Patent ID: 7124914

Claim:
A dual liquid dispenser comprising: a first pump chamber; a second pump chamber; a first piston mounted in the first pump chamber for reciprocating movement of the first piston in the first pump chamber; a second piston mounted in the second pump chamber for reciprocating movement of the second piston in the second pump chamber; a first piston rod with a first rod passage extending through the first piston rod, the first piston being on the first piston rod; a second piston rod with a second rod passage extending through the second piston rod, the second piston being on the second piston rod; a manifold interconnecting the first piston rod and the second piston rod as one monolithic piece; the manifold having a bottom wall that interconnects the first piston rod and the second piston rod, the first and second piston rods opening through the manifold bottom wall communicating the first and second rod passages with an interior volume of the manifold; and, the manifold having a side wall that extends upwardly from and around the manifold bottom wall.
