Abstract
A boosted charge air system which eliminates adverse effects of pressure loading on the system components incorporates a pressure compensator mounted intermediate a turbocharger compressor section outlet duct and the inlet duct of a charge air cooler. The compensator includes first and second end bellows each with a first cross sectional area, a middle bellows intermediate the first and second end bellows with an annular cross sectional area substantially equal to the first cross sectional area, first and second end flanges connecting the first and second end bellows to the outlet duct and inlet duct, respectively, and first and second annular plates connecting the middle bellows to the first and second end bellows. An internal restraining structure for the compensator includes two sets of struts interconnecting the first end flange to the second annular plate and the second end flange to the first annular plate. For applications where exhaust pressure variations induce undesirable loading on the charge air system components a compensator, as described, is incorporated intermediate the exhaust manifold outlet duct and the turbine section inlet duct for the turbocharger.
