摘要: A piston pump for feeding a liquid in a vehicle having at least one piston, which is configured to cyclically slide inside a housing between a top dead centre and a bottom dead centre. The liquid is usually fed along a main feeding direction from a suction duct to a delivery duct. The piston pump has two solenoid valves, which are each arranged in the suction duct and in the delivery duct, respectively, and are designed to be operated by an electronic control unit so as to reverse the liquid feeding direction from the main feeding direction to a secondary feeding direction opposite the main liquid feeding direction and/or so as to adjust the cylinder capacity of the piston pump. The piston is operated by an electromechanical actuator, in particular comprising an electromagnet.

摘要: 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.
