Abstract:
1. A closure system for a fluid outlet, the system comprising: a motor connected to a threaded shaft that passes through and is enmeshed with a threaded hole of a hub, the threaded hole extending through the hub to a recess disposed within the hub, the hub being connected to a closure for covering the fluid outlet, the hub also comprising an abutment, the hub further comprising a curved slot coaxial with the threaded hole and spaced radially outwardly therefrom, the curved slot terminating at two circumferentially spaced apart ends, the curved slot accommodating a stationary pin that permits a partial rotation of the hub about an axis through the threaded hole, the shaft being connected to a biasing member that engages the stationary pin and the hub and which biases the hub towards a position where the stationary pin engages one of the ends of the curved slot with the closure covering the fluid outlet, the threaded shaft also being connected to a radially outwardly extending finger, the motor rotating the shaft within the threaded hole of the hub resulting in axial movement of the hub and closure away from the motor and fluid outlet respectively and rotating the finger towards the abutment and, when the finger engages the abutment, continued rotation of the shaft overcomes the bias of the biasing member resulting in partial rotation of the hub and closure to a position where the stationary pin engages the other of the ends of the curved slot with the closure being rotated away from the fluid outlet.
