Abstract
A buoyancy control device for divers includes a plurality of inflatable members each adapted to be inflated to a predetermined maximum volume, or to be deflated, and a fluid distributor for selecting the inflatable members to be inflated and to be deflated, thereby controlling the buoyancy of the device. The fluid distributor includes a housing having an inlet port connectible to a source of pressurized fluid, a venting port leading to the atmosphere, and a plurality of outlet ports connected to the inflatable members. A flexible membrane overlies a grooved surface in the housing, and a valve member is movable over the membrane to press it into the groove such as to effect the communication between the inlet and venting ports with respect to selected outlet ports.
