Control piston (10) diameter is larger than counter piston (4) diameter, the oil pressure that is
acting against control piston (10) overcomes the force of counter spring (6). The oil pressure than
causes the pump to destoke.
Pressure and flow compensator valve (7) also controls the maximum output of pump pressure.
When steering and loader pressure rises above pressure compensator setting, pressure
compensator spool (12) overrides flow compensator spool (13). This causes the pump to
destroke.
