  • This movement pushes hinge 168 away from threaded screw member 170 to release plates 82 , 84 in a folding action from seal 202 to open the fluid control barrier.
  • the net force in opening or closing the plates 82 , 84 is minimal and largely those associated with the frictional force in moving the hinge 168 by struts 186 , 188 .
  • Struts 190 and 192 and struts 196 and 198 will be drawn towards one another as shown in FIGS. 76 and 78 .
  • the positioning of the struts 190 , 192 , 196 and 198 on plates 82 , 84 with a slight location bias either side of the centroidal axis can result in a resultant force with a bias towards either self closing or self opening depending on what side of the axis is the location of the pivotal connection of the struts 190 , 192 , 196 and 198 .
  • a similar result can be obtained by offsetting the mounting point of the struts 190 , 192 , 196 and 198 above the surface of said plates 82 , 84 and slightly away from the centroidal axis.

From the position shown in FIGS. 79 and 81 the axles 156 are rotated causing the linear drive members 12 to pull hinge 168 axially away and pull struts 186 , 188 towards each other. This movement pulls hinge 168 to release plates 82 , 84 in a folding action from seal 202 to open the fluid control barrier. Struts 190 and 192 and struts 196 and 198 will be pulled towards one another as shown in FIGS. 80 and 82 .
