摘要： A beverage dispensing system has a valve in a tap controlling dispensing of the beverage through a first passage from a second rigid or flexible container. Air, nitrogen (or other inert gas) or carbon dioxide gas from a passage is introduced into the beverage in the first passage during dispensing for development of a head of froth. The introduced gas flows under pressure (which is preferably adjustable) from the second passage and by way of a capilliary tube restrictor and a non return valve communicating with the tube into the beverage in the first passage. The non return valve has a resilient diaphragm which normally closes that valve and is displaceable under gas pressure to admit the gas to the beverage. A labyrinthine mixer is located in the first passage downstream of the position where the gas is introduced.

摘要： A fluid pressure control valve and a fluid control system (such as for beverage dispensing) with such a valve has a beverage passage 3, pressure fluctuations in which are detected by a diaphragm 17 to displace a sensing member 15 axially against spring loading 23. Spring 23 reacts on thrust member 22 which is adjustable axially through a cam mechanism 25/26 to vary the biasing force of spring 23. A valve member 20 spring loaded at 21 relative to thrust member 15 normally closes an exhaust port 19 to an air or other gas passage 5 through which gas passes under pressure to be injected into the beverage from passage 3. An increase in beverage pressure in passage 3 displaces sensing member 15 to increase the spring biasing 21 on the closure member 20 and reduce the proportion of air which can escape to atmosphere from passage 5 through exhaust port 19 to provide an increase in air flow into the beverage. A reduction of pressure in passage 3 reduces the spring biasing 21 to permit a greater proportion of air to escape from passage 5 through exhaust port 9 and thereby reduce the proportion of air which is introduced into the beverage. The control valve can include a temperature sensitive unit responsive to temperature of beverage in passage 3 and which reacts to adjust the force of biasing spring 21 independently of pressure in the passage 3. Plunger 51 can be depressed manually to close the exhaust port 19 temporarily and thereby maintain maximum air pressure in the passage 5.

摘要： A beverage dispensing system and distributing process with such a system has a flexible bag 1 containing the beverage which may have carbon dioxide dissolved therein. The beverage is drawn off through a pipe 3 (assisted by a pump 8) for dispensing through nozzle 5 having a tap 6. Carbon dioxide, nitrogen (or other inert gas) and/or air gases are introduced into the beverage through a passage 11 by way of a fixed orifice restrictor 12 and a non-return valve 13. The pressure of the gas which is introduced is adjustable at 14 and baffles 15 can provide turbulence in the beverage during dispensing to promote the dissolution of the introduced gas therein.The facility to introduce the gas or gases permits the beverage in the bag 1 to have a low content of carbon dioxide so that the bag collapses under atmospheric pressure while the beverage as dispensed is additionally gasified for the formation of a froth or head.
摘要翻译：具有这种系统的饮料分配系统和分配过程具有容纳可溶解有二氧化碳的饮料的柔性袋1。饮料通过管3（由泵8辅助）排出，用于通过具有抽头6的喷嘴5分配。二氧化碳，氮气（或其它惰性气体）和/或空气通过通道11引入饮料中通过固定节流孔限制器12和止回阀13.导入的气体的压力可在14处调节，并且挡板15可以在分配期间在饮料中提供湍流以促进其中引入的气体的溶解。引入气体或气体的设施允许袋1中的饮料具有低的二氧化碳含量，使得袋在大气压力下塌陷，同时分配的饮料另外气化以形成泡沫或头部。
