FUEL FLOW LIMITER ASSEMBLY HAVING INTEGRAL FUEL FILTER AND FUEL SYSTEM USING SAME

Abstract:

A fuel flow limiter assembly includes a limiter body forming a central bore, and including a shutoff piston within the central bore having a closing hydraulic surface exposed to a fluid pressure of the fuel inlet, and being movable from an open position, to a closed position based on a fuel pressure drop from a fuel inlet to a fuel outlet in the limiter assembly. A fuel filter is resident in the limiter assembly and supported in a connector coupled to the limiter body. The fuel filter is elongate and projects from the connector into a fuel flow path from the fuel inlet to the fuel outlet.
