Abstract
An in line mechanical timing valve is disclosed. The valve has an inlet capable of being coupled to a water source and an outlet. A valve housing is fluidly coupled to the inlet and the outlet to control water flow between the inlet and the outlet. A bisecting cylinder is installed perpendicular to the inlet and outlet. The bisecting cylinder has a central axis and a diaphragm which has an open position allowing water flow to the outlet and a closed position preventing water flow to the outlet. A dial knob has an extended position and a retracted position. The dial knob is rotatable about the central axis of the bisecting cylinder when in the retracted position. A timing mechanism has a windup shaft parallel to the central axis of the bisecting cylinder. One end of the windup shaft has one end coupled to the dial knob which allows the timing mechanism to be set by the dial knob. A shaft parallel to the central axis of the bisecting cylinder is inserted through the timing mechanism. The shaft has a first end which is coupled to the diaphragm and an opposite second end which is coupled to the dial knob. The dial knob may be rotated to set the timing mechanism to remain in an extended…
