System for lubricating components of a gas turbine engine including a lubricant bypass conduit

A gas turbine engine, comprising:

• a compressor section;
• a combustion section;
• a turbine section;
• one or more lubricated components provided in operative association with at least one of the compressor section, the combustion section, or the turbine section;
• a reservoir configured to store a lubricant;
• a supply conduit extending from the reservoir to the one or more lubricated components of the gas turbine engine;
• a supply pump configured to pump the lubricant from the reservoir through the supply conduit;
• a scavenge conduit extending from the one or more lubricated components to the reservoir;
• a scavenge pump configured to pump the lubricant from the one or more lubricated components through the scavenge conduit;
• a valve fluidly coupled in series with the scavenge conduit, the valve being unable to control a flow of the lubricant through the supply conduit;
• and
• a bypass conduit extending from the valve to a location on the supply conduit downstream of the supply pump,
• wherein:
• when the lubricant is supplied from the reservoir to the one or more lubricated components, the valve directs the lubricant flowing through the scavenge conduit into the reservoir;
• and
• when the supply of lubricant from the reservoir to the one or more lubricated components is halted, the valve directs the lubricant flowing through the scavenge conduit into the bypass conduit.
