ABSTRACT:
Adjustable flow control valves are disclosed for controlling the flow of syrups and diluents at a corresponding predetermined constant flow rate regardless of the pressure of the fluid being controlled. The valves include a cylinder and piston assembly in which the piston has an inlet orifice and controls outlet ports from the cylinder to maintain a constant flow rate. Dual spring arrangements provide for adjusting the range of flow rates which the valve can accommodate in connection with varying pressure and varying viscosity of the liquid being controlled, and variable piston orifice arrangements are disclosed for the same purpose. An improved cylinder construction comprising sleeve and bonnet components is disclosed and provides for the outlet ports from the cylinder to be provided in the bonnet component.
