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.
Claims28
A multi-way valve comprising
- a valve housing coupled to a manifold of thermal fluid circuits, the valve housing including a valve housing body, a first housing end cover coupled to a first end of the valve housing body, and a second housing end cover coupled to a second end of the valve housing spaced apart axially from the first end of the valve housing relative to a valve axis, 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 that open into the first and second valve cavities, the first housing end cover coupled to the first end of the valve housing to close a first end opening to the first valve cavity, and the second housing end cover coupled to the second end of the valve housing to close a second end opening to the second valve cavity, and
- a valve flow controller includes a first valve rotor arranged in the first valve cavity of the valve housing body and a second valve rotor arranged in the second valve cavity of the valve housing body, the first and second valve rotors configured to rotate relative to the valve housing body about the valve axis, and 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 valve axis to a plurality of different predetermined positions to control a flow of fluid through the valve housing,
- wherein the valve housing body includes an annular outer wall that extends around the valve axis to define a hollow space, a partition wall located in the hollow space of the annular outer wall to divide the hollow space into the first valve cavity and the second valve cavity, and a housing base that extends from the annular outer wall and formed to define the plurality of apertures, and wherein the partition wall is formed to include a connecting aperture in fluid communication with the first valve cavity and the second valve cavity of the valve housing body.
A multi-way valve comprising:
- a valve housing coupled to a manifold of thermal fluid circuits, the valve housing including a valve housing body, a first housing end cover coupled to a first end of the valve housing body, and a second housing end cover coupled to a second end of the valve housing spaced apart axially from the first end of the valve housing relative to a valve axis, 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 that open into the first and second valve cavities, the first housing end cover coupled to the first end of the valve housing to close a first end opening to the first valve cavity, and the second housing end cover coupled to the second end of the valve housing to close a second end opening to the second valve cavity, and
- a valve flow controller includes a first valve rotor arranged in the first valve cavity of the valve housing body and a second valve rotor arranged in the second valve cavity of the valve housing body, the first and second valve rotors configured to rotate relative to the valve housing body about the valve axis, and 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 valve axis to a plurality of different predetermined positions to control a flow of fluid through the valve housing,
- wherein the second valve rotor includes a second valve rotor plate and a plurality of second valve rotor walls that extend axially away from the second valve rotor plate and spaced apart circumferentially to define a plurality of second valve ports, and wherein the second valve rotor plate is formed to include a second rotor through hole that extends axially through the second valve rotor relative to the valve axis so that the flow of fluid is able to flow axially through the second valve rotor parallel to 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 first valve cavity and a second valve cavity in fluid communication with the first valve cavity,
- a valve flow controller includes a first valve rotor arranged in the first valve cavity of the valve housing and a second valve rotor arranged in the second valve cavity of the valve housing, the first and second valve rotors configured to rotate relative to the valve housing about the valve axis, and 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 valve axis to a plurality of different predetermined positions to control a flow of fluid through the valve housing, and
- a first sealing system configured to seal between the first valve rotor and the valve housing in the first valve cavity, the first sealing system including a first seal located radially between the first valve rotor and the valve housing that extends circumferentially at least partway about the valve axis and a first biasing assembly configured to selectively apply a radial force on the first valve rotor to urge the first valve rotor into engagement with the first seal when the first valve rotor is in one of the plurality of different predetermined positions to improve sealing between the first valve rotor and the valve housing.
