Abstract
A fluid operated timer includes an input for the fluid, a reservoir receiving fluid from the input, an actuator responsive to the fluid pressure in the reservoir reaching a threshold value, wherein the reservoir includes a plurality of separate reservoirs. The timer further includes an element for selectively controlling operative connection of at least one of the plurality of separate reservoirs to the input so that the volume of the reservoir presented to the input fluid can be selectively varied.
