is thereby inspected. For this inspection, a motor unit for driving the pump which applies or reduces pressure, an in-vehicle battery and a voltage control circuit which controls a battery voltage to a predetermined voltage and supplies the motor unit with a current are provided. The voltage control circuit is located in a pump chamber which forms a part of air outlet passage.
