Abstract

835,713. Silencing gaseous currents. EHRHARDT, R. D. Feb. 22, 1957 [Sept. 26, 1956], No. 6127/57. Class 7(2) A silencer for a pneumatic tool has annular chambers 7...9 containing perforated tubes 12, 15 in a series-parallel arrangement. Air from the tool (not shown) is discharged into a central chamber 20 and enters the chamber 7 by openings 10, passing via logarithmically-spaced perforations 14 in the tubes 12 to the chamber 8 and thence via perforations 17 in the tubes 15 to the chamber 9 having discharge openings 11. The silencer has a tool-locating shoulder 18 and coupling sleeve 19.
