Patent number: 10639656Abstract: A crossover prevention valve for use in a multi-component fluid mixing and dispensing system includes a valve body defining at least two fluid passageways having respective one-way check valves at their outlet ends. A forward end of the valve body cooperates with an interior surface of a dispensing nozzle to define a mixing chamber for chemically reactive fluids prior to discharging the mixed fluids out of the dispensing nozzle. The crossover prevention valve does not permit reverse flow, thereby preventing clogs due to undesired intrusion of one reactant into the flow path of another reactant. Solidified reactants left in the mixing chamber are easily removed from the valve body, permitting the valve body to be reused even after sitting for extended periods.Type: GrantFiled: October 14, 2016Date of Patent: May 5, 2020Inventor: Gary M.
