Abstract:
A beverage dispensing valve, comprising:a valve body having a beverage inlet in fluid communication with a flow cavity within the valve body, a valve seat within the flow cavity in fluid communication with a port leading directly to a flow passageway, the flow passageway being generally conical in shape and increasing in diameter in a downstream direction from the seat to a distal end thereof and defining an internal conical flow passageway flow surface, a flow regulator having a conical end portion and an opposite nozzle end portion, the conical portion being retained within the flow passageway and leaving an external conical flow surface generally complimentary in shape to that of the internal conical flow passageway flow surface and the flow regulator positioned so that there exists a conical flow passageway between the internal conical flow surface of the flow passageway and the external conical flow surface of the flow regulator, and the flow regulator nozzle end extending externally of the flow passageway and having a central flow passageway in fluid communication with the conical flow passageway, sealing means for fluid tight sealing of the flow regulator conical portion within the flow passageway, an adjustment means including a ring threadably secured around a spout portion of the valve body out of which spout portion the nozzle end portion of the flow regulator extends, the ring cooperating with a flange of the nozzle end portion of the flow regulator for setting the position of the flow regulator for adjusting the amount of separation between the internal conical flow surface of the flow passageway and the external conical flow surface of the flow regulator for regulating the flow rate of beverage through the conical flow passageway so that said flow rate can be adjusted manually without contact with the beverage or with surfaces that come into contact with the beverage either during a dispensing of the beverage or between dispensings thereof, and a linear drive means for operating a closure member having a distal end extending into the flow cavity, the closure member distal end having a seal thereon for cooperating with the seat for regulating beverage flow from the flow cavity into the flow passageway.
