ABSTRACT:
A fluid-operated dispensing device 10 includes a vessel 12 for defining a chamber 14 in which fluid is received. The vessel 12 also defines an inlet 18, a first outlet 24 and a second outlet 26. The inlet 18 has a greater cross sectional area than that of the second outlet 26. A first closure 28 is operatively arranged with respect to the inlet 18. The first closure 28 moves into an open position when pressure at the inlet 18 is greater than pressure within the chamber 14. The first closure 28 moves into a closed position when pressure within the chamber 14 is at least equal to pressure at the inlet 18. A second closure 50 is operatively arranged with respect to the second outlet 26. The second closure 50 moves into an open position when pressure within the chamber 14 is greater than pressure at the inlet 18. The second closure 50 moves into a closed position when pressure at the inlet 18 is at least equal to pressure within the chamber 14.
