ABSTRACT:
A pressure control system for a storage tank, including a supply of working fluid under pressure. A conduit establishes fluid communication between the supply and the storage tank. A supply regulator is provided in the conduit for maintaining a substantially constant pressure to the storage tank. A tank regulator is provided in the conduit between the supply regulator and the storage tank for selectively admitting the substantially constant pressure as a function of temperature to the storage tank. A control selectively operates the tank regulator in response to given conditions, such as temperature conditions, in the storage tank.
