Abstract: A compressor assembly includes a compressor housing and a positive crankcase ventilation (PCV) tube. The compressor housing has an inlet port configured to receive intake air at ambient pressure, an outlet port configured to discharge pressurized air, and a hollow cylindrical section having an inner radial surface and an outer radial surface. The inner radial surface of the hollow cylindrical section defines the inlet port of the compressor housing. The PCV tube is configured to allow airflow between a crankcase of an engine and the inlet port of the compressor housing. The PCV tube extends through the hollow cylindrical section of the compressor housing and beyond the inner radial surface of the hollow cylindrical section.
