HYDRAULIC SYSTEM

DV1
:
Solenoid valve (NO).
F
UNCTION
:
- Dumping of the oil flow supplied by the main
hydraulic power unit (if not actuated).
- Divertion of the oil flow to the boosting circuit of the
wheel motors during the stopping phases of the drive
movements.
A.
Check valve (0,05 MPa)
F
UNCTION
: Prevents the oil flow suplied by the hand
pump from returning to the reservoir during operation
using the breakdown controls.
NOTE
The check valve is kept in position by
deformation of the thread : cannot be
removed.
B.
Check valve (0,45 MPa)
F
UNCTION
: Provides a necessary counter pressure in
the boost circuit. Limits the oil return of the make up
flow diverted by the solenoid valve [DV1].
C.
Jet Ø 1 mm
F
UNCTION
: Ensures decompression of the pilot circuit
of the counterbalance valve on the mast cylinder
(lowering movement).
NOTE
The jet is installed with glue : cannot be
removed.
