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.
