US 7,252,113 B2 · Mechanical in line timer valve

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 position for a set period of time.

Dependent claims

A timer valve for controlling the flow of water, the valve comprising:

a main body having an inlet and outlet for communication of water through the valve;
a valve between the inlet and outlet, the valve having a plunger shaft therethrough which activates the valve;
a timing mechanism controlling the plunger shaft, the timing mechanism having gearing and a windup shaft which turns the gearing, the windup shaft extending parallel to the plunger shaft;
a first coil spring coupled to the windup shaft, the coil spring being wound up by rotating the windup shaft;
and
wherein the gearing provides resistance against the first coil spring such that when the first coil spring is wound up, it is released slowly to rotate the windup shaft;
and
a control mechanism which is coupled to the windup shaft and allows the timing mechanism to be set to move the plunger shaft to activate the valve for a predetermined amount of time.
