ABSTRACT:
A valve arrangement for a liquid flavoring additive under pressure, particularly a non-homogeneous liquid such as high pulp orange juice concentrate, utilizes a fluid pressure to assist in terminating discharge of the liquid flavoring. The fluid pressure may be achieved by utilizing the same compressed air utilized to force the liquid flavoring through the valve structure. Suitable controls, such as a three-way valve, may be utilized to apply the pressurized air to a diaphragm on which a valve member is carried when the valve is to be closed to preclude discharge of the liquid flavoring additive, and to remove the pressure on the diaphragm, such as by venting it to air, when it is desired to permit discharge of the liquid flavoring.
