<p>PURPOSE:To prevent damage of a diaphragm in a shock absorbing accumulator and provide ready assembling of the accumulator by directly communicating a pipe with a pressure container via a fluid passage and providing an annular valve body at the diaphragm for effectively absorbing the impact. CONSTITUTION:A pipe 1 is mounted at the holes 4, 7 of a pressure container A to make the container A pressure contact with step 2 by screwing a nut 29 into the threaded portion 3 of the pipe 1 thus externally mount the pipe at the container A. Since the pipe 1 is communicated with one chamber a of internal chambers a, b divided by a disphragm 18 to thereby introduce liquid through the pipe 1 into the chamber a, predetermined pressure gas is sealed in the other chamber b against the standard pressure of the liquid. When the annular valve 27 is is mounted at the diaphragm 18 in response to the annular valve seat 26 to close the hole 25 to make pressure contact with the seat 26 when the liquid pressure is lowered to cause the diaphragm 18 to move toward the main body 9.</p> |
