摘要： In one form hereof, there is disclosed a keg adapter having a siphon body formed of bar stock receivable through the opening of a keg from without the keg. The siphon body has liquid and gas passages extending longitudinally of the keg adapter terminating at their upper ends in a pair of bores disposed eccentrically of the central axis of the keg adapter. In another form, there is disclosed a keg adapter having a siphon body formed primarily of tubular stock with tubular members receivable through the opening of a keg from without the keg. The tubular members per se comprise liquid and gas passages terminating at their upper ends in a pair of openings disposed eccentrically of the central axis of the keg adapter and opening through a flange member formed of bar stock. A coupler unit, having a pair of depending probes, is engageable with either form of the keg adapter with the probes being receivable in the bore holes or tubes as applicable to form a continuation of the liquid and gas passages. A sleeve is provided in the liquid passage of both adapters for opening a normally closed liquid valve therein. A gas valve is axially spaced from the liquid valve and in both forms includes a gas check valve comprising a flexible envelope having a slit and which envelope lies in communication with the gas passage. In the one form, the gas valve also includes a spring-biased valve plate mounting an O-ring sealing about the walls of the gas passage. The tips of the probes on the coupler unit in the one form depress the associated valve members to open the valves and permit ingress of gas through the coupler unit and keg adapter into the keg and egress of liquid from the keg through the keg adapter and coupler unit. In the other form, the tip of the liquid probe on the coupler depresses the sleeve to open the liquid valve whereby air flows through the coupler into the keg past the check valve of the adapter and beer flows outwardly from the keg through the adapter and coupler.

摘要： This invention relates to a beer tapping device and especially to an improved adapter for attachment in the beer outlet of a standard keg. It comprises a metallically enclosed, readily assembled unit, insertable from outside the keg with a laterally offset liquid passageway through the adapter. The offset passage takes optimum advantage of the limited space available while, at the same time, the unit is compatible with existing systems. Also disclosed is a novel metallic locking unit for separating the beer and gas passageways in the adapter as well as a novel flexible resilient check valve for the gas passage through the adapter.

摘要： The device includes a keg adapter mounted within a 1 1/2 inch keg opening and a dispenser coupler secured to the keg adapter, the adapter and coupler having gas and liquid passages for permitting ingress of gas into the keg and outflow of beer from the keg. The gas passage receives gas from a hand operated portable plunger type pump with the beer dispensing outlet including a spout. The coupler is secured to the adapter by rotating the former relative to the latter which, in turn, opens normally closed gas and liquid valves in the adapter. A liquid valve is disposed in the coupler and displacement of the spout opens the valve to permit outflow of beer therefrom.

摘要： The safety device is disposable in the gas line connecting between a gas source under pressure and a tapping device installed in a keg. The safety device includes a valve housing carrying a spring biased axially movable piston including a stem and an axially adjustable element on the upstream side of the stem, the element and piston having axial passages. On the downstream side of the piston, a slit valve is provided. In use, gas flowing into the valve through the passages in the element and piston flows into the keg through the slit valve. Upon an increase in gas line pressure above a predetermined pressure, the gas acts on the piston to displace it in an upstream direction against the bias of the spring to seal the stem against the element and preclude further ingress of gas into the keg. When keg pressure is relived as by drawing beer from the keg, the spring returns the piston to open the gas passage through the valve at the predetermined pressure. The gas check valve precludes backflow of liquid and gas through the gas passage.
摘要翻译：该安全装置在连接在压力下的气体源和安装在小桶中的攻丝装置之间的气体管线中是一次性的。安全装置包括承载弹簧偏置的可轴向移动的活塞的阀壳体，该活塞在杆的上游侧包括杆和可轴向调节的元件，元件和活塞具有轴向通道。在活塞的下游侧设置有狭缝阀。在使用中，通过元件和活塞中的通道流入阀的气体通过狭缝阀流入小桶。当气体管线压力增加到高于预定压力时，气体作用在活塞上以抵抗弹簧的偏压在上游方向上移动，以将阀杆抵靠元件密封，并排除气体进入小桶的进一步进入。当小桶压力通过从小桶中抽出啤酒而恢复时，弹簧返回活塞以在预定压力下打开通过阀的气体通道。气体止回阀排除液体和气体通过气体通道的回流。

摘要： The tapping device includes a keg adapter semi-permanently secured within a keg opening and having liquid and gas passages. The keg adapter is secured by an externally threaded ring which locks under the keg flange by cooperation with a collar which locks the keg adapter flange to the keg flange. A coupler having segregated liquid and gas passages and an internally threaded collar is attached to the keg adapter when the keg is tapped with the collar being threadedly secured to the ring.
