Abstract: A functional module includes: a mounting plate (2) for fluid tight attachment to the cylinder head of an internal combustion engine, incorporating portions (3) of air tract, and an injection set provided with support and attachment legs (6?) intended to rest directly on the cylinder head (7) notably at a first group of points of attachment (8) thereof. The mounting plate (2) is provided with primary attachment sites (9) intended to collaborate with a second group of points of attachment (8?) of the cylinder head (7), and with secondary attachment sites (9?) corresponding to at least some of the points of attachment (8) of the first group belonging to the cylinder head (7), the secondary attachment sites (9?) of the mounting plate (2) being intended to be positioned over the top of at least some of the legs (6?).

Abstract: A slide-valve device sliding in a predetermined axial direction, includes a valve body having two chambers, the first chamber including a lateral fluid-intake opening and a fluid-outlet opening provided with a normally closed, conditionally opening plug device, the second chamber including first and second lateral fluid-outlet openings, mutually offset in the axial direction. Two inner regions of the second chamber are arranged contiguously in the axial direction and communicate with one another via an opening or an internal passage, and in that the sliding drawer includes a first plug member suitable for selectively plugging the communication opening or the internal communication passage or opening between the two regions and a second plugging member suitable for preventing fluid communication between the second lateral fluid-outlet opening of the second chamber and a first region of the second chamber, within a predetermined range of translation of the sliding drawer.
