Device for regulating the delivery pressure of a pump, for example, for feeding fuel to an internal combustion engine
The device includes a solenoid valve (32) having a supply conduit (34) communicating with the delivery of the pump (16), a drain conduit, an electromagnet (46) energizable to control an armature (51) controlling a shutter (44), and reducing means for reducing disturbance in the delivery pressure of...

| description | The device includes a solenoid valve (32) having a supply conduit (34) communicating with the delivery of the pump (16), a drain conduit, an electromagnet (46) energizable to control an armature (51) controlling a shutter (44), and reducing means for reducing disturbance in the delivery pressure of the pump (16) when the electromagnet (46) is energized. The reducing means include a chamber (64) having a predetermined volume and located between the supply conduit (34) and the drain conduit; and a fixed shield (91c) having an opening (92) in which slides a small-diameter portion (87) of the stem (52) of the armature (51). The electromagnet (46) is controlled by an electronic unit (31) via a modulator (86) for modulating the duty cycle of the control pulses, and via a circuit (103) for selecting the frequency of the control pulses on the basis of an estimate of hydraulic disturbances depending on at least one operating parameter. |
