Abstract
A manifold has a frame and a plurality of valves supported by the frame, each valve having a cross gear that includes four semicircular recesses and four arms that terminate in pointed tips, and wherein the tips are non-jamming rubber tips. 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.
Claims21
A manifold comprising:
- a frame;
- a plurality of valves supported by the frame, each valve having a cross gear;
- a screw drive;
- a splined rotatable shaft parallel to the screw drive;
- and
- a slider driven by the screw drive over the splined rotatable shaft, the slider comprising an actuator that protrudes from the slider in response to rotation of the splined rotatable shaft to thereby engage one of the cross gears to actuate a respective one of the plurality of valves, wherein each cross gear has four semicircular recesses and four arms that terminate in pointed tips, and wherein the tips are non-jamming rubber tips.
A valve for a manifold, the valve comprising:
- an inlet;
- an outlet;
- a cross gear mounted to the valve;
- and
- a unitary cone-shaped plug having an integral stem, wherein the plug tapers outwardly in a direction away from the cross gear.
