Abstract: A vapor compression refrigeration system having a condenser, a regulating device, and a capillary tube. The regulating device has a housing defining an inner chamber for receiving refrigerant from the condenser. A float is disposed within the chamber and may include a resilient surface. A spring is positioned between the float and a wall of the chamber. The spring facilitates the float in floating when the system is subject to a high differential pressure. A method of offsetting differential pressure in a refrigeration system is also described.
