Abstract:
Aquatic structures with adjustable buoyancy constructed in part with a vent valve for a buoyancy control device suitable for divers, where the vent valve may be opened by any combination of over-pressure, manual pressure relief or a powered means, where a force to a valve plug is applied by means of a spring that is constrained to prevent entirely lateral and angular movement but in which movement of the plug in the axis of the seat is unconstrained.

Claim (Index 1):
An aquatic structure comprising:\n a mechanical structure; a control unit attached to the mechanical structure, the control unit including: at least one of a plurality of sensors; a processor with a memory coupled to receive inputs from the at least one sensor; at least one valve of a plurality of valves configured to be controlled by the processor, and coupled to a pressurized air supply; a buoyancy compensation bladder configured to receive air from the pressurized air supply as controlled by the valves; and a vent valve coupled to the control unit configured to release air from the buoyancy compensation bladder, the vent valve including:\n a valve plug configured to open or to close a valve seat, a spring configured to apply force to the valve plug to close the valve seat, a piston configured to apply force to the valve plug to open the valve seat, and a manual pull dump configured to open the valve seat manually, wherein the spring is fully restrained for more than 50% of its length, and the movement of the valve plug is constrained by a centering mechanism that prevents the valve plug from moving laterally or angularly while the centering mechanism allowing movement with the face of the valve plug parallel to the valve seat along the axis of a line extending perpendicular to the valve seat under any combination of over-pressure or manual pulling action using the manual pull dump, wherein the valve plug is configured to be biased to open the valve seat by a pneumatically or hydraulically powered means enabling powered actuation of the valve plug and/or by the manual pull dump enabling manual actuation of the valve plug and the valve plug is configured to be biased to close the valve seat by a counterforce created by or assisted by the spring, providing a first instantaneous flow rate from the powered actuation of the valve plug lower than a second instantaneous flow rate from the actuation of the valve plug through over-pressure relief or the manual actuation.
