Abstract: A mechanical multiplier (25) in a fuel control for a gas turbine engine has a first track member (26) mounted for lateral movement and a first axially movable displacement member (34) connected to the first track member. A second track member (42) is mounted adjacent the first track member for pivoting movement about an axis (52). A follower assembly (54) operatively interconnects the track members and has rollers (120,122) respectively received in the tracks of the first and second track members. A second displacement member (55) is connected to the follower assembly for movement generally perpendicular to the direction of lateral movement of the first track member. The second displacement member is connected to the output piston (65) of a pressure transducer (66) which senses compressor discharge pressure; and the first displacement member is operatively connected to a fuel metering valve (100).
