Abstract
A dispenser for delivering beverages (e.g. beer) including a main body (20), an inlet (21), an outlet (23) and a piston stop valve (23). In use, the piston moves from a first closed position (A) to a second position (B) where fluid is permitted only through restrictive channels (30) that causes turbulent flow and hence foam formation for the head of the beverage. In a third position (C), flow is completely open from the inlet to the outlet and foam formation is minimised.

A dispenser including a main body with an inlet, an outlet and a piston, therebeing channels formed in the main body or the piston upstream of a sealing means associated with the piston adjacent the outlet.
