DESCRIPTION

The power steering system reduces the effort at the steering wheel in manoeuvres at a standstill and keeps steering precise at high speeds.

The system comprises a pump (1) operated directly by the engine through a belt. The pump withdraws oil from the reservoir (2) in the engine compartment through the inlet pipe and sends it under pressure through the delivery pipe to the distributor valve on the power steering box (3).

The distributor valve, which is controlled by the turning of the steering wheel, sends the oil under pressure from one side or the other of the hydraulic cylinder which is integral with the rack and pinion, inside the steering box.

A section of the return pipe to the reservoir is positioned in front of the radiator and it is struck by the cooling air to remove heat and keep the hydraulic fluid at the correct temperature level.
