Oil in at
V1
.
The shuttle valve
C
opens and permits
oil flow to measuring point
E
and to the
brake
F
which releases when the
pressure exceeds 30 bar.
The pilot line
G
leads oil to the Over
Centre Valve
D
. This valve opens at
approximately 60 bar so that oil from
the motor can return to the tank.
The oil drives the motor
M1
and
passes through the Over Centre
Valve
D
and to
V2
.
(Red lines in the circuit diagrams = oil flow. Green lines = only pressure).
