Abstract: A hydraulic actuator that is capable of substantial actuation but does not require a conventional pump, uses only deflectable membranes and passive valves, or, at most, a minimum of active valves, and, under certain circumstances, may be free to move when the actuator is de-energized, is provided. The actuator utilizes the deflectable membranes to move fluid throughout the actuator. The movement of the fluid actuates a shaft or other suitable device, as required.

Abstract: A positive locking device is provided in order to prevent a motor from rotating after power has been removed. The positive locking device has a plate mounted on the motor which engages a disk or hub on the shaft of the motor. In another aspect of the invention, solid state circuitry for switching a permanent magnet motor and providing dynamic braking thereto is provided. The circuitry allows the back EMF generated by the armature coils of a permanent magnet motor to cause a current to flow through the motor when power is removed. This back EMF may be used to help produce smooth engagement of the locking device. In another aspect of the invention, a dynamic braking circuit for a dual armature permanent magnet motor is provided. By applying current to one or the other of two oppositely wound armature coils the motor is made to rotate in either direction. When power is removed from the active armature, this armature is short-circuited through a diode. The same diode is used to dynamically brake the motor when power is removed from the other armature. In both cases the spinning rotor will quickly slow down to facilitate smooth engagement of the positive locking device.

Abstract translation: 提供了一种正向锁定装置，以便在电力消除之后防止电动机旋转。 正锁定装置具有安装在电动机上的板，其接合电动机的轴上的盘或轮毂。 在本发明的另一方面，提供了用于切换永磁电动机并提供动态制动的固态电路。 该电路允许由永磁电动机的电枢线圈产生的反电动势在掉电时使电流流过电动机。 该反电动势可以用于帮助产生锁定装置的平滑接合。 在本发明的另一方面，提供了一种用于双电枢永磁电动机的动态制动电路。 通过将电流施加到两个相对缠绕的电枢线圈中的一个或另一个上，使电动机沿任一方向旋转。 当从有源电枢移除电源时，该电枢通过二极管短路。 当从另一个电枢移除电源时，使用相同的二极管来动态地制动电动机。 在这两种情况下，旋转转子将快速减速以促进正锁定装置的顺利接合。

Abstract: A flight lock actuator that can be powered by two sources of stored energy when aircraft power has been switched off. A mechanical energy storage means and an electrical energy storage means provide a fully redundant energy storage system that stores sufficient energy to complete the actuator's extension stroke when aircraft power is removed. The actuator has a motor control system that limits the stroke velocity for both the extension and retraction strokes, including a damper feature capable of effectively braking the actuator during the back-driven extension stroke.
