Definitions

  • Fluid systems include sources of fluid (e.g., pumps), actuators, fluid lines connecting various components, reservoirs, valves, etc.
  • a valve is a device that regulates, directs, or controls the flow of a fluid (gases or liquids) by opening, closing, or partially obstructing various passageways.

  • Each valve may have a valve actuator (e.g., a solenoid coil) to actuate the valve, where electric wires or cables connect each valve actuator to a controller.
  • Valves are fluidly coupled to other components via fluid lines (tubes, pipes, hoses, etc.). Such configuration can reduce reliability in a fluid system due to the complexity of having many fluid lines and wires connecting various valves and components.
  • valve that operates as a central valving unit directing fluid between multiple fluid circuits or multiple components, rather than having a plurality of valves, each with a respective actuator and with fluid lines connecting the valves throughout the system. It is with respect to these and other considerations that the disclosure made herein is presented.
  • the present disclosure describes a valve.
  • the valve includes: an inlet manifold having an inlet port; a valve body having a plurality of outlet ports and a respective plurality of holes configured to communicate fluid to the plurality of outlet ports; a rotatable disk having disk holes; and a rotary actuator configured to rotate the rotatable disk, thereby selectively aligning one or more of the disk holes of the rotatable disk with one or more holes of the respective plurality of holes of the valve body to selectively provide fluid flow from the inlet port to one or more outlet ports of the plurality of outlet ports of the valve body.

  • Figure 19 is a flowchart of a method for operating a valve, in accordance with an example implementation.
  • An example fluid system may include several subsystems or circuits.
  • Valves can be used to selectively fluidly connect various components or circuits when desirable. For example, under some conditions, it may be desirable to operate two circuits in series and in other conditions it may be desirable to operate two circuits in parallel. In some cases, it may be desirable to fluidly connect two circuits to exchange fluid flow therebetween, while in other cases, it may be desirable to isolate the two circuits from each other.
  • Such selective connecting between various circuits of a fluid system can be implemented using a plurality of valves.
  • having a plurality of valves distributed throughout a system may involve running wires and fluid lines throughout the system, thereby increasing the likelihood of failure and reducing the reliability of the system. It may thus be desirable to have a single valve performing the operations of the plurality of valves. In an example, it may further be desirable to have a single actuator operating the valve rather than multiple actuators. This way, several fluid lines can be eliminated, and one actuation signal from a controller via a single cable can actuate the valve rather than having several actuators and wires distributed throughout the system.
