Abstract:
An assembly comprising: an internal combustion engine intake manifold and an exhaust gas recirculation (EGR) valve recirculating engine exhaust gases into the manifold, the manifold comprising a wall separating an internal manifold space from an external space, the wall comprising opposite wall portions each containing a respective through-hole, the EGR valve comprising a body having an inlet port receiving engine exhaust gases, an outlet port delivering engine exhaust gases to the internal manifold space, a valve mechanism controlling flow of engine exhaust gases from the inlet port to the outlet port, a first mount mounting the valve body on the manifold wall in closure of a first one of the manifold wall through-holes and disposing the outlet port in the internal manifold space, and a second mount comprising a surrounding wall in closure of a second one of the manifold wall through-holes and an inlet tube that contains the inlet port, the surrounding wall comprises an axial wall portion extending from the second of the manifold wall through-holes and a radial wall portion extending radially inward from the axial wall portion to the inlet tube, the surrounding wall and at least a portion of the inlet tube are respective integral formations of a single part, and the surrounding wall defining with the inlet tube an annular space surrounding the inlet tube and opening to the external space.
