Claims6
A raft inflation valve assembly comprising:
- (a) a tubular body member adapted to be mounted in fixed relationship with a raft bladder and having a central bore defined by an interior surface having an upper opening exterior of said raft bladder and a lower opening interior of said raft bladder;
- said tubular body member comprising a first annular lip surface defining a portion of said central bore and a second annular lip surface defining a portion of said central bore;
- (b) a plunger member for coacting with said valve body member, for alternately placing said inflation valve assembly in an open state and a closed state;
- said plunger member being received in said tubular body member bore and having a shaft portion having a first end which is adapted to engage said first lip portion for maintaining said inflation valve assembly in said open state and having a base portion which is adapted to engage said second lip portion for placing said inflation valve assembly in said closed state;
- and
- (c) biasing means for biasing said plunger member upwardly within said valve body bore.
