  • Fluid noise muffler and method of manufacture
    Patent number: 5426270
    Abstract: A muffler for reducing fluid flow noise in a hydraulic system comprises a cylindrical elastomer insert having multiple reinforced flow ports with different diameter porting, internal air chambers, and cast from an elastomer mixed with hollow glass spheres to form an insert of 40 percent air by volume. The insert is placed within a housing and connected to the hydraulic pipe assembly for receiving fluid under pressure and diverting it through the multiple flow ports of the insert wherein flow sounds, pump surges, and flushing noises of the hydraulic system are muffled by the disruption of the flow through the flow ports, the absorption by the internal air chambers, and the absorption by microspheres created by the hollow glass spheres in the elastomer insert.
    Type: Grant
    Filed: July 6, 1993
    Date of Patent: June 20, 1995
