Title:
流れ分岐装置及びエコロジー弁
Document Type and Number:
Japanese Patent JP2005530951
Kind Code:
A
Abstract:
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.
