Abstract: 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.

Abstract: A compressor recirculation valve having a noise-suppressing muffler. The muffler has a double-walled construction, including a perforated outer wall and a non-perforated inner wall. The muffler is arranged surrounding the RCV such that when the RCV valve member is in an open position, compressed recirculation air is constrained to flow along the non-perforated inner wall and past an upper end thereof before reaching and flowing radially outwardly through the perforated outer wall to a transverse flow passage for delivery back into an inlet of the compressor.

Abstract: The invention relates to information security technologies, provides a content security transmission device and a content security transmission system which separate data transmission function of a digital interface from data management and processing function thereof, and provides a content security transmission method based on the device and the system. The content security transmission protection device comprises digital interfaces and a management/processing unit, the management/processing unit is configured in a specific chip in the device, used for updating a revocation list stored therein and collecting information from downstream devices. A transmitting device and a forwarding device in the content security transmission protection system comprise digital interfaces and management/processing units.
