Claims (1)

[Scope of utility model registration request] A main spool which is hollow and whose ends are closed is slidably fitted into a valve body which is hollow and whose ends are closed, and a plunger whose left end is open and whose right end is closed and a relief spool slide into the main spool. In a flow divider valve that is freely and continuously fitted, a first orifice and a second orifice are provided in the plunger to communicate a pressure fluid inlet hole provided in the valve body with a control fluid outlet hole, and the pressure of the control flow is controlled. A diversion valve characterized in that, when the flow exceeds a certain level, a relief passage is provided in the relief spool that communicates a control outlet hole with a relief outlet hole provided in a valve body, and the flow divider valve is configured to close a first nitrogen orifice.
