Abstract
Abstract A valve assembly especially suitable for mounting in the bung opening in the side wall of a beer keg, and containing a skeletal tubular housing and a siphon tube which extends into said keg. A valve body is mounted in the tubular housing for movement between a closed position in which it is in closed, sealing engagement with the bung opening, and an open position in which it is spaced from the bung opening to permit cleaning liquid or beer to flow past the valve body and into the keg, said valve body being yieldably biased toward the closed position. Liquid and gas passageways with associated valve means are provided in the valve body, whereby gas under pressure can be admitted into the keg and beer can be withdrawn therefrom when the valve body is in the aforesaid closed position, as by using a tapper attachment.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
199 words
A valve assembly for mounting in an opening contained in the wall of a keg, comprising: a tubular valve housing having one end thereof adapted to be supported in said opening and including one internal shoulder adjacent said one end; a plurality of openings in said housing adjacent said shoulder to provide communication with the interior of the keg; a valve body having an end portion mounted in said housing for limited axial movement therein relative to said one internal shoulder, between a closed position in which said end portion is in sealing engagement with the shoulder and an open position in which it is spaced therefrom, the openings in the housing being unobstructed when said valve body is in the open position; a liquid passageway and a gas passageway in the valve body for communication with the interior of a keg, each of which passageways contains a valve seat; a valve element associated with each valve seat and yieldably biased toward said seat by an actuator; an elongated siphon tube having one end thereof interconnected with said valve body and in communication with the liquid passageway therein; and yieldable means biasing the valve body toward the closed position.
Claim 2
Dependent Claim
199 words
A valve assembly for mounting in an opening contained in the wall of a keg, comprising: a tubular valve housing having one end thereof adapted to be supported in said opening and including one internal shoulder adjacent said one end; a plurality of openings in said housing adjacent said shoulder to provide communication with the interior of the keg; a valve body having an end portion mounted in said housing for limited axial movement therein relative to said one internal shoulder, between a closed position in which said end portion is in sealing engagement with the shoulder and an open position in which it is spaced therefrom, the openings in the housing being unobstructed when said valve body is in the open position; a liquid passageway and a gas passageway in the valve body for communication with the interior of a keg, each of which passageways contains a valve seat; a valve element associated with each valve seat and yieldably biased toward said seat by an actuator; an elongated siphon tube having one end thereof interconnected with said valve body and in communication with the liquid passageway therein; and yieldable means biasing the valve body toward the closed position.
Claim 3
Dependent Claim
35 words
A valve assembly according to claim 1, in which each valve actuator comprises a permanent magnet of cylindrical shape positioned in a tubular housing which is intErconnected with the end portion of the valve body.
Claim 4
Dependent Claim
48 words
A valve assembly according to claim 2, in which the actuator associated with the gas passageway has a permanent covering of a material with a relatively low coefficient of friction, and the actuator is in sliding engagement with the inner surface of the tubular housing which receives it.
Claim 5
Dependent Claim
55 words
A valve assembly according to claim 1, in which the actuator for the liquid passageway valve element is positioned in a tubular housing which has one end thereof interconnected with the end portion of the valve body and the other end of said tubular housing is interconnected with said one end of the siphon tube.
Claim 6
Dependent Claim
77 words
A valve assembly according to claim 1 in which: the valve housing has another end opposite from said one end, which receives and supports said one end of the siphon tube; the actuator for the liquid passageway valve element is positioned in a tubular housing which has one end thereof connected to the end portion of the valve body; and a tubular connector extends between and is in communication with said tubular housing and the siphon tube.
Claim 7
Dependent Claim
28 words
A valve assembly according to claim 5 in which the tubular connector is removably connected to the tubular housing and is in telescoping engagement with the siphon tube.
Claim 8
Dependent Claim
65 words
A valve assembly according to claim 6 in which the tubular connector contains a flange member adjacent to the tubular housing to limit the movement of the connector relative thereto, and a coiled spring is positioned about the tubular connector with one end of the spring in engagement with the flange and the other end in engagement with said other end of the valve housing.
Claim 9
Dependent Claim
82 words
A valve assembly according to claim 1 in which: the end portion of the valve body is disc-like and contains a central liquid passageway and a plurality of gas passageways adjacent thereto, each of said passageways containing a valve seat; each of said valve actuators is a permanent magnet which is positioned in a tubular housing which has one end thereof connected to said end portion in communication with one of said passageways; and permanent magnets are mounted between said tubular housings.
Claim 10
Dependent Claim
52 words
A valve assembly according to claim 8 in which each of the tubular housings in communication with a gas passageway contains an opening in the wall thereof adjacent to the valve seat, which opening is unobstructed when the valve element associated with said valve seat is spaced therefrom in an open position.
Claim 11
Dependent Claim
63 words
A valve assembly according to claim 1, which further includes: a flange portion adjacent said one end of the valve housing for engagement with the outer wall surface of the keg adjacent said opening; and an annular resilient member positioned about the valve body and spaced from said flange portion, for engagement with the inner wall surface of the keg adjacent said opening.
Claim 12
Dependent Claim
36 words
A valve assembly according to claim 1, which further includes: another internal shoulder in the tubular valve housing, spaced from said one shoulder, limiting the movement of the valve body away from said one internal shoulder.
Claim 13
Dependent Claim
54 words
A valve assembly according to claim 11, which further includes: an annular resilient member mounted on said valve body for sealing engagement with the one internal shoulder when the valve body is in the closed position, and for sealing engagement with said other internal shoulder when the valve body is in the open position.
