Abstract:
1. A valve device for a beverage dispenser comprising: a tubular body having an upstream inlet end, a downstream outlet end, and an internal cavity having a first annular wall with a first radius, a second annular wall with a second radius larger than the first radius, and a shoulder transitioning between the first annular wall and the second annular wall; and a one-directional valve inside the tubular body, the valve comprising a pointed portion that points towards the upstream inlet end and wherein the pointed portion is biased to remain closed, wherein the downstream outlet end of the tubular body is configured to attach onto a downstream conduit and further wherein the pointed portion of the valve comprises multiple lips biased to remain closed and adapted to be forced open by the downstream conduit inserted through the downstream outlet end to allow for the flow of a fluid from the upstream inlet end and to the downstream outlet end and further wherein the downstream outlet end of the tubular body includes a radially inwardly extending annular ring fixed stationary to the second annular wall and with respect to the tubular body, the downstream conduit being adapted to sealingly engage when inserted into the downstream outlet end of the tubular body; and a retainer that rests against the annular ring and that retains the valve inside the tubular body of the device.
