摘要

#CMT# #/CMT# The device has a sound absorption element and a circulating wall, from which a section of a metal fabric is made of pores or a micro-perforated sheet metal. The pores with a chaining thread and a filling thread are formed between the chaining thread and filling thread. A wall is provided, which is made of a sound-impermeable material. #CMT#USE : #/CMT# Device for sound absorption in an air head pump provided with a supply line and an exhaust air duct (Claimed). #CMT#ADVANTAGE : #/CMT# The device has a sound absorption element, and a circulating wall, from which a section of a metal fabric is made of pores or a micro-perforated sheet metal, and hence ensures simple and economical absorption of sound. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of an air head pump with a sound absorbing device. 1 : Air head pump 2 : Outer wall 3 : Heating pump 4 : Supply line 5 : Exhaust air duct.
