  • Thermal architecture of an air compressor
    Patent number: 11209004
    Abstract: Air compressor comprising a centrifugal-type compression wheel defining an axial direction and a radial direction, an air intake opening extending circumferentially around the compression wheel and opening onto a compression part, the compression part comprising a first portion forming a volute for the ejection of compressed air which is mounted facing the compression wheel in the radial direction, and an at least partly annular second portion extending around the first portion, the second portion comprising a central orifice receiving at least part of the compression wheel and an air deflection torus, the volute being made of metallic material and the torus made of thermoplastic material filled with non-metallic elements, the thermoplastic material having a thermal expansion corresponding to that of the metallic material.
