Abstract
A compressor for a turbocharger may include a compressor wheel with compressor blades mounted in a housing defining a compressor inlet. The compressor inlet may include an inner pipe and an outer pipe surrounding said inner pipe. The inner pipe may be directed toward the radially inner region of the compressor blades and the outer pipe directed toward the radially outer region of the compressor blades. The passage cross section of the outer pipe and/or of the inner pipe may be at least partially shut off by means of shutoff devices.
Claims14
A compressor of a turbocharger, the compressor comprising:
- a compressor housing,
- a compressor wheel mounted therein, with compressor blades and a compressor inlet,
- wherein the compressor inlet comprises, at least in a section adjacent to the compressor housing, an inner pipe and an outer pipe surrounding said inner pipe,
- the inner pipe is directed toward the radially inner region of the compressor blades and the passage cross section of the outer pipe and/or of the inner pipe operable to be at least partially shut off by means of shutoff devices,
- wherein the outer pipe is directed toward the radially outer region of the compressor blades,
- the compressor inlet comprises two pipes arranged adjacent to one another, of which one is passed into the interior of the other and extends as far as the compressor housing as an inner pipe extending in the outer pipe, and in that the shutoff devices are arranged in at least one of the pipes arranged adjacent to one another.
An internal combustion engine comprising:
- a compressor housing,
- a compressor wheel mounted in the compressor housing, the compressor wheel having compressor blades,
- a compressor inlet including, at least in a section adjacent to the compressor housing, an inner pipe and an outer pipe surrounding said inner pipe,
- the inner pipe directed toward the radially inner region of the compressor blades and the outer pipe directed toward the radially outer region of the compressor blades,
- a set of shutoff devices arranged in at least one of the pipes and operable to at least partially shut off the passage cross section of the outer pipe and/or of the inner pipe.
