<p>The gear boxes (10,110) have high-pressure system (18) which is partly filled with gear box fluid with a first pressure. The low pressure systems (20,120) are partly filled with gear box fluid with a second pressure lower than first pressure. The diffusers (30,130) in fluid communication with the high and low pressure systems, are provided with inlets (32,132) for receiving transmission fluid from high pressure system, and outlets (34,134) for discharging the transmission fluid to the low pressure system. The cross sectional area of the outlet of the diffuser is greater than the cross sectional area of inlet of diffuser.</p> |
