TURBOCHARGER WITH VANED DIFFUSER FOR THE COMPRESSOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240044263 titled 'TURBOCHARGER WITH VANED DIFFUSER FOR THE COMPRESSOR

Simplified Explanation

The abstract describes a turbocharger with a centrifugal compressor that includes a vaned diffuser. The diffuser ring, which is separate from the compressor housing and center housing, is installed between them to create a diffuser passage. The diffuser ring has integral vanes that only partially extend across the axial width of the diffuser passage. A rectangular-section seal ring is compressed between the compressor housing and the diffuser ring for sealing and axial locating of the diffuser ring. The diffuser ring is radially located by an integral locating pin on the ring, which fits into a receptacle in the center housing.

  • The patent describes a turbocharger with a centrifugal compressor and a vaned diffuser.
  • The diffuser ring is separate from the compressor housing and center housing.
  • The diffuser ring is installed between the compressor and center housings to create a diffuser passage.
  • The integral vanes on the diffuser ring only partially extend across the axial width of the diffuser passage.
  • A rectangular-section seal ring is compressed between the compressor housing and the diffuser ring for sealing and axial locating.
  • The diffuser ring is radially located by an integral locating pin on the ring, which fits into a receptacle in the center housing.

Potential Applications:

  • Automotive industry - Turbochargers are commonly used in automotive engines to increase power and efficiency. This innovation could improve the performance of turbochargers in vehicles.
  • Aerospace industry - Turbochargers are also used in aircraft engines. This technology could be applied to enhance the efficiency and power output of turbochargers in aircraft engines.

Problems Solved:

  • Enhanced radial locating of the diffuser ring, providing stability and proper alignment within the turbocharger.

Benefits:

  • Increased performance and efficiency of turbochargers.
  • Improved airflow and reduced leakage.
  • Enhanced stability and alignment of the diffuser ring within the turbocharger.


Original Abstract Submitted

a turbocharger having a centrifugal compressor includes a vaned diffuser. the vaned diffuser is formed by a diffuser ring formed separately from the compressor housing and center housing. the diffuser ring is installed between the compressor and center housings such that a diffuser passage is defined between a surface of the compressor housing and a surface of the diffuser ring. integral vanes on the diffuser ring extend only partially across the axial width of the diffuser passage. a rectangular-section seal ring is axially compressed between the compressor housing and the diffuser ring for sealing and axial locating of the diffuser ring. radial locating of the diffuser ring is accomplished by an integral locating pin on the ring, which fits into a receptacle in the center housing.
