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 a sealing system. The valve flow controller is arranged in the valve housing to control flow through the valve housing. The sealing system is configured to seal between the valve housing and the valve flow controller.
Claims20
A multi-way valve comprising
- a valve housing coupled to a manifold of thermal fluid circuits, the valve housing including a valve housing body and a housing cover coupled to the valve housing body, the valve housing body shaped to define a valve cavity and a plurality of apertures that open into the valve cavity, and the housing cover coupled to the valve housing to close a top opening to the valve cavity, and
- a valve flow controller including a valve rotor arranged in the valve cavity of the valve housing body and configured to rotate relative to the valve housing body about a valve axis and an actuator coupled to the valve rotor to drive rotation of the valve rotor about the valve axis, wherein the valve rotor cooperates with the valve housing to define a plurality of flow paths when the valve rotor is rotated about the valve axis to a plurality of different predetermined positions,
- wherein the valve rotor defines a first chamber that connects at least two apertures included in the plurality of apertures in fluid communication and a second chamber separate from the first chamber that connects at least two different apertures included in the plurality of apertures in fluid communication when the valve rotor is in any one of the plurality of different predetermined positions, and
- wherein one of the at least two apertures connected in fluid communication by the first chamber is a center aperture that extends axially through the valve housing body at the valve axis.

A multi-way valve comprising
- a valve housing that extends axially along a valve axis, the valve housing formed to include a valve cavity and a plurality of apertures that open into the valve cavity,
- a valve flow controller including a valve rotor arranged in the valve cavity of the valve housing and configured to rotate relative to the valve housing about the valve axis, wherein the valve rotor cooperates with the valve housing to define a plurality of flow paths when the valve rotor is rotated about the valve axis to a plurality of different predetermined positions,
- wherein the valve rotor defines a first chamber that connects at least two apertures included in the plurality of apertures in fluid communication and a second chamber separate from the first chamber that connects at least two different apertures included in the plurality of apertures in fluid communication, and
- wherein one of the at least two apertures connected in fluid communication by the first chamber is a center aperture that extends axially through the valve housing body at the valve axis.

A method comprising:
- providing a multi-way valve comprising:
- a valve housing that extends axially along a valve axis, the valve housing formed to include a valve cavity and a plurality of apertures that open into the valve cavity, and
- a valve flow controller including a valve rotor arranged in the valve cavity of the valve housing and configured to rotate relative to the valve housing about the valve axis, wherein the valve rotor defines a first chamber and a second chamber separate from the first chamber, and
- rotating the valve rotor about the valve axis to a first position in which the first chamber of the valve rotor connects a first aperture in fluid communication with a second aperture included in the plurality of apertures and the second chamber of the valve rotor connects a third aperture in fluid communication with a fourth aperture, wherein the first aperture extends axially through the valve housing at the valve axis.
