PRESSURE-RIPPLE REDUCING APPARATUS OF A HYDRAULIC SYSTEM, CAPABLE OF MINIMIZING THE CONSTRUCTION AND VOLUME OF A VIBRATION AND NOISE REDUCING DEVICE

摘要

PURPOSE: A pressure-ripple reducing apparatus of a hydraulic system is provided to effectively process various frequencies of pressure ripples in a wide range. ;CONSTITUTION: A pressure-ripple reducing apparatus of a hydraulic system comprises a fluid flow pipe(110) and a resonant pipe(120). Fluid flows along the fluid flow pipe. The resonant pipe is arranged on a position separated from the fluid flow pipe. A plurality of resonant holes are formed on one side of the fluid flow pipe. The resonant holes have different diameters.;COPYRIGHT KIPO 2011
