  • Portable sprayer with connector mounting beams
    Patent number: 7478766
    Abstract: A portable, battery-powered sprayer for dispensing two liquid products at the same time. A reservoir cartridge having two liquid chambers is removably installable in a reciprocating bay in the housing. First and second mating pairs of fluid connectors each have a component mounted on the cartridge and a component mounted in the housing. A cam on a pivotable lever causes the bay to move the fluid connector components into and out of engagement. The fluid connector components permit fluid flow when they are joined and prevent it when they are separated. A support beam locks the housing components of the fluid connectors in fixed relation to one another. A guide strip locks the cartridge components in the same fixed relation to one another. A docking station in the bay locates the guide strip.
