ABSTRACT:
An accumulator tank for pressurizing and supplying liquid to a system comprises a pressure vessel having a wall defining a closed pressure chamber. The pressure vessel is provided with an internal flexible air cell which divides the pressure chamber into first and second variable volume compartments containing pressurized air and water, respectively. Perforated conduits are provided in the second compartment in fluid communication with a port, and extend between the wall of the pressure vessel and the flexible air cell. The perforated conduits provide fluid communication between the port and portions of the second compartment when the air cell seals against the wall to otherwise isolate those portions of the second compartment in fluid communication with the perforated conduits.
