Abstract

1412403 Silencers QUIETFLO ENG Ltd 24 Nov 1972 [10 Sept 1971] 42329/71 Heading F1B An air inlet silencer has a housing with an inlet 15 Fig. 1, and an outlet 28 connected to a compressor inlet and a choke tube 30...17 extending from the inlet and opening within the housing, and following an overall path which is non-rectilinear. Part of the housing may be lined with sound absorbent material 27. In another embodiment an air filter 40, Fig. 2 may be arranged before the inlet.
