Abstract: A piston-type fuel pump has two or more cylinder bores in a barrel. A piston in each cylinder bore has a port for admitting fuel into the cylinder bore. A swash plate assembly includes a wobble plate connected to each of the pistons. The wobble plate is given an oscillatory motion producing reciprocal movement of the pistons. A thin-walled metal bellows defines a closed interior space surrounding the pistons to prevent escape of fuel.

Abstract: An electromagnetic pump is disclosed in which a pair of check valves and a pressure-regulating mechanism are inserted in series in a fluid passage extending from a suction inlet to a discharge outlet and a pressure chamber operatively connected with a plunger is provided between the check valves. When a solenoid coil surrounding the plunger is supplied with an intermittent electric current, the plunger moves to and fro, thereby the pressure in the pressure chamber being varied to have the check valves given rise to pumping action. The pressure-regulating mechanism function to control the pressure of fluid discharged from the outlet, thereby absorbing the pulsation generated by the reciprocal pumping action of the plunger.

Abstract: A method is described to control an actuation profile of an electromechanical linear actuator device of an internal combustion engine designed to control the movement of a component; the internal combustion engine comprises a sensor, which faces the actuator device and is designed to detect the noise generated by the movement of the component; the method comprises the steps of acquiring, by means of the sensor, the intensity of a signal generated by the impact of the component against a limit stop; identifying a first listening window of the signal associated with said impact; calculating a noise index inside the listening window; comparing the noise index with a reference value; and controlling the actuation profile of the actuator device based on this comparison.

Abstract: A plug-in pump for a common-rail system has a pump housing having a cylinder formed therein and a piston guided in the cylinder, a fuel inlet, and a fuel outlet. The pump housing also includes a plug-in section for inserting the pump housing into an opening of an engine component, and a flange that delimits the plug-in section, for fastening the pump housing to the engine component. To cool the plug-in pump, the pump housing has at least one flow duct with a separate fluid inlet and a separate fluid outlet. The fluid inlet is connectable to a fluid-discharging line of the internal combustion engine, and the fluid outlet is connectable to a fluid-receiving line of the internal combustion engine.
