摘要： To provide a waste-gate valve device with a good flow-rate controllability. A waste-gate valve device 1 includes: a turbine housing 3 provide with a waste-gate channel 2 through which exhaust gas bypasses a turbine; and a waste-gate valve 4 to open and close an outlet of the waste-gate channel 2. The waste-gate valve 4 includes a valve body 7 to open and close the outlet of the waste-gate channel 2, and a protrusion 8 to be housed in the waste-gate channel 2 when the valve body 7 closes the outlet of the waste-gate channel 2. The waste-gate channel 2 ensures a maximum flow rate of exhaust gas at a time when the waste-gate valve is fully open. An area ratio of a flow-path cross-sectional area A 1 of the waste-gate channel 2 to a flow-path cross-sectional area A 2 of a merging portion is not more than 0.2, the merging portion being a part at which exhaust gas having passed through the turbine merges. A widened portion 2A at which the flow-path cross-sectional area increases is disposed on the outlet of the waste-gate channel.

摘要： An exhaust turbo supercharger is provided that is able to effectively prevent exhaust gas that has flowed into between a turbine housing and a bearing housing from leaking to outside of the device, while allowing an excellent level of workability in assembly and disassembly. Included is a turbine housing, into which exhaust gas from an internal combustion engine is introduced; a turbine wheel which is provided within the turbine housing and which is rotation-driven by the exhaust gas; a turbine shaft, one end of which is inserted into the turbine housing, and to which the turbine wheel is attached; a bearing which supports the turbine shaft; and a bearing housing which is connected to the turbine housing and inside of which the bearing is housed. A bolt insert hole is formed in the turbine housing, and an internal thread insert made from a heat insulating material is provided in the bolt insert hole, and the turbine housing and the bearing housing are fixed by a bolt that engages with the internal thread insert.
