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.

Flow control valves for post-mix beverage dispensers

A beverage dispenser of the type having a diluent mixed with a syrup to produce the beverage to be dispensed is provided with a solenoid actuated valve arrangement between the diluent and/or syrup supply line and the dispensing nozzle and which solenoid valve has a sealing arrangement which, upon actuation of the solenoid, provides sequential first and second stages of pressure drop across the valve seat, thus to reduce the power required to operate the solenoid and open the valve or enable the valve to operate under higher fluid pressures without increasing the power of the solenoid.
