ACCUMULATOR OF A HYDRAULIC STRIKING SYSTEM FOR MOLDING AND COMBINING A METAL OR NON-METAL PLATE WITH ELASTIC BENDING AND TENSILE STRENGTH LARGER THAN A DIAPHRAGM IN A FLUID INLET SURFACE OF THE DIAPHRAGM

摘要

PURPOSE: An accumulator of a hydraulic striking system is provided to prevent a boundary surface between a diaphragm and a metal or non-metal plate from being deformed and to absorb effectively shock pressure of the working fluid by making the diaphragm thin. CONSTITUTION: In an accumulator of a hydraulic striking system, an accumulator body(110) is branched and connected to a pipe through a fluid inlet port(120). A diaphragm(150) divides the inside of the accumulator body into a fluid inlet chamber(130) of the fluid inlet port and a gas chamber(140) in the opposite side. A diaphragm(150') of the fluid inlet port of the flexible diaphragm is thick. A metal plate(170) having an inclined end(160) at the periphery is molded and combined in the diaphragm of the fluid inlet port to restrict a radial deformation in a boundary surface between the diaphragm and the metal plate.
