Abstract
The present invention generally relates to an apparatus and method for urging fluid from a charging system to a pressurized system. The apparatus has a rigid body with a conduit defined therein. The body is mounted between, and connected to, a charging system containing pressurized fluid and a pressurized system. More specifically, a retractable discharge tube for actuating a first valve to allow the release of fluid held within the charging system, is inserted into a first end of the body. A depressor mounted at a second end of the body is inserted into a tubular fitting connected to the pressurized system. The fitting has a retractable pin for actuating a second valve to permit entry of the fluid into the pressurized system. Once the body is connected to both the charging system and the pressurized system, a force is applied on the charging system toward the pressurized system. The force causes the charging system and the pressurized system to mate with the body. The mating of the body structure to the charging system and the pressurized system urges the discharge tube to retract, thereby actuating the first valve to release fluid into the conduit, and urges the pin to retract, t…
