Patent ID: 8511262

Claim:
A sliding-drawer slide valve device operating in a given axial direction, comprising: a sliding drawer, and a valve body with first and second chambers that communicate with one another and are contiguous in an axial direction of the device, the first chamber comprising a first lateral fluid-intake opening and a second fluid-outlet opening located essentially opposite a communication opening ( 6 ) with the second chamber, the first chamber equipped with a blocking device that closes and opens conditionally, the second chamber comprising first and second lateral fluid-outlet openings that are mutually offset in the axial direction, and that emerge respectively into first and second regions or inside volumetric zones that are separate from said second chamber, the sliding drawer being guided in translation in said second chamber and movable under the action of a monitored-control actuator, the first and second inside regions ( 9 and 9 ′) of said second chamber ( 4 ′) arranged in a contiguous manner in the axial direction (X) and communicate with one another by an opening or inside communication passage ( 11 ), the sliding drawer ( 2 ) comprising: a first blocking element ( 12 ) that can selectively block, in two opposite end sliding positions of the sliding drawer ( 2 ) and by compression of a respective corresponding joint ( 14 , 14 ′), the communication opening ( 6 ) between the first and second chambers ( 4 and 4 ′) or the opening or inside communication passage ( 11 ) between the first and second inside regions ( 9 and 9 ′) of the second chamber ( 4 ′), and a second blocking element ( 12 ′) that can prevent fluid communication between the second lateral fluid-outlet opening ( 8 ′) of the second chamber ( 4 ′) and the first inside region ( 9 ) of said second chamber ( 4 ′), in a defined range of translational movement of the sliding drawer ( 2 ) from its end position for blocking the communication opening ( 6 ) between the two first and second chambers ( 4 and 4 ′).
