From continuous rotating to deceleration
At deceleration, the motor is still rotated by inertia. The oil flows M2 port to P2 port during
counterbalance valve is opened. Then, if the flow to P1 is not enough, the cavitation could be
appeared in P1-M1 line.
Anti cavitation valve can make a oil passage like M2 C spool A P1 M1 and supply
flow before counterbalance valve spool is returned. Consequently the cavitation is reduced by the
above function.
