Abstract: An apparatus and method is provided for automatically venting a fluid from at least a portion of a pressurized system. An interconnection between two devices in the system contains an automatic bleed valve configured to automatically seal a vent hole when the two devices are coupled together and to automatically unseal the vent hole before the two devices are separated. In an embodiment, an adapter includes a ring that both screws a connector onto a device and seals a vent hole. A pin is pushed into the vent hole as the connector is screwed to the device. To remove the adapter from the device, the ring is turned to both unseal the vent hole and to unscrew the connector from the device. Turning the ring releases the pin before the connector is unscrewed.
Abstract: A short, compact pressure cylinder filled with compressed air under about 3000 psi operating pressure is provided with a scuba type breathing regulator attached to the top thereof. A quick release holster surrounds the cylinder and is easily attached to any flight suit or vest which may be worn by a user. Attached to the holster is a mouthpiece cover to keep the mouth piece and the breathing chamber of the regulator clean and free of debris. The apparatus is easily operated and automatically activated simply by pulling the cylinder from the holster in a single movement. This removal of the cylinder from the holster acts to simultaneously remove the mouthpiece cover and open a supply valve in the regulator, permitting air to be supplied to the regulator valve. The apparatus is sealed at the place of manufacturing and is designed to be virtually maintenance free.
