Abstract
A piston-type fuel pump is provided. The fuel pump includes a housing bounding an internal cavity with a cylindrical tube disposed in the internal cavity. The cylindrical tube provides a bore extending along an axis and a piston is disposed in the bore. A spring is configured to bias the piston in a first direction along the axis. A coil is disposed about the cylindrical tube and a control circuit is disposed in the internal cavity. The control circuit is configured in electrical communication with the coil. The voltage supplied to the control circuit can be varied, with the control circuit compensating for the variable supply voltage to regulate the actuation of the coil from a de-energized state to an energized state. The piston is biased in a second direction opposite the first direction in response to the coil being actuated.
