Filed:

May 29, 2001

Appl. No.:

09/867359

Inventors:

Raymond D. Zagranski - Somers CT
Roger Lapointe - Feeding Hills MA
William H. Dalton - Amston CT
Frank M. Amazeen - West Hartford CT

Assignee:

Goodrich Pump and Engine Control Systems, Inc. - Charlotte NC

International Classification:

F04B 4900

US Classification:

417220, 91 3, 137503

Abstract:

A fuel metering unit including a pump having a rotor with a plurality of slots. The pump also includes a pivotally movable cam ring coaxially arranged with respect to the rotor. Vanes are slideably disposed in the slots for maintaining contact with the cam ring during movement thereof. A servovalve has a motor and nozzles operatively connected to the pump such that increased flow through the first nozzle pivots the ring of the pump toward maximum while increased flow through the second nozzle pivots the ring toward minimum. An arm extends between the nozzles for varying fluid flow therethrough. The arm couples to the motor such that the motor moves the arm. A flow meter connects to the pump and an end of the arm for applying a force against the arm to assist in maintaining position of the arm.
