Vibratory System Circuit Diagram - ON - LOW AMPLITUDE.
(1) Vibratory motor. (2) Flushing relief valve. (3) Oil line from propel cooling valve. (4) Closed circuit loop line. (6) Servo piston assembly. (8) Oil line
from hydraulic oil filter. (9) Vibratory pump. (10) Vibratory flushing valve. (11) Closed circuit loop line. (12) Check valve. (13) Hydraulic oil tank. (14)
Vibratory amplitude valve. (16) High pressure relief valve.
Vibratory servo valve (14) receives an electrical input when the
vibratory control switch is in the ON position and the vibratory
selection switch is moved to the LOW AMPLITUDE position.
The electrical input causes the vibratory amplitude valve to
move from centered position and allows charge oil from oil line
(8) to pass across the relief valve to servo piston assembly (6),
moving the swashplate to maximum angle for low amplitude.
The vibratory selector switch controls the direction of
swashplate angle by sending current to one of the vibratory
pump servo valve coils.
High pressure oil delivered from vibratory pump (9) flows into
closed circuit loop line (11). The high pressure oil drives
vibratory motor (1). Low pressure oil from the vibratory motor
flows back to the vibratory pump through closed circuit loop
