Abstract
A storage tank comprising a container having an interior space and a pressure responsive wall defining a fluid storage chamber. The pressure responsive wall is displaceable as fluid is supplied to the storage chamber to increase the volume of the storage chamber. The storage tank also includes a variable volume chamber and movement of the pressure responsive wall to increase the volume of the storage chamber reduces the volume of the variable volume container. A compressible medium under pressure is provided in the variable volume container and the change in volume of the fluid storage chamber for a given displacement of the pressure responsive wall is greater than the change in volume of the variable volume container.
