Flexible seal and groove assembly

A seal and groove assembly in combination with a pair of members to be sealed against the movement of fluid therebetween, said assembly comprising

• (a) a lateral groove in one of said members having defining side and bottom walls and having an opening directed toward said other member,
• (b) a flexible seal having opposite ends,
• (c) said seal being mounted in said groove and having one seal end portion thereof projecting through said opening for end sealing engagement with said other member,
• (d) said seal having a sinuous-like portion between its ends arranged to be flexed toward a straightened condition upon being subjected to a pressured fluid to cause said one seal end portion to forcefully seal against said other member,
• (e) and at least one fluid escape port in one of said pair of members communicating between said lateral groove and a low pressure side of said assembly to drain any trapped downstream fluid.

• (c) said seal being mounted in said groove and having one seal end portion thereof projecting through said opening for end sealing engagement with said other member, said seal having a sinuous-like portion between its opposite ends,
• (d) said lateral groove and said sinuous-like portion being arranged so that a projecting part of the sinuous-like portion of said seal upon being subjected to a pressured fluid abuts against at least one side wall of said groove and pivots about the said projecting part causing the said seal to flex toward a straightened condition to cause said one seal end portion to forcefully seal against said other member.

• (a) a lateral groove in one of said members having defining side and bottom walls and having an opening directed toward said other member,
• (b) and a seal comprising a flexible body member having opposite end portions and opposite sides,
• (c) said seal being mounted in said groove,
• (d) one of said end portions of said seal being in abutting engagement with one of said defining walls of said groove and the other of said end portions of said seal projecting through said opening for end sealing engagement with said other member,
• (e) said body member having a sinuous-like portion between its opposite ends arranged to be flexed toward a straightened condition upon being subjected to a pressured fluid from one side thereof to cause said other of said end portions to forcefully seal against said other member.
