Abstract
A restraint system (300, 300′, 500) for a vaned diffuser (225) of a turbocharger (100) or other fluid boosting device is provided that can reduce or eliminate losses. The system (300, 300′, 500) uses a structure to provide both a pressure load on the vaned diffuser (225) and a seal for the vaned diffuser (225). The structure can be a fluoroelastomer O-ring (350, 350′, 550). The O-ring (350, 350′, 550) can be positioned at least partially in a channel (325, 325′, 525) formed in at least one of the diffuser ring (206, 206′), the compressor housing (103) and the center housing (102).
