The invention discloses a vibration feedback and force feedback combined man-machine interaction finger, glove and method and belongs to the technical field of man-machine interaction wearing. The data glove provided by the invention is fixed to the hand back of a user, it is ensured that the palm can freely expand and clench, a novel connecting rod mechanism is adopted, thus excessive burdens cannot be generated on the hand, and the flexibility of the finger can also not be influenced. Through combination of vibration feedback and force feedback methods, single sense organ paralysis caused bylong-time use by the user is avoided; the force feedback method adopting rope driving is safer than a method directly adopting a motor for driving, and vibration feedback generated by the vibration motor cannot oppress the hand because the motor is small in size; and the whole glove is designed in a non-full-covering mode, only the portion, needing to be stimulated, of the hand is covered, and thus resonant interaction is reduced. The whole vibration feedback and force feedback combined man-machine interaction glove is simple in structure, low in manufacturing cost, capable of being manufacturing through common 3D printing, and convenient to wear and popularize in user groups.

An exhaust valve assembly includes a flapper valve fixed to a valve shaft where the flapper valve is movable between a closed position, an intermediate position, and an open position. A resilient member biases the flapper valve toward the closed position. An electric actuator actively moves the flapper valve at least from the closed position to the intermediate position. A coupling mechanism couples the valve shaft to an electric actuator shaft and allows the flapper valve to move to the open position in response to exhaust flow sufficient to overcome a biasing force of the resilient member without requiring input from the electric actuator.
