Abstract
A beverage dispenser with a variable pressure regulator cap assembly that includes a high pressure cavity defined by a cap body. The high pressure cavity receives pressurized gas from a compressed gas reservoir. A low pressure cavity is connected to the high pressure cavity via a high pressure gas passageway. The low pressure cavity defines a low pressure gas passageway that penetrates the cap body. A piston seat is positioned on a high pressure cavity side of the high pressure gas passageway. A piston regulates introduction of the pressurized gas into the high pressure gas passageway. A diaphragm is positioned between an ambient pressure cavity and the low pressure cavity and translates the piston relative to the piston seat. A main spring is positioned between a diaphragm and a spring hat. Rotation of the drive screw translates the spring hat to affect compression of the main spring against the diaphragm.
