A dispensing valve is shown that controls the flow of a fluid, the valve having a housing containing a cylindrical/tubular passageway between an inlet and outlet of the valve. A rod like closure member is operable to move through the passageway from a first position in which the valve is fully closed, to a second position in which the valve is fully open. The exterior surface of the closure member engages the interior surface wall of the passageway to seal the passageway and the interior surface wall and/or the exterior surface of the closure member have helical/spiral grooves therein. A spiral flow passage is defined through which the fluid can flow on its passage from the inlet to the outlet when the closure member moves away from its first position. Further movement of the closure member towards the second position regulates the flow rate of the fluid through the passageway.

Dispensing valve with helical flow orifice

A settable control valve ( ) has a closure member moveable within a passage-way ( A, ), there being at least one groove for fluid flow ( ) in the wall of the passageway. The groove is of varying transverse cross-sectional area along its length and the closure member may be set at different positions so as to expose varying lengths of the groove to fluid flow, hence enabling different fluid flow rates to be established.

Valve

Cooler for a beverage, e.g. beer, which enables dispense at low temperature with good appearance of the dispensed beverage, comprises an inlet and an outlet, at least one heat exchanger ( ) between the inlet and the outlet through which the beverage can be passed to cool it and at least one Peltier plate assembly ( ) connected to a voltage supply whereby a cold side and a hot side may be generated at the assembly, characterised in that the assembly ( ) is positioned whereby the beverage can also be cooled by passage past the cold side of the assembly ( ) on its passage to the outlet or whereby the coolant after passage through the heat exchanger ( ) is cooled by passage past the cold side of the assembly ( ) before being recirculated to the heat exchanger ( ).
