20110073617 | LOCKING ACCESS PLUG FOR A BAR GUN - A locking access plug for a valve return spring for a beverage dispensing gun handle is disclosed. The locking access plug enables the compression and retention of the valve return spring and enables the retention of the locking access plug in the body of the handle until it is acted upon for the purpose of its removal; for example, for the servicing of the handle. A beverage dispensing gun having such a locking access plug can both keep a valve return spring in compression as well as interface with a sealing o-ring that seals between the locking access plug and the beverage dispensing gun handle. | 03-31-2011 |
