Abstract

Keksinnön kohteena on turboahdin, joka käsittää kompressorikotelon (10), kompressorikotelon sisällä olevan kompressoripyörän (12), ensimmäisen turbiinikotelon (14), ensimmäisen turbiinikotelon sisällä olevan ensimmäisen turbiinipyörän (16), jolla on säde r1, toisen turbiinikotelon (18), toisen turbiinikotelon sisällä olevan toisen turbiinipyörän (20), jolla on säde (r2) ja akselin (22), jolle kompressoripyörä, ensimmäinen turbiinipyörä ja toinen turbiinipyörä on järjestetty. Ensimmäinen turbiinipyörä ja toinen turbiinipyörä ovat olennaisesti erikokoisia.The invention relates to a turbocharger comprising a compressor housing (10), a compressor wheel (12) inside a compressor housing, a first turbine housing (14), a first turbine wheel (16) having a radius r1 inside a first turbine housing, a second turbine housing (18), a second turbine housing a second turbine wheel (20) having a radius (r2) and a shaft (22) on which the compressor wheel, the first turbine wheel and the second turbine wheel are arranged. The first turbine wheel and the second turbine wheel are substantially different sizes.
