摘要 |
Pressure controlling valve mounted in such a manner as to be directly inserted between a change valve and a base and which has a valve body which is substantially equal to the change valve in width. In the valve body, there are provided a plurality of communication channels that communicate the corresponding ports of the change valve and base, a pressure control valve port that crosses those channels, a pressure control valve stem inserted in the port, and a controlling mechanism which are under a set pressure in cooperative action with the stem. The channels to guide pressure fluid for controlling pressure include a lead port inside the pressure controlling valve step and a lead clearance in the outer region of pressure controlling valve stem.
