Abstract
A turbocharger () has an improved wastegate valve assembly () wherein a port-controlling valve body () includes flow formations which serve to reduce exhaust gas flow in non-optimal directions transverse to an optimal flow direction in the direction of a wastegate passage (). These flow formations serve to optimize or maximize the flow of exhaust gas in the optimal or primary flow direction as the exhaust gas flow turns through a turn angle () from an inlet direction () to the optimal flow direction.
