Abstract
The manifold cross-over control valve includes a powdered metal mounting base (10) which is mounted in a bore in a cross-over passage of an intake manifold (B). A frame (40) which extends into the cross-over passage from the mounting base seals against passage around its periphery and defines an exhaust gas aperture (42) therethrough. A pin (70) mechanically fastens the frame to the mounting base. A butterfly plate (80) is mounted on rotatable shaft (90) adjacent the frame for selectively opening and closing the exhaust gas aperture. The pin engages the butterfly plate in its fully open position to limit its rotational movement. A pneumatic actuator (D) is mounted by a bracket (30) to the mounting base for selectively rotating the shaft to control the passage of exhaust gases through the cross-over control valve.
