摘要： A lubrication circuit for a gas turbine engine includes a bearing compartment, an air inlet connected to the bearing compartment, a lubricant inlet, and a lubricant outlet. The air inlet fluidly connects the bearing compartment to an environment external to the compartment. The lubricant inlet and outlet are connected to the bearing compartment. A scavenge valve is operatively connected between the lubricant outlet and a scavenge pump that is responsive to bearing compartment pressure for controlling pres sure drop across the air inlet.
