Abstract
A beverage dispensing valve includes a housing defining a chamber with an inlet for receiving a fluid and an outlet for dispensing the fluid. A piston is located in the chamber and subjected to a fluid pressure exerted by the fluid received via the inlet. The piston is moved axially in the chamber by the fluid pressure such that the piston determines a flow characteristic of the fluid dispensed via the outlet. A plunger is received in the chamber, and the fluid pressure tends to move the piston towards the plunger. A spring tends to move the piston away from the plunger, against the fluid pressure. The plunger is axially registered in the chamber in discrete plunger positions, and each plunger position sets a discrete limit on axial movement of the piston thereby determining a predetermined flow characteristic of the fluid dispensed via the outlet.
