ABSTRACT:
Method and improved apparatus for reduction of fluid borne noise in a hydraulic system are disclosed. A shortened noise suppression assembly comprising first, second and third volumetrically compliant members with first and second inductive flow members providing fluidic coupling therebetween is disclosed. The shortened noise suppression assembly acts similarly to an electronic low pass filter network in deterring fluid borne noise from entering portions of the hydraulic system located therebeyond. At least one of the first and third volumetrically compliant members are comprised within a stub line. The remaining one, or ones, of the first, second and third volumetrically compliant members, and the first and second inductive flow members form conduit members of a passage for connecting a pump to the portions of the hydraulic system located therebeyond.
