(4) Check and High Pressure Relief Valve
The check and high pressure relief valves monitor the
oil pressure in each line of the main oil circuit.
In neutral, both check valves are open and charging
oil enters into the main oil circuit through the valves.
At normal operation, the check valve in the high
pressure side is closed and it pushes and opens the
another one.
When excessively high pressure is built up in one line,
the high pressure relief valve located in this line is open
and the oil flows into another line.
