ABSTRACT:
A dual lid assembly for closing first and second coupled openings, has entirely separable first and second lids for closing fluid-tight the first and the second opening, respectively. The dual lid assembly further includes a lid connecting device for coupling fluid-tight the two lids to one another; a first actuating device coupled to the lid connecting device for operating the latter by an externally-applied force; a lid locking device for tightening the first lid to a wall defining the first opening; a second actuating device coupled to the lid locking device for operating the latter by an externally-applied force. The second actuating device includes an actuating element connected to the lid locking device and displaceable parallel to the axis of the first lid. There is further provided a bearing unit attached to the first lid in the center thereof; an actuator pin attached to a mid portion of the actuating element and slidably supported in the bearing unit. The actuator pin has a terminus projecting outwardly of the bearing unit and oriented away from the attachment between the actuator pin and the actuating element. A spring contained in the bearing unit and engaging the actuator pin urges the latter outwardly from the bearing unit in the direction of the pin terminus. The actuator pin and the spring form part of the second actuating device. A seal supported in the bearing unit and surrounding and engaging the actuator pin ensures that the actuator pin passes through the bearing unit in a sealed manner.
