eCBV module
An electronic compressor bypass valve (eCBV) module includes a pedestal housing, and a compressor bypass valve mounted to the pedestal housing. An inlet port, a first outlet port, and a second outlet port are integrally formed as part of the pedestal housing, where pressurized air flows into the inlet port. The eCBV module also includes a venturi device at least partially disposed in the second outlet port. When the compressor bypass valve is in an open position, a portion of the pressurized air flows through the first outlet port, and a portion of the pressurized air flows from the inlet port through the venturi device and through the second outlet port. When the compressor bypass valve is in the closed position the pressurized air is prevented from flowing into the first outlet port, and all of the pressurized air flows through the venturi device and through the second outlet port.
