CONTROL VALVE
3J0AX00
The pressure in chamber C drops below that in chamber
B, causing the pressure to become unequal. This causes
the main poppet (6) to open up, which allows the pres-
sure oil to flow to the tank passage T.
When the valve is engaged in valve suction opera-
tion:
If the cylinder is operated at a speed too fast for the oil
supply to keep up, and thus the pressure of the chamber
B becomes almost negative, oil is supplied from the tank
to prevent cavitation.
When the pressure in chamber B is lower than the pres-
sure in the tank passage T, the difference in cross-sec-
tional areas between A and A1 causes the main poppet
(6) to open. This, in turn, causes oil to enter from the tank
passage T to fill in the empty space in the chamber B.
