A beverage dispense apparatus having one or more outlets for fluids to be dispensed, a fluid supply line for each fluid, each outlet being governed by a valve, and a valve actuator to open and close each valve. A flow sensor is positioned in each fluid supply line and connected to a control which controls the opening of its respective valve on receiving a start signal and actuates closing of the valve when the pre-determined amount of fluid flow has been achieved. Each valve includes a closure member movable in a passageway from a first position in which the valve is fully closed to a second position in which the valve is fully open. The closure member comprises a groove having a transverse cross section that increases in area in the downstream or upstream direction, whereby movement of the closure member from the first position towards the second position opens a flow channel through the groove.
A beverage dispense apparatus comprising a dispense head (10, 20) having one or more outlets (11) for fluids to be dispensed, a fluid supply line (16, 17) to the head (10, 20) for each fluid, each outlet (11) being governed by a valve, and a valve actuation means (13, 14, 25, 26) to open and close each valve, characterised in that a flow sensor (18, 19, 32) is positioned in each fluid supply line and connected to a control means (15) which controls the valve actuation means whereby it actuates opening of its respective valve on receiving a start signal and actuates closing of the valve when the pre-determined amount of fluid flow has been achieved, and in that the valve (110) of each outlet comprising a housing containing a passageway (112, 131, 141, 151, 161) between an inlet (113, 132, 142, 152, 162) and an outlet (114, 133, 143, 153, 163)of the valve, a closure member (111, 130, 140, 150, 160) movable in 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 closure member (113, 130, 140, 150, 160) engaging the wall of the passageway (112, 131, 141, 151, 161) to seal the passageway, the wall of the passageway and/or the closure member defining at least one groove (116, 117;
An apparatus according to any preceding claim, which includes a temperature sensor.
An apparatus according to any preceding claim, characterised in that the closure member (111, 130) carries a sealing ring (119, 135) to engage the wall of the passageway (112, 131).
An apparatus according to any preceding claim, characterised in that the passageway (112, 131, 141, 151, 161) and closure member (111, 131, 141, 151, 161) are of generally cylindrical transverse cross-section and a pair of grooves (116, 117;
An apparatus according to any preceding claim, characterised in that the outlet (114) from the passageway (112) extends at right angles to the passageway, a pair of diametrically-opposed grooves (116, 117) of V-shaped cross-section is positioned in the wall of the passageway adjacent the inlet (113) and the grooves increase in area in the downstream direction, the passageway tapers so as to narrow upstream of the inlet (113), and an O-ring (119) on the closure member (111) seals against the tapered wall (123) of the passageway to close the valve.
An apparatus according to any preceding claim, characterised in that the grooves are V-grooves, each groove widening along its length at an angle of from 1° to 20°.
An apparatus according to any preceding claim, characterised in that more than one groove is positioned in the passageway, and at least one groove starts and/or finishes at a different position along the passageway to another groove.
