Abstract
An exemplary apparatus for supplying lubricant to a gear assembly in a gas turbine engine includes a valve having a valve inlet configured to be coupled to a source of lubricant. A valve outlet is configured to direct lubricant to the gear assembly. The valve is selectively controllable into a plurality of settings for varying an amount of lubricant flowing from the valve inlet to the valve outlet. A bypass is associated with the valve. The bypass has an inlet configured to receive lubricant from the source and an outlet configured to direct lubricant to the gear assembly. The bypass permits at least a selected amount of lubricant to flow to the gear assembly independent of a setting of the valve.
