ABSTRACT:
A container filling machine for filling beverages into containers has a filler valve configured for allowing the valve to operated by a simplified control system. The valve has a valve body and a gas pipe disposed concentrically therewith, wherein there is a first spring for applying a biasing force between the gas pipe and the valve body to bias the valve body to its closed position, and a second spring, which when compressed by a control cam when there is a container present provides a force sufficient to overcome the biasing force of the first spring and thereby open the valve. In the absence of a container, the control cam for opening the valve body is able to run through its normal operation cycle without causing the valve to be opened because the gas pipe is configured to hold the valve body closed under a force applied by pressurized gas in the filling machine.
