Multiple action forced fluid evacuation system

A method of controlling and evacuating fluid between different locations comprising the steps of:

• a) providing a reservoir for receiving a working fluid therein from a supply source;
• b) providing a shutoff valve in the reservoir;
• c) providing an outer rigid conduit having one end connected to the receiver, the outer rigid conduit being in fluid communication with a fluid source supplying pressurized gas;
• d) providing an inner flexible conduit for conducting the working fluid therethrough, the inner flexible conduit having one end in fluid communication with the reservoir, and an opposite end connected to and in fluid communication with the receiver, the inner flexible conduit being disposed within the outer rigid conduit and being subjected to the pressurized gas in surrounding relationship therewith;
• e) providing a processing module for at least controlling the pressurized gas to the outer rigid conduit, the processing module being operatively connected to the outer rigid conduit and the inner flexible conduit, and
• f) providing a nozzle having one end in fluid communication with the supply source of the working fluid, and an opposite end removably coupled to and in fluid communication with the receiver, the nozzle being configured to transmit signals to the processing module, and to be responsive to an actuation of the shutoff valve,
• wherein the nozzle normally enables flow of the working fluid through the inner flexible conduit to the reservoir when the nozzle is connected to the receiver until the working fluid in the reservoir activates the shutoff valve causing the nozzle to cease flow of the working fluid from the supply source thereof leaving a portion of the working fluid trapped in the receiver and the inner flexible conduit, and wherein removal of the nozzle from the receiver activates the processing module and causes the portion of the working fluid trapped in the inner conduit and the receiver to be completely and sequentially evacuated into the reservoir.
