Abstract
A multi-way valve adapted to control a flow of fluid to different thermal fluid circuits includes a valve housing, a valve flow controller, and sealing systems. The valve flow controller is arranged in the valve housing to control flow through the valve housing. Each scaling system is configured to seal between the valve housing and one of the valve rotors included in the valve flow controller.

A multi-way valve comprising
- a valve housing including a valve housing body and a housing cover, the valve housing body shaped to define a first valve cavity, a second valve cavity in fluid communication with the first valve cavity, and a plurality of apertures in fluid communication with at least one of the first valve cavity and the second valve cavity, and the housing cover coupled to the valve housing body to close openings of the first and second valve cavities, and
- a valve flow controller including a first valve rotor arranged in the first valve cavity of the valve housing body and configured to rotate relative to the valve housing about a first rotor axis and a second valve rotor arranged in the second valve cavity of the valve housing body and configured to rotate relative to the valve housing about a second rotor axis, the first and second valve rotors cooperate to define a plurality of flow paths when the first and second valve rotors are rotated about the respective rotor axes to a plurality of different predetermined positions to control a flow of fluid through the valve housing,
- wherein the first valve rotor includes a first valve rotor body that extends circumferentially about the first rotor axis, a first valve rotor shaft that extends axially away from the first valve rotor body along the first rotor axis, and a first valve rotor cover coupled to the first valve rotor body for rotation therewith, wherein the first valve rotor body is formed to include a plurality of first rotor through holes that extend axially through the first valve rotor body relative to the first rotor axis and align with different apertures included in the plurality of apertures when the first valve rotor is in one of the plurality of different predetermined positions to allow the flow of fluid therethrough, and wherein the first valve rotor cover is formed to define at least one chamber that extends around adjacent first rotor through holes in the first valve rotor body when the first valve rotor cover is coupled to the first valve rotor body so as to interconnect the adjacent first rotor through holes in fluid communication with each other.
