Abstract: A fuel pump includes a mechanical regulating valve arranged in a pump body which modulates the pressure in a high pressure space so that the pressure matches the engine demand. Modulation by the regulating valve requires adjustment of the inlet fuel quantity, adjustment of the volume of the high pressure space, and control of a return fluid communication enabling fuel to exit the high pressure reservoir.

Abstract: In a fan module (10) of a vehicle engine, the fixed shroud (12) of the module (10) has a circular opening (16) receiving a fan (14) rotating about a main axis (X). The opening (16) is circumvented by a peripheral wall (18) cylindrically extending in the downstream direction (DD) beyond the fan (14) toward a corner edge where the wall (18) angles radially and inwardly to extend toward a circular downstream edge. The downstream portion of the peripheral wall (18) forms an annular channel (C) opening in the upstream direction (UD) The channel (C) forming an axial continuation of the gap (G) that is between the tips (22) of the blades (20) of the fan (14). The gap (G) is continuous, non-divided and non-partitioned.
