ABSTRACT:
A pressure gas ventilated pressure suit comprises a suit adapted to cover a person which includes a head portion with a face encompassing part which defines a breathing space in front of the person's face and which also includes a body portion defining a pressure space around the person's body and parts of the person's head which is separate from the breathing space. A connection is established between the breathing space and the pressure space through a check valve which permits inhaling of the air found in the pressure space through the breathing space to the wearer. The pressurized breathing gas is connected to discharge gas into the pressure space to maintain it at a predetermined pressure which advantageously provides an inflation of the body portion of the suit. During breathing the wearer inhales in the breathing space and pulls in some of the air from the pressure space through the check valve. The air is exhaled through an exhaling valve connected into the breathing space. The suit advantageously provides a device for adjusting the pressure in the body portion through the regulation of a pressure regulating valve which is connected to the discharge of a compressed air tank.
