Abstract
A multiple action forced fluid evacuation system includes a reservoir for receiving a working fluid therein, and a shutoff valve provided in the reservoir. An outer rigid conduit and an inner flexible conduit are connected between the shutoff valve and a receiver. A processing module is provided for at least controlling pressurized gas between the outer conduit and the inner conduit, and is operatively connected to the outer conduit and the inner conduit. A nozzle has one end in fluid communication with a source of the working fluid, and an opposite end removably coupled to the receiver. The nozzle normally enables flow of the working fluid through the inner 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 leaving a portion of the working fluid trapped in the receiver and the inner conduit. 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.
