Volume control for multi-nozzle rotary pump filling systems

A volume control for multi-nozzle rotary pump filling systems in which several containers are to be filled simultaneously with the same amount of fluid product, comprising a plurality of rotary pump means, each having an in-feed side and a discharge side, a plurality of nozzle means, common drive means for said rotary pump means including monitoring means for monitoring at least the number of revolutions made by the pump means and operable to control the common drive means in such a manner that said pump means deliver the fluid product to said nozzle means at the same time, and connecting means operatively connecting a respective pump means with a corresponding nozzle means to provide a multi-nozzle filling system, said connecting means including, in each operative connection between a respective pump means and the corresponding nozzle means of the multi-nozzle filling system control means in each such operative connection for individually controlling the amount of product dispensed by a corresponding nozzle means by adjustably varying the back pressure on the respective pump means operatively connected therewith, and said control means including adjustable restricted passage means in the connection means between a respective pump means and the corresponding nozzle means to enable fine adjustment of the amount of fluid product delivered by a given nozzle means.
