Title:
SILENCER
Document Type and Number:
WIPO Patent Application WO/2006/075670
Kind Code:
A1
Abstract:
A silencer, wherein a cylindrical member (20) is held between a body (16) connected to the exhaust side of a fluid pressure device (12) and a disk-like holding part (18) and a net-like sound absorbing part (22) is disposed so as to surround the outer periphery of the cylindrical member (20). A pressure fluid flows from the body (16) to the inside of the cylindrical member (20), and is discharged to the sound absorbing part (22) side through a plurality of first to fifth exhaust holes (70a to 70e) formed in the cylindrical member (20). Thus, after dirt in the pressure fluid is removed and exhaust noise is absorbed by the sound absorbing part (22) formed by laminating a plurality of first to third filters (80, 82, 84) thereon, the pressure fluid is discharged to the outside.
