ABSTRACT:
A fluid circulating system including a pump and an accumulator-reservoir device of the bootstrap type in which operation of the pump energizes the device to maintain a pressurized system despite an increasing fluid density caused by lowering fluid temperatures. A light spring force is applied which establishes a minimal system pressure effective even when the pump is shut off and which maintains in its proper convolution a rolling diaphragm comprised in the accumulator-reservoir device.
