Abstract:
1. A valve system, comprising: (a) first and second longitudinally facing members defining a gap therebetween in fluid communication with transversely offset first and second orifices through the members, wherein one of the members is longitudinally repositionable relative to the other member for adjusting the longitudinal height of the gap, (b) a primary biasing means longitudinally biasing the members away from one another, (c) an elastic element positioned within the gap between the first and second orifices, (d) a repositioning means for longitudinally repositioning the repositionable member towards the other member against the bias of the primary biasing means as between (i) a first position wherein the elastic element does not seal the gap so as to allow fluid flow from the first orifice to the second orifice through the gap, and (ii) a second position wherein the elastic element is compressed between the members and seals the gap so as to prevent fluid flow from the first orifice to the second orifice through the gap.
