Dump
1. When the hydraulic control lever is set to the
"DUMP"
position, the spool (3) of the bucket control section (2)
moves to the right, which forms oil passages between passage 2 (9) and
A2
port, also between
B2
port and
T
port.
2. The pressurized oil from the
P
port flows to the neutral passage 2 (10) through the boom control section (1) and
PB
passage 1 (5).
As the oil passage from the neutral passage 2 (10) to the
PB
passage 2 (6) is closed by the spool (3), this oil
opens the load check valve (7) and flows through the notched section of the spool (3) and
A2
port to extend the
bucket cylinder (11).
3. Return oil from the bucket cylinder (11) flows to the transmission case through the
B2
port and
T
port.
