Multi-port valve assembly

An apparatus, comprising:

• a multi-port valve assembly, including:
• a housing;
• a plurality of ports, each of the plurality of ports formed as part of the housing;
• a rotor disposed in the housing, and the rotor rotatable about an axis, the rotor selectively in fluid communication with at least one of the plurality of ports;
• at least one seal having an inner radius and an outer radius, the at least one seal located in the housing such that the at least one seal is in sliding contact with the rotor;
• a plurality of channels integrally formed as part of the rotor, the plurality of channels further comprising;
• a first channel integrally formed as part of the rotor, the first channel further comprising:
• a first aperture, the first aperture extends through a body portion of the rotor perpendicular to the axis;
• an intermediate aperture in fluid communication with the first aperture, the intermediate aperture extends through the body portion of the rotor parallel to and offset from the axis;
• a second aperture in fluid communication with the intermediate aperture, the intermediate aperture extends between the first aperture and the second aperture, the intermediate aperture has a smaller cross-sectional area compared to the first aperture and the second aperture, and the first aperture is perpendicular to the intermediate aperture and the second aperture;
• a second channel integrally formed as part of the rotor such that the second channel is substantially straight and extends through the rotor in between the first channel and the third channel, the second channel further comprising:
• at least one arcuate surface having a radius which is less than or equal to the inner radius of the at least one seal;
• at least one side arcuate surface having a radius which is equal to or greater than the outer radius of the at least one seal;
• at least one outer area;
• and
• a middle area having a narrower width than the at least one outer area;
• a third channel integrally formed as part of the rotor, and the first channel, the second channel, and the third channel being fluidically isolated from one another;
• an outer wall extending away from the body portion of the rotor in a direction parallel to the axis, the second aperture extending through the outer wall;
• at least two flow paths formed by the orientation of the rotor relative to the housing and the plurality of ports;
• wherein the rotor is placed in one of a plurality of configurations relative to the plurality of ports and the housing such that each of the plurality of configurations includes the at least two flow paths using two of the plurality of channels, and fluid passes through at least one of the plurality of ports and the at least one seal when the rotor is placed in one of the plurality of configurations.
