Abstract
The invention is directed to a method for inflating a bladder including a first and a second distinct chamber linked in fluid communication by an interconnecting port, and a fluid fill inlet linked in fluid communication with the first chamber. A first nozzle set at a first predetermined pressure level and connected to a first fluid pressure source is inserted in the fill inlet to thereby inflate the first and second chambers to the first predetermined pressure. The interconnecting port is sealed to isolate the first chamber from the second chamber out of fluid communication with each other such that the second chamber is isolated at the first predetermined pressure. The first nozzle is removed from the fluid fill inlet. A second nozzle set at a second predetermined pressure level and connected to a second pressure source is inserted into the fluid fill inlet to thereby inflate the first chamber to the second predetermined pressure. The fluid fill inlet is sealed, to isolate the first chamber at the second predetermined pressure, and the second nozzle is removed from the fluid fill inlet.
