METHOD FOR REDUCING NOISE USING ELASTIC MOUNT INSTALLED IN MAIN CONTROL VALVE BY MOUNTING

摘要

PURPOSE: A method for reducing noise using an elastic mount installed in a main control valve by mounting is provided to block or reduce noise delivered to a cabin by reducing the pulsating transmission noise delivered to a MCV. CONSTITUTION: An elastic mount(5) supports the frame and the lower part of a main control valve(MCV,4). A fluid borne noise stays at the main control valve which delivered through fluid which is moved in a rubber hose(3). The fluid borne noise is generated in a hydraulic pump(2) which is connected to the engine(1) of the construction heavy equipment.
