    • A seal for preventing leakage of pressurized fluid along a flow path along an engagement plane between a first and second members. The seal has a cylindrical body with a first elastomeric ring located on an end and a second elastomeric ring located on a peripheral surface of the cylindrical body. The cylindrical body is located in a passage in the second member. A spring urges the first elastomeric ring into engagement with a face on the first member when the first and second members are joined together. Pressurized fluid which flows from a passage in the first member into the second passage in the second member acts on the cylindrical body to further urge the end into engagement with the first member to prevent fluid leakage along the engagement plane there between.

    • A combination pressurizing valve (27) and fuel flow divider for a gas turbine is operable in three different fuel distribution modes utilizing three windows which are successively opened to control the flow distribution to the engine atomizing or start-up nozzles (23) and engine air blast or running nozzles (25) respectively by way of two fixed orifices (51, 55) in a way that satisfies the start-up flow distribution favoring the atomizing nozzles (23) as well as the need for balanced flow distribution between the different types of engine nozzles after a successful start. The first window position corresponds to an engine ignition mode and includes a range of intermediate valve spool (33, 133) positions where one outlet port (57) is open and the other outlet port (67) receives a restricted flow of fuel. The second window position includes a range of valve spool (33, 133) positions where the one outlet port (57) is open and the other outlet port (67) is open to receive a flow of fuel greater than the restricted flow. The third window position corresponds to a full power engine condition and includes a range of valve spool (33, 133) positions including the another extreme position where the one outlet port (57) is open and the other outlet port (67) is open to receive a still further increased flow of fuel.

    • A fuel flow dividing ecology valve conveys fuel from a fuel source to at least a secondary gas turbine engine intake manifold during engine operation and withdraws fuel therefrom upon cessation of engine operation. The valve includes a flow dividing valve portion having an inlet coupled to the fuel source and an outlet coupled to the secondary manifold. The valve also includes an ecology valve portion controlled by the fuel pressure differential between the fuel source and the flow restricting inlet. The ecology valve portion includes a housing with a movable piston disposed therein. The piston defines, in conjunction with the housing, a variable volume chamber for withdrawing fuel from the engine intake manifolds. When the engine is de-energized, the piston moves from a first position toward a second position thereby purging the manifolds of fuel.
