Abstract
The system opens and closes an n×m array of liquid pathways using n+m valves. The pathways (2) run from top to bottom of a body (1). Control bars (4), also with liquid pathways (2), are inserted in channels (3). These are movable by a power source. The liquid pathways are opened to pass liquid when the pathways in the body and the control bars are aligned with each other.
Claims14
A matrix multiple valve system in which opening and closing of (n×m) array, n and m along X- and Y-axes, respectively, of liquid pathways can be controlled through (n+m) of operating valves-along the X- and Y-axes, which comprises:
- a body in which (n×m) array of liquid pathways are positioned to run through the top and the bottom of the body;
- means for controlling liquid pathways of the body;
- channels in which the means for controlling liquid pathways of the body is positioned;
- and,
- a power source which is connected to the means for controlling liquid pathways of the body,
- whereby the liquid pathways are opened to pass liquid therethrough, in case the liquid pathways on the body and the channels are aligned with each other to reach ‘AND’ state logically.
