Claim 2:
3. A control valve system for a water sprinkler, said control valve system being contained in a single, discrete housing, and said control valve system further comprising:
a water inlet that accepts water piped into it from a water source, and a water outlet that directs water towards the water sprinkler when the control valve system is open; a programmable clock apparatus comprising a mechanical clock mechanism and a mechanical mainspring, the programmable clock apparatus capable of opening and closing the control valve system by using a first connecting apparatus;
the first connecting apparatus functions to convert the rotational movement of an hour dial and a minute dial to a linear movement of a valve plug component to open and close the valve system and control the flow of media through it;
a turbine apparatus comprising a turbine shaft that has a turbine impeller on one end that is capable of turning when water flows through the control valve system, wherein when the turbine impeller turns its rotational energy is transferred to the mechanical mainspring of the programmable clock apparatus; and
wherein the first connecting apparatus comprises a lever mechanism, the lever mechanism comprising a first arm and a second arm, the first arm being connected to the valve plug component and the second arm being connected to the hour dial and the minute dial, the first arm and the second arm being joined together with a spring hinge so that the angle between the first arm and the second arm can be adjusted by a force applied to the lever mechanism, wherein when the hour dial is set to a particular time of the hour(s), the second arm is moved to a position where it can be engaged by the minute dial to move the first arm and thereby change the position of the valve plug component to the open position and/or closed position for the length of time set by the hour dial and the minute dial.
