ABSTRACT:
A refill-prevention valve has a housing. The housing has a first tubular section defining a first passage, a second tubular section axially projecting from the first tubular section and defining a second passage being in fluid communication with the first passage, a third tubular section transversely projecting from the second tubular section and defining a third passage being in fluid communication with the second passage, and an annular flange which is formed on an internal surface of the housing between the first and second tubular sections and which defines an aperture. An annular plug is received in the aperture defined in the annular flange. A sleeve defines an aperture, an open end being disposed on the annular plug, a closed end and a disk formed on the closed end. A plunger is slidably received in the second passage for pushing the sleeve into the aperture defined in the annular flange and for pushing the annular plug out of the aperture defined in the annular flange.
