Abstract

A drive system for side-by-side piston pumps connected to beverage concentrate containers in a post-mix beverage dispenser system is described. An electric motor rotates a drive shaft in either a forward or reverse direction for the selective actuation of one or the other of the piston pumps. First and second hollow shafts are concentrically disposed around the drive shaft, one hollow shaft being mechanically coupled through a cam and lever arrangement to each of the piston pumps. Free-wheeling clutches are provided between the drive shaft and each of the respective hollow shafts such that one hollow shaft is coupled to rotate with the drive shaft in the forward direction of rotation of the drive shaft and the other hollow shaft is coupled to rotate with the drive shaft in the reverse direction of rotation of the drive shaft.
