Beschreibung
Zusammenfassung:	A turbocharger (10) that uses exhaust gas flow to drive a turbine wheel (12) having a barrel or piston-type wastegate valve assembly (26, 126) with a wastegate valve (28, 128) that controls exhaust gas flow bypassing the turbine wheel (12) to control turbine work. A cylinder (30, 130), which may have a through hole (32, 132), is moveable in a tubular chamber (22) and functionally operates with a wastegate port (24) in the turbine housing (20) for controlling exhaust gas flow. An actuator (36, 136) operably controls movement of the cylinder (30, 130).
