Problems solved by technology
However, due to the interface between the multiple parts, the volute has leakage and tightness issues, resulting in loss of airflow and inefficiency
[0019] Furthermore, it is currently not possible to use die casting to form a one-piece volute with a cross-sectional shape provided with this lip, as the lip would prevent the metal core from being removed from the volute after the casting process is complete

Embodiment Construction
[0107] Referring to FIGS. 1-3 , there is shown a known variable geometry turbocharger comprising a turbine 41 and a compressor 40 interconnected by a bearing assembly 60 .
[0108] The turbine 41 comprises a turbine 5 mounted on one end of the shaft 4 for rotation within the turbine housing 1 . The compressor 40 includes an impeller 6 mounted on the other end of the shaft 4 for rotation within the compressor housing 2 . The compressor housing 2 has a central longitudinal axis 4a.
[0109] The turbine housing 1 and the compressor housing 2 are interconnected by a central bearing housing 3 . The turbocharger shaft 4 extends from the turbine housing 1 through the bearing housing 3 to the compressor housing 2 . The shaft 4 rotates on bearings located in the bearing housing 3 about an axis substantially parallel to and coincident with the longitudinal axis 4 a of the compressor housing 2 .
[0110] Between the compressor housing 2 and the bearing housing 3 is a diffuser plate 2a...

A method of manufacturing a compressor housing comprising arranging a core with a die so as to define a mould cavity, providing a molten metal within the mould cavity and solidifying the molten metal to form a compressor housing comprising a diffuser first wall member and an outlet volute first wall member; the compressor housing being formed such that for at least one circumferential position about the compressor housing longitudinal axis, a first angle is subtended between an outlet section of a surface of a diffuser first wall member and a first section of a surface of an outlet volute first wall member, the outlet volute first wall member being formed with an opening, wherein after the compressor housing has been formed in the mould cavity, the core is removed from the volute passage, once the core has been removed from the volute passage, a cut is applied, through the opening, to the first section of the surface of the outlet volute first wall member, at the least one circumferential position, to produce a cut section such that a second angle is subtended between the cut section and the outlet section of the surface of the diffuser first wall member, at said at least one circumferential position, that is greater than the first angle.
Description
technical field [0001] The present invention relates to a method of manufacturing a compressor housing for accommodating an impeller to provide a compressor, and in particular, but not exclusively, to a method of manufacturing a compressor housing for use in a turbocharger, such as a variable geometry turbocharger. way of the compressor housing. The invention also relates to a method of manufacturing a compressor, and in particular but not exclusively to a method of manufacturing a compressor for use in a turbocharger, such as a variable geometry turbocharger. Background technique [0002] The compressor includes an impeller having a plurality of blades (or vanes) mounted on a shaft for rotation within the compressor housing. In a centrifugal compressor, rotation of the impeller causes gas (eg, air) to be drawn into the impeller and delivered to an outlet volute defined at least in part by a compressor casing surrounding the impeller. [0003] One use of compressors is in ...
