Patent ID: 6898934

Claim:
A method for providing an external blow-off valve for a turbocharger compressor having a recirculation valve configured for attachment to a valve mounting flange defining a recirculation valve inlet port and a recirculation valve outlet port that are selectively connected to one another by the recirculation valve when the recirculation valve is operating in a recirculation mode, to thereby provide internal recirculation from a compressor outlet operatively connected in fluid communication with the recirculation valve inlet port to a compressor inlet operatively connected in fluid communication with the recirculation valve inlet port, and disconnected from one another by the recirculation valve when recirculation valve is not operating in the recirculation mode, to thereby block internal recirculation between the compressor outlet port and the compressor inlet port, the method comprising installing an external blow off adaptor between recirculation valve and the valve mounting flange.
