Lubricating pressure, function - GF27.60-P-3014G

TRANSMISSION 722.6

Operation

The working pressure regulating valve diverts surplus oil to the lubrication pressure regulating valve, from where it is controlled and used for lubricating and cooling the mechanical transmission and torque converter. In addition the pressure in the torque converter is limited via the lubrication pressure.

TRANSMISSION 722.9 in MODEL 463.303 /340 /341

Excess oil is diverted to the lubrication pressure regulating valve at the working pressure regulating valve and from there used in a regulated manner for lubricating and cooling the mechanical transmission parts and torque converter. In addition the pressure in the torque converter is limited via the lubrication pressure.

Lubrication pressure regulating valve, function - GF27.60-P-5122-01G

Transmission 722.6

Operation

At the working pressure regulating valve (22) surplus oil is diverted to the lubrication pressure regulating valve (23), from where the lubrication pressure (p-Sm) is used in regulated amounts to supply the transmission lubrication system including the torque converter.
