Abstract:
A wastegate assembly with a valve head moved linearly toward and away from a wastegate port via a valve stem. When the valve is in an open position the valve seat face of the valve head is spaced apart from the valve seat. When the valve is in a closed position the valve seat face of the valve head is secured against the valve seat. The wastegate assembly includes a sidewall surrounding the wastegate port elongated in the direction of valve movement. The contoured side wall widens going away from the valve seat. The minimum flow area through the wastegate port is controlled such that the flow is choked via the side wall rather than the valve curtain area. The contoured side wall can be recessed into the housing or extend from the housing.

Claim (Index 1):
An exhaust gas turbocharger including:\n a turbine housing ( 210 ) including a turbine volute adapted to guide exhaust gas flow to a turbine wheel housed in the turbine housing ( 210 ); a bypass channel formed in the turbine housing; a wastegate port ( 214 ) communicating between the turbine volute upstream of the turbine wheel and the bypass channel; a valve seat ( 226 ) immediately around the wastegate port ( 214 ); a linear valve ( 216 ) having a valve stem ( 220 ) connected to a valve head ( 222 ), the valve head ( 222 ) dimensioned to seat on said valve seat ( 226 ), the linear valve ( 216 ) operable to move the valve head ( 222 ) between a seated position and an open position relative to the wastegate port ( 214 ) for selectively blocking and unblocking the wastegate port ( 214 ); and a side wall ( 230 ) including an extending wall portion formed by the bypass channel of the turbine housing ( 210 ) so as to surround the valve head ( 222 ) as the valve head ( 222 ) moves between the seated position and the open position;\n wherein the extending wall portion of the sidewall ( 230 ) forms a throat area (At) between the extending wall portion and valve head ( 222 ), the throat area (At) gradually increasing as the valve head ( 222 ) moves from the seated to the open position; and \n wherein flow of exhaust gas through the bypass channel is controlled by the a throat area (At) between the extending wall portion of the sidewall ( 230 ) and valve head ( 222 ).
