Abstract
A manifold has a frame and a plurality of valves supported by the frame, each valve having a cross gear. The manifold also has a screw drive and a splined rotatable shaft parallel to the screw drive. The manifold further includes a slider driven by the screw drive over the splined rotatable shaft. The slider includes an actuator that protrudes from the slider to engage one of the cross gears to actuate a respective one of the plurality of valves.
Claims20
A valve for a manifold, the valve comprising:
- a valve body having an inlet, an outlet and a central passageway between the inlet and outlet;
- a cross gear rotatably mounted to the valve body;
- a cone-shaped plug connected via a stem to the cross gear, wherein the cone-shaped plug tapers outwardly in a direction away from the cross gear;
- a cap attached to a bottom of the valve body to define a space containing a water volume between the plug and the cap;
- and
- a water diversion channel extending from the inlet to the space between the plug and the cap to divert water from the inlet to the space between the plug and the cap for exerting pressure on the cone-shaped plug in the valve to enable the plug to provide a fluid-tight seal.

A valve comprising:
- a valve body having a neck, an inlet, an outlet and a central water passageway between the inlet and outlet;
- a cross gear rotatably mounted via a stem to the valve body, wherein the stem extends through the neck;
- a frusto-conical plug connected via a stem to the cross gear, wherein the plug tapers outwardly in a direction away from the cross gear;
- a cap attached to a bottom of the valve body to define a space containing a water volume between the plug and the cap;
- and
- a water diversion channel extending from the inlet to the space between the plug and the cap to divert water from the inlet to the space between the plug and the cap for exerting pressure on the plug to enable the plug to provide a fluid-tight seal.
