Abstract
The invention is a shut-off seal assembly for use with the drive assembly of fluid-containing vessels. The shut-off seal assembly first locks the seal carrier of the drive assembly in place so that it may not rotate in a clockwise or a counter-clockwise direction. The seal carrier includes a pair of notches into which a pawl may be fitted preventing seal carrier rotation. The seal carrier surrounds a sleeve which includes a plurality of slots. A backwards rotation of the drive shaft causes drive pins to slide in the angled slots, thereby causing the seal element to move forward and create a seal between the drive assembly and the vessel.
