The hydraulic unit

• Solenoid valves of which each wheel has an intake solenoid and an exhaust solenoid valve.

• Pressure accumulators that are pressurized gas reservoirs used to provide a large flow rate for a short period of time.

The ECU

As soon as a wheel tends to lock up, it guides the solenoid valves and hydraulic pump.

The hydraulic motor

It uses the oil flow that is pushed into the hydraulic circuit by a hydraulic pump and transforms it by a rotary motion to drive another device such as for example the differential or the fan, etc.
