ABSTRACT:
An engine-exhaust gas driven turbo compressor has a controllable diaphragm valve (13, 15) in a flow path (20, 24) between a compressor delivery port (6) and an atmospheric inlet port (4), this valve being controllable to regulate gas flow via the compressor wheel member (2) to avoid compressor surging when the demand is low and a compressed torroidal wire mesh element (23) is accomodated in an annular region (22) of the compressor housing between the valve (13, 15) and the inlet port to suppress noise resultant upon operation of the valve.
