Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An 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 a second portion comprising an annular section extending around the first portion, the annular section extending radially inwardly and outwardly from the volute, the second portion further comprising a torus delimiting a central orifice receiving at least part of the compression wheel, the air compressor being characterized in that the volute is made of metallic material and the annular section of the second portion is made of thermoplastic material filled with non-metallic elements, and in that the thermoplastic material with non-metallic elements has a thermal expansion corresponding to that of the metallic material so as to allow mechanical clamping of the metallic material and the thermoplastic material with non-metallic elements. 2. The air compressor according to claim 1 , further comprising a first revolution casing extending between the air intake opening and the compression part, at least one air conveying channel allowing air to circulate in the axial direction from the air intake opening, and passages communicating with said at least one air conveying channel configured to allow air to circulate in the axial direction of the conveying channel towards the torus. 3. The air compressor according to claim 1 , wherein the volute is made of Aluminum. 4. The air compressor according to claim 1 , wherein the torus is made of carbon-filled polyetheretherketone. 5. The air compressor according to claim 1 , wherein the torus is an injection-molded part on the volute. 6. An aircraft comprising an air compressor according to claim 1 .
