ABSTRACT:
A buoyancy compensator having a combined capability. The combination is in part provided by a pressure relief valve having a spring loaded valve plate for closing off the interior of the buoyancy compensator. The buoyancy compensator has a hand actuated inflation apparatus which receives a tube connected at its other end to a source of gas under pressure such as a first stage regulator. The tube or hose is inserted in the apparatus and is partially valved by a Shrader type valve configuration in an end fitting thereof. The vest is provided with a plug and fitting wherein the inflation apparatus can be utilized optionally by subsequent implacement or retrofitting the vest with the inflation apparatus. The buoyancy compensator vest also incorporates an oral inflator which utilizes a plunger operated valve for filling the vest. In cases of emergency, a charged bottle of gas can be punctured to fill the vest to allow a diver to rise rapidly to the surface. The entire vest is made of an outer textile material which serves to prevent the expansion of a non-adhered free bladder beyond a fixed point therein. The vest and combination are attached to the body by straps around the waist, over the back, or through the legs.
