An exhaust system 37 for a compressor comprises an inlet for coupling to an exhaust port of the compressor, and preferably an exhaust muffler 41 for venting to atmosphere. An expansion volume 39, disposed between the inlet and the exhaust muffler, is provided for accommodating the expansion of gas exhausted from the compressor to suppress acoustic noise. The expansion volume may be a chamber which provides a stepped increase in cross-sectional area of the fluid flow path. A stepped decrease in cross-sectional area may be provided downstream of the increase in cross-sectional area. The muffler may comprise a sintered filter. The compressor may be part of a vehicle air suspension system. |
