Claims

[Claims for Utility Model Registration] 1. A pipe line 1b between the pressure supply side and the load actuator is provided with a chamber 3e communicating with the pipe line and another chamber 3a open to the atmosphere. , a seat 3C is cut between the chamber and the other chamber toward the other chamber, and a valve is inserted into the seat from the other chamber toward the chamber by an energizing force. 3d, the valve is configured to be interlocked with the movement of the lever 4, and the interlocking is configured such that the movement of one of the levers causes the valve to rise from the seat against the urging force. A switching valve with a relief action featuring a summer loop. 2. The structure of the lever 4 is such that a part of the lever is pivotally attached to the pin 4a, so that it can swing around the pin, and the structure of the valve 3d is such that a stem is fixed to the valve. 3f is exposed to the outside of the chamber 3e, and the structure in which the valve and the lever are interlocked is such that the lever presses the stem when the lever swings. I described in scope item 1
A switching valve with J IJ-F action. 3. A switching valve having a relief function as set forth in claim 1 or 2 of the utility model registration claim, wherein the biasing force is the spring force of the spring 3b.
