Claims

[Claims for Utility Model Registration] 1. A turbo supercharger having a scroll portion that surrounds a turbine wheel and defines a turbine chamber so as to rotate the turbine wheel by exhaust gas exhausted from an internal combustion engine. An exhaust gas passage chamber having an exhaust gas jet port facing the peripheral edge of the turbine impeller is formed in the scroll portion along the circumferential direction thereof, and a partition wall movable in the turbine axle direction is provided, and the partition wall is provided with a partition wall movable in the turbine axle direction. A turbo supercharger characterized in that a partition wall control means is provided for variably expanding and contracting a cross-sectional area within the exhaust gas passage chamber. 2. The partition wall is located within the scroll portion and faces the peripheral edge of the turbine wheel along the circumferential direction thereof to form an exhaust gas passage chamber divided into two, and the cross-sectional area of each exhaust gas passage chamber is variable. The turbo supercharger according to claim 1 of the above-mentioned utility model registration, which is configured to expand and contract. 3. The turbo turbocharger according to claims 1 and 2, wherein the partition wall is formed by overlapping partition plates, and has a reciprocating means for expanding and contracting the cross-sectional area within the exhaust gas passage chamber. feeding machine. 4. The above-mentioned utility model registration claim, wherein the partition wall control means is configured to reduce the cross-sectional area of the exhaust gas passage chamber formed in the scroll part when the internal combustion engine rotates at a low speed below a set rotation speed. Turbo supercharger listed in scope 1.
