Abstract
An intermittent fluid flow controller including a main body that houses an inlet in controlled fluid communication with an outlet, a mechanical timing mechanism including a rotatable member that rotates during an operation of the timing mechanism, and a first valve operated by the rotatable member. The first valve is disposed in the main body such that a rotational movement of the rotatable member actuates the first valve to intermittently permit and restrict a fluid flow between the inlet and the outlet over a pre-selected period of time determined by the operation of the timing mechanism.
