Title: Apparatus and methods for testing, filling and purging closed fluid systems

Abstract

This patent describes an evacuation unit for testing the fluid tightness of a closed fluid system having an access port and for filing the system with fluid through the access port. It comprises: a first reservoir containing a first fluid; a second reservoir containing a second fluid; sequence valve means disposed between and communicating with the first and second reservoirs for selective positioning between a first position communicating the first reservoir with an outlet and a second position communicating the second reservoir with the outlet; vacuum pump means for producing a vacuum of a predetermined pressure less than atmospheric pressure, the vacuum pump means includes a source of air under pressure, a venturi, and conduit means interconnecting the pressurized air source and the venturi; connection means for releasable and sealable connection to an access port of a closed fluid system, the connection means includes a flexible hose having opposite ends, a filler head on one end of the hose for attachment to the access port, and coupling means on the other end of the hose; control valve means and; a separation tank.
