Gear pump bearing with hybrid pad shutoff

A fuel pump system for a gas turbine engine comprising:

• a fuel tank connected to an inlet side of a gear pump, and a discharge side of said gear pump connected to a combustor of a gas turbine engine;
• the gear pump including a first gear intermeshed with a second gear;
• the first and second gears defining said inlet side, and said discharge side, at least one shaft in operable communication with each of the first and second gears;
• a bearing configured to support at least one of the at least one shafts via an inner bore and having an outer peripheral surface, a valve bore being formed into said bearing between said inner bore and said outer peripheral surface, said bearing defining a second discharge connection, a tap providing fluid from aid discharge side through the valve bore and to a pad defined in said inner bore:
• and
• a valve positioned in said valve bore and having a moving member, and a spring biasing said moving valve member in a direction toward the second discharge connection, and said moving valve member allowing or limiting flow from the second discharge connection reaching said pad as a pressure on said second discharge connection varies.

• and a valve positioned in said valve bore and having a moving member, and a spring biasing said moving valve member in a direction toward the second discharge connection;
• wherein said spring biases said moving valve member to a closed position, and an inlet connection is also provided to said inlet side of said gear pump to bias said valve member in combination with said spring;
• and,
• wherein said moving valve member selectively allows flow from a third discharge connection in a direction generally perpendicular to a direction of valve movement.
