摘要： The present invention concerns a valve assembly for low- pressure applications of the controlled recirculation of the exhaust gases of an internal combustion engine (MCI), the body whereof (1) comprises a flow conduit (Ia) with at least one entry section and one exit section, as well as at least one moving element (5) with valve function, cooperating with a valve seat (6) and consisting of the coupling of one bearing element and of one sealing element. The valve body comprises a main conduit (Ia), with a first outflow section (2) and a second outflow section (3) at the two ends, and a secondary conduit (1b), which has a third outflow section (4), at one of the ends thereof, and which, at the other end, connects to said main conduit through an interface section (9a). Said moving element (5) is a sealing element of the valve seat and, at the same time, a partialisation means of the flow rate of the flows in said main and secondary conduits; for this reason it is capable of moving, in its path between the closing position on said valve seat (6) and its fully-open position, on a first portion exclusively within the secondary conduit (1b), namely between the closing position on said valve seat (6) and said interface section (9), and subsequently, on a second portion, through the port of said primary conduit (Ia). Said moving element is in the form of a vane and disc, where the vane-shaped element takes on the flow-adjusting function and the disc- shaped element takes on the valve seat sealing function. The invention furthermore concerns a recirculation system of the exhaust gases in an internal combustion engine, wherein said valve assembly can be inserted on the (MCI) engine, intake side or discharge side.
