The syruper has a rotatable bowl carrying filling syrup, with a number of filling valves arranged on the bowl bottom around its periphery to fill empty containers moved into travelling engagement with each valve. Each filling valve includes a ported valve seat mounted in an opening in the bowl bottom. A pivotable ported valve disc overlies the valve seat. A valve stem extending upwardly out of the bowl carries a crank mounted control cam follower and a switching cam follower. - A stationary control cam above the bowl, and in tracking engagement with the control cam follower for each filling valve, controls the location of the valve disc ports in relation to the valve seat ports to manipulate each valve in a repeating sequence through close, vacuum, fill and vent positions. The switching cam follower also tracking the control cam, and a cooperating switch, activate the valving sequence if a can is present at a particular filling valve and de-activate the sequence if a can is not present.
