Oil circuit – hydraulic system
Gearbox hydraulic pressure sender
G270 and pressure limiting valve
Hydraulic pressure sender
Pressure limiting valve
The hydraulic pump pumps the hydraulic oil through
the filter towards the pressure limiting valve, the
pressure accumulator and the hydraulic pressure
sender.
When the hydraulic oil pressure at the pressure
limiting valve and the hydraulic pressure sender
reaches approx. 70 bar, the control unit switches the
electric motor and therefore the hydraulic pump off.
The bypass ensures that the system functions if the
filter channel is clogged.

Pressure accumulator
Pressure accumulator
The pressure accumulator is designed as a gas
pressure accumulator.
It provides the hydraulic system with oil pressure
when the hydraulic pump is switched off.
Its storage volume is 0.2 litres.
