<p>PROBLEM TO BE SOLVED: To perform the installation with a pipe system setting route standardized independently from battery cell form by providing a plurality of pipe system connectors for fluid communication on a replenishing valve, and providing at least three pipe connecting ports on substantially all of the pipe connectors. SOLUTION: Each of pipe system connectors 20 has the same form and dimension, and comprises extensions for forming three ports. A generally used clamp ring surely connects the connector 20 to a pipe system 27, enclosing the extensions. A swollen part on the upper part of the extension imparts a sitting position to the pipe system 21 and stops its further movement. Each extension is preferably set so as to be right-angled to the adjacent extensions and T-shaped when the pipe system connector 20 is seen from above. An insert body is pushed into the port not connected to the pipe system 27 by a finger to block it.</p> |
