Abstract
A compressor of a turbocharger is provided. The compression pipe of the compressor is connected to the intake pipe thereof by a return flow duct, in which an air recirculation valve is arranged for controlling the return flow of already compressed fresh air. The return flow duct opens into a groove of an intake manifold receptacle of the compressor, and at least one return flow opening adjoining the groove and facing an interior of the intake pipe is arranged on an intake manifold of the intake pipe.
Claims13
A compressor of a turbocharger, comprising:
- a compression pipe;
- an intake pipe;
- a return-flow duct connecting the compression pipe and the intake pipe, wherein a compression pipe end of the return flow duct is located in a compressor housing at a compressor wheel end of the compression pipe, and the return duct is configured to conduct return flow of already-compressed fresh air from the compression pipe to a location in the intake pipe upstream of an inlet end of the compressor wheel;
- and
- an overrun air recirculation valve arranged in the return-flow duct that controls the return flow of the already-compressed fresh air from the compression pipe to a location in the intake pipe, wherein
- the return-flow duct opens into a groove of an intake connector receptacle of the compressor, the intake connector receptacle being configured to receive an intake connector at a location in the intake pipe radially inward of the groove, and
- the groove is configured to pass the return flow radially inward through at least one return-flow opening in the intake connector to an interior space of the intake pipe upstream of the inlet end of the compressor wheel.

A turbocharger, comprising:
- a compressor having
- a compression pipe;
- an intake pipe;
- a return-flow duct connecting the compression pipe and the intake pipe, a compression pipe end of the return flow duct being located in a compressor housing at a compressor wheel end of the compression pipe, and the return duct is configured to conduct return flow of already-compressed fresh aft from the compression pipe to a location in the intake pipe upstream of an inlet end of the compressor wheel;
- and
- an overrun air recirculation valve arranged in the return-flow duct that controls return flow of the already-compressed fresh air from the compression pipe to a location in the intake pipe, wherein
- the return-flow duct opens into a groove of an intake connector receptacle of the compressor, the intake connector receptacle being configured to receive an intake connector at a location in the intake pipe radially inward of the groove, and
- the groove is configured to pass the return flow radially inward through at least one return-flow opening in the intake connector to an interior space of the intake pipe upstream of the inlet end of the compressor wheel.

A motor vehicle, comprising:
- a turbocharger having a compressor, the compressor having
- a compression pipe;
- an intake pipe;
- a return-How duct connecting the compression pipe and the intake pipe, wherein a compression pipe end of the return flow duct is located in a compressor housing at a compressor wheel end of the compression pipe, and the return duct is configured to conduct return flow of already-compressed fresh air from the compression pipe to a location in the intake pipe upstream of an inlet end of the compressor wheel;
- and
- an overrun air recirculation valve arranged in the return-flow duct that controls the return flow of the already-compressed fresh aft from the compression pipe to a location in the intake pipe, wherein
- the return-flow duct opens into a groove of an intake connector receptacle of the compressor, the intake connector receptacle being configured to receive an intake connector at a location in the intake pipe radially inward of the groove, and
- the groove is configured to pass the return flow radially inward through at least one return-flow opening in the intake connector to an interior space of the intake pipe at upstream of the inlet end of the compressor wheel.
