Abstract
A hydraulic thrust reverser system (TRAS) including a first return line having a first check valve therein, and a second return line having a second check valve therein, wherein the first return line and the second return line are in fluid communication with each other via a fluid restrictor located upstream of the first and second check valves, wherein the first return line extends from a piston system of the TRAS, the piston system being for moving at least one thrust reverser door, and wherein the second return line extends from a lock system of the TRAS, the lock system being for controlling locks to selectively prevent the movement of the at least one thrust reverser door.
