ABSTRACT:
A silencer comprises a chamber with internal baffles mounted on a rod so that they can be manually reciprocated to scrape deposits off the chamber wall. A head at an end of the rod protruding from the chamber is screwable to a chamber end wall to hold the rod and baffles fixed during normal operation of the silencer. Loose material is expelled through a drain plug. The inlet and outlet are provided by a single through pipe which houses a tube separated into compartments by a partition. Gases enter the upstream compartment and flow through perforations in the tube and pipe into the chamber interior, then into an inverted trough through further perforations into the downstream compartment and the outlet. The chamber may be partly filled with water or a liquid cleanser, and may have cooling means.
