Abstract
A carbon dioxide manifold contains an internal passage providing communication between a pump supply, a liquid container, a gas container, and a beverage dispenser. A valve is located inside the internal passage. The valve has an open position in which communication exists between the liquid container, the gas container, and the beverage dispenser, but not with the pump supply. The valve has a closed position in which communication exists between the pump supply and the liquid container, and between the gas container and beverage dispenser, but the only communication between the pump supply/liquid container and the gas container/beverage dispenser is through an orifice that allows a restricted flow of carbon dioxide through the valve.
Claims10
A manifold for a carbon dioxide system comprising a pump supply, a liquid container, a gas container, and a beverage dispenser, the manifold comprising:
- (a) an internal passage providing communication between the pump supply, the liquid container, the gas container, and the beverage dispenser;
- and
- (b) a valve inside the internal passage having an open/operating position in which communication exists between the liquid container, the gas container, and the beverage dispenser, but not with the pump supply;
- and having a closed/refilling position in which communication exists between the pump supply and the liquid container, and between the gas container and beverage dispenser, but the only communication between the pump supply/liquid container and the gas container/beverage dispenser is through an orifice that allows a restricted flow of carbon dioxide through the valve.
A manifold for a carbon dioxide system comprising a pump supply, a liquid container, a gas container, and a beverage dispenser, the manifold comprising:
- (a) an internal passage means providing communication between the pump supply, the liquid container, the gas container, and the beverage dispenser;
- and
- (b) a valve means inside the internal passage means having an open/operating position in which communication exists between the liquid container, the gas container, and the beverage dispenser, but not with the pump supply;
- and having a closed/refilling position in which communication exists between the pump supply and the liquid container, and between the gas container and beverage dispenser, but the only communication between the pump supply/liquid container and the gas container/beverage dispenser is through an orifice that allows a restricted flow of carbon dioxide through the valve means.
A dispensing system for a fluid stored in liquid and gas phases, the system comprising a liquid pump supply, a liquid container, a gas container, a gas dispenser, and a manifold comprising:
- (a) an internal passage providing communication between the pump supply, the liquid container, the gas container, and the gas dispenser;
- and
- (b) a valve inside the internal passage having an open/operating position in which communication exists between the liquid container, the gas container, and the gas dispenser, but not with the pump supply;
- and having a closed/refilling position in which communication exists between the pump supply and the liquid container, and between the gas container and gas dispenser, but the only communication between the pump supply/liquid container and the gas container/gas dispenser is through an orifice that allows a restricted flow of carbon dioxide through the valve from the pump supply/liquid container to the gas container/gas dispenser.
