ABSTRACT:
A gas turbine engine oil system is provided in which the centrifugal separator is arranged to act as a pump for supplying bearing chambers directly, and the scavenging of the bearing chambers is achieved primarily by the pressurization air which flows into the chambers to prevent oil leakage. To avoid the use of pressure regulating valves for controlling the oil flow an oil tank is pressurized and communicates with an auxiliary outlet from the separator, the pressure in which is governed by the quantity of oil flowing around the system. The tank and the bearing chambers are fluidly connected to the centrifugal separator in two separate fluid circuits with each circuit having the separator as an element thereof.
