Abstract:
A reflux valve engageable with corresponding structure, said reflux valve comprising: a valve body; an actuator at least partially disposed in said valve body; a valve stem in said valve body, said valve stem biased into a valve seat in said valve body, said actuator shiftable relativc to said valve body upon the corresponding structure being engaged with said actuator, wherein said actuator pushes said valve stem out of engagement with said valve seat in said valve body, whereafter liquid is flowable, in one direction, through the actuator, past said valve seat, along an area adjacent a periphery of the valve stem, and out said valve body, and in an opposite direction, along said area adjacent said periphery of said valve stem, past said valve seat, through said actuator, and out said valve body; a first retainer disposed on said actuator and configured to engage the corresponding structure upon the corresponding structure being engaged with said actuator; and a second retainer disposed on said actuator and engaged with an internal wall of said valve body, said valve stem including an integral frusto-conical portion which engages said valve seat to prevent liquid from flowing therepast, said actuator including a notch proximate said valve stem, said notch configured to facilitate the flowing of liquid between said actuator and said valve stem.
