  • Patent number: 4729722
    Abstract: A turbo compressor mounted upon a hollow box-like housing is provided with a noise suppressor which includes a rectangular open ended box-like structure suspended from the housing by flexible walled tubes which constitute an air inlet and an air outlet to the housing through which air flows to prevent heat build up within the housing. The suppressor walls are lined with a sound absorbent material which, combined with the non-rigid suspension of the suppressor from the housing and the non-linear air entrance and exit paths to and from the housing, suppresses sound generated by flow of high pressure air from the compressor into the housing through a shaft bearing. Noise generated by the flow of air into the compressor inlet is reduced by blocking the inlet with a block of porous foamed plastic material which also functions as an inlet filter.
