The invention relates to an exhaust gas turbocharger (1) including a turbine housing (2). A turbine is arranged in the turbine housing. The turbine housing (2) includes two exhaust gas channels (3, 4)separated by a partition (5) from one another. A wastegate valve (6) may be arranged such that the at least two exhaust gas channels (3, 4) are connectable to a bypass duct (7) bypassing the turbine.The wastegate valve (6) includes a valve body (8) and a valve seat (9) interacting with the valve body (8). The wastegate valve may be configured such that a ram supercharging operation and a pulse supercharging operation is activated depending on a degree of opening of the wastegate valve (6). 本发明涉及一种带有涡轮机壳体(2)的排气涡轮增压器(1)，涡轮机设置在涡轮机壳体中，其中：-涡轮机壳体(2)具有两个排气通道(3，4)，其通过隔板(5)相互分隔；-提供了废气门阀(6)，通过该废气门阀，两个排气通道(3，4)能与旁通管(7)连通，该旁通管绕过涡轮机。本发明的本质在于，废气门阀(6)具有单个阀体(8)和与之相互作用的阀座(9)，并以下述方式设计，滑块增压或脉冲增压的发生基于废气门阀(6)的打开的程度。
