Title: SUPERCHARGER AND INTERNAL COMBUSTION ENGINE
Abstract:
Provided is a supercharger provided with: a first introduction part having a first flow channel for directing exhaust gas from a first exhaust introduction passage that leads to a turbine driven by the exhaust gas; a second introduction part having a second flow channel for directing exhaust gas from a second exhaust introduction passage that leads to the turbine; a chamber in which exhaust gas is introduced through the first flow channel and the second flow channel; an outlet part having one or a plurality of outlet flow channels for directing the exhaust gas within the chamber to the system exterior; and a valve member housed inside the chamber. The chamber has a first introduction port that leads to the first flow channel, a second introduction port that leads to the second flow channel, and one or a plurality of outlet ports that lead to the outlet flow channel. A main circulation space in which gas can circulate is secured on the main surface side of the valve member within the chamber. The valve member is able to rotate freely about axis, and the first introduction port, the second introduction port, and the outlet port are able to open and close in accordance with the rotational position around the axis line. The first introduction port, the second introduction port, and two or more opened ports among the outlet ports can be in communication through the main circulation space.
