  • Patent number: 8834069
    Abstract: A buoyancy compensation apparatus for underwater use by a SCUBA diver, includes a pressurized air source, a buoyancy vest including air chambers and a pressure regulating unit. The pressure regulating unit includes a chamber in communication with the vest air chambers and the pressurized air source. The pressure regulating unit also includes a normally closed air injection valve and a normally closed relief valve. The wall of the pressure regulating unit chamber includes a flexible portion that flexes inwardly when outside water pressure exceeds the pressure in the vest air chambers, which, in turn, opens the air injection valve. The relief valve opens when air pressure in the vest air chambers exceeds outside water pressure. The air injection and relief valves respond faster than the walls of the buoyancy vest air chambers so that the volume of the vest air chambers remain generally constant even as the diver changes depth.

    Abstract: A gas regulator includes an actuator, a valve, and a cartridge disposed within the valve to advantageously direct, or “boost,” fluid downstream and away from the actuator under normal operating conditions, thereby increasing the operating efficiency of the regulator. The cartridge includes a first portion with a first diameter and a second portion with a second diameter that is greater than the first diameter. During normal operation, the first portion receives a valve disc of the actuator within generally tight tolerances such that the valve disc and the cartridge restrict fluid communication between the valve and the actuator. This directs or “boosts” the gas toward the outlet of the valve. Additionally, during a relief operation, the second portion of the cartridge receives the valve disc to allow the free flow of gas to the actuator.

    Abstract: A gas regulator includes an actuator, a regulator valve, and pressure loading device. The pressure loading device provides a pressure load to a surface of a diaphragm of the actuator to act against a downstream pressure being applied to the opposite surface of the diaphragm and being controlled by the regulator. As the downstream pressure varies and the diaphragm displaces to move a control element to regulate the downstream pressure, the pressure loading device maintains a specified load pressure. The regulator may further include a balanced trim applying a balancing force to offset a force of an upstream pressure on the control element.

  • Patent number: 7500618
    Abstract: A valve device has a pressure chamber, which is connected to a liquid inlet and a liquid outlet and retains liquid, and a pressure regulator decreasing the pressure in the pressure chamber to a predetermined level. The pressure regulator has a pressure receiving member. When the pressure in the pressure chamber becomes lower than the predetermined level, the pressure receiving member is elastically deformed in an inward direction of the pressure chamber. The pressure regulator generates actuation force greater than the pressing force produced by the elastic deformation of the pressure receiving member. The pressure regulator is configured to be opened by the actuation force. When the pressure regulator is open, a fluid supply from the liquid inlet to the pressure chamber is permitted. It is thus possible to minimize the valve device.
