ABSTRACT:
Method and apparatus for reduction of fluid borne noise in a hydraulic system are disclosed. An improved isolating hose assembly comprising first, second and third volumetrically compliant members with first and second inductive flow members providing fluidic coupling therebetween is disclosed. The improved isolating hose assembly acts similarly to an electronic low pass filter network in deterring fluid borne noise from entering portions of the hydraulic system located therebeyond. A modified isolating hose assembly comprising a resistive member introduced within the second volumetrically compliant member in order to eliminate the possibility of a deleterious resonance in the assembly is disclosed. In addition, apparatus for additionally reducing structure borne noise in hydraulic systems comprising direct hydraulic coupling of the first volumetrically compliant member to internal output ports of the hydraulic system's pump is disclosed.
