ABSTRACT:
A fuel supply apparatus includes a flow control valve, a housing, a movable portion, a compression coil spring and a coil constructed integrally with a fuel pump (or separately from the fuel pump). The movable portion may be made of magnetic material and attracted to the fuel downstream side against the spring force of the compression coil spring by an electromagnetic attracting force generated by an electric current supplied to the coil. A fuel drain opening can be created by aligning a first communication passage to release an excess part of the fuel passing through fuel passages back to the fuel tank through the drain passage in accordance with an engine operation condition.
