摘要： 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.

摘要： A fuel pump includes a case member defining a fuel passage and a discharge-side cover connected to the case member and defining an outlet port. A pump section has an inlet port and is connected to the case member. A motor section is housed in the case member for driving the pump section. A positive electrode terminal and a negative electrode terminal are supported by an insulative terminal support member fixed to the discharge-side cover. Base portions of the positive and negative electrode terminals are covered by insulative portions. The insulative portions are fitted in fitting holes of the discharge-side cover. The discharge-side cover has guide portions on its inner surface. The terminal support member has engagement projections on opposite side walls thereof. The engagement projections are guided by the guide portions to restrict the discharge-side cover from rotating with respect to the terminal support member.
