gases from the engine exhaust manifold 16 the exhaust gas outlet passage 34 directs a metered flow of the exhaust gases toward an engine inlet manifold not shown flows between the exhaust gas inlet passages 30 and 32 and the combined exhaust gas outlet passage 34 are interrupted by a dual poppet head body 36 that is movable along a central axis 38 the dual poppet head body 36 includes a a first poppet head 40 that mates with a seat 42 encircling an end of the inlet passage 30 for restricting flows between the inlet passage 30 and the combined outlet passage 34 and b a second poppet head 44 that mates with a seat 46 encircling an end of the inlet passage 32 for restricting flows between the inlet passage 32 and the combined outlet passage 34 the two poppet head seats 42 and 46 have equally sized pressure areas and the inlet passages 30 and 32 apply exhaust gas pressure to the two poppet heads 40 and 44 from opposite directions to balance the dual poppet head body 36 with respect to the exhaust gas pressure the dual poppet head body 36 also includes a shank 48 mounted within a guide bore 50 of a housing flange 52 the shank 48 communicates motion along the central axis 38.
