CENTRIFUGAL COMPRESSOR HOUSING

Abstract

A housing for a radial flow compressor, particularly for a turbocharger, comprises a first housing part and a second housing part joined together to form at least part of the housing, each of the housing parts comprising at least one cavity, said cavities in fluid communication, when the housing parts are juxtaposed, forming a cavity system into which a fluid jointing compound, such as an adhesive, thermoplastic material, etc., is introduced to form a solid joint of said both housing parts, wherein the housing parts are dimensioned such that a gap for introducing the fluid jointing compound extends from a free housing surface of the housing parts when juxtaposed, along facing jointing surface sections of the housing parts, and ports into the cavity system.

Description

DESCRIPTION OF THE DRAWINGS

Claims

1. A housing for a radial flow compressor comprising a first housing part and a second housing part joined together to form at least part of the housing, each of the first and second housing parts comprising at least one cavity, said cavities in fluid communication, when the housing parts are juxtaposed, forming a cavity system into which a fluid jointing compound is introduced to form a solid joint of said both housing parts, wherein the housing parts are dimensioned such that a gap for introducing the fluid jointing compound extends from a free housing surface of the housing parts when juxtaposed, along facing jointing surface sections of the housing parts, and ports into the cavity system.

2. The housing as set forth in claim 1, wherein the first housing part and second housing part define a compressor channel of the radial flow compressor.

3. The housing as set forth in claim 2, wherein the first housing part forms a radial outer portion of the compressor channel and the second housing part forms a radial inner portion of the compressor channel for insertion into the outer portion.

4. The housing as set forth in claim 2, wherein the first housing part forms an inlet of an air intake port, and the second housing part forms a transition of the air intake port porting into the compressor channel.

5. The housing as set forth in claim 4, wherein the gap surrounds the axis of the air intake port.

6. The housing as set forth in claim 5, wherein the gap concentrically surrounds the axis of the air intake port.

7. The housing as set forth in claim 1, wherein the gap extends radially from the free surface in the housing and translates into an axial section porting into the cavity system which is oriented radially.

8. The housing as set forth in claim 4, wherein the gap extends from a free surface of the air intake port.

9. The housing as set forth in claim 1, wherein the jointing surfaces of the housing parts, except the jointing surface sections forming the gap, each form a flange surface section, said flange surface sections being juxtaposed when the housing parts are juxtaposed.

10. The housing as set forth in claim 9, wherein the flange surface sections extend radially.

11. The housing as set forth in claim 9, wherein the jointing surface sections forming the gap and the flange surface sections interface via an axial jointing surface portion at which the cavity system is configured.

12. The housing as set forth in claim 1, wherein a seal is arranged in the region of the jointing surface on a side of the cavity system facing away from the gap.

13. The housing as set forth in claim 12, wherein the seal is arranged in the region of an axial jointing surface portion.

14. The housing as set forth in claim 12, wherein for the seal a recess is provided formed at least by one of the housing parts.

15. The housing as set forth in claim 14, wherein the seal is an O-ring is inserted into the recess.

16. The housing as set forth in claim 12, wherein the seal is designed to hamper passage of the fluid jointing compound but permit blow-by of air.

17. The housing as set forth in claim 1, wherein the radial flow compressor is a turbocharger.

18. A centrifugal compressor having a housing comprising a first housing part and a second housing part that, when joined together, form at least part of the housing, wherein each of the first and second housing parts includes a cavity that when the housing parts are juxtaposed, said cavities are in fluid communication and form a cavity system into which a fluid jointing compound can be introduced to form a solid joint of said both housing parts, wherein the housing parts are dimensioned such that a gap for introducing the fluid jointing compound extends from a free housing surface of the housing parts when juxtaposed, along facing jointing surface sections of the housing parts, and ports into the cavity system.

19. The centrifugal compressor as set forth in claim 18, wherein the centrifugal compressor is a turbocharger.

20. The centrifugal compressor as set forth in claim 18, wherein the jointing surfaces of the housing parts, except the jointing surface sections forming the gap, each form a flange surface section, said flange surface sections being juxtaposed when the housing parts are juxtaposed, and wherein the jointing surface sections forming the gap and the flange surface sections interface via an axial jointing surface portion at which the cavity system is configured.
