A module for a fluid circuit of a vehicle includes a unitary housing. The unitary housing of the module contains a fluid moving device, a fluid control device, and a power sharing connection. The power sharing device is configured to provide power to the fluid moving device and the fluid control device.

A control valve according to the present invention is configured such that when a third opening part, which is an auxiliary opening part, and a third discharge opening, which is an auxiliary connection opening, do not overlap, the third opening part and a continuous discharge opening overlap. Thus, for example, when a flow rate of cooling water for continuous circulation is required, such as during a cold start, cooling water guided through an internal passage is discharged via the continuous discharge opening in addition to cooling water guided from a bypass passage, thereby ensuring a sufficient flow rate of cooling water for continuous circulation.

A multi-passage coolant valve may include an outer housing including an outer body formed with a first outer inlet, a second outer inlet, a first outer outlet, and a second outer outlet, and an auxiliary body formed with a third outer outlet, and an inner housing rotatably provided in the outer housing. As the inner housing rotates by a predetermined angle, the first outer inlet and the first outer outlet are fluidly communicated with each other, the first outer inlet and the second outer outlet communicate with each other, and the second outer inlet and the third outer outlet communicate with each other.

A second temperature adjustment medium branches and flows into the first branch flow path and the second branch flow path at the branching portion, the second temperature adjustment medium and the second temperature adjustment medium are merged at the merging portion and flow through the pressure feed flow path to be supplied to the first pump, and the second temperature adjustment medium circulates through the second temperature adjustment circuit. A valve device configured to adjust a flow rate of the second temperature adjustment medium flowing through the second branch flow path is provided in the second branch flow path between the branching portion and the heat exchanger. The control device is configured to control the valve device to block the second temperature adjustment medium from flowing through the second branch flow path when a failure of the heat exchanger is detected.

A control valve includes: a second inner circumferential portion capable of holding a first spring, in a first communication passage provided at a first discharge opening of a housing; and a recessed portion recessed in a radial direction, at a position that is a part of a region in a circumferential direction of the second circumferential portion and overlaps a second communication passage opening in a biasing direction of the first spring. Therefore, when inserting the first spring into the first communication passage, it is possible to hold the first spring with the inner circumferential surface of the second inner circumferential portion. Consequently, the first spring is appropriately mounted in the second circumferential portion, thereby preventing a mounting defect of the first spring.

A multi-valve for a cooling system of a motor vehicle includes: a valve housing, which has a plurality of inlets and a plurality of outlets and delimits a cylindrical valve chamber, the plurality of inlets and the plurality of outlets opening into the cylindrical valve chamber; and a valve unit, which is arranged inside the cylindrical valve chamber of the valve housing and is rotatable about an axis of rotation between a plurality of switching positions by an actuator. Depending on a switching position of the valve unit, different inlets of the plurality of inlets are fluidically connectable to different outlets of the plurality of outlets. The valve unit has a plurality of fluid channel structures which are offset from one another in a circumferential direction. Each switching position of the plurality of switching positions is respectively assigned a fluid channel structure of the plurality of fluid channel structures.

A valve unit includes an actuator, a first valve and a second valve. The first/second valve includes a first/second valve housing and a first/second valve body. The first/second valve body is rotatably arranged in the first/second valve housing. The two valves are arranged coaxially to one another and rotatable about a common adjusting axis. The actuator is non-releasably coupled to the first valve body and releasably coupled to the second valve body via the first valve body. The first valve body is rotatable in a first and second direction of rotation with the actuator. The second valve body in the coupled state is co-rotatable with the first valve body in the first/second direction of rotation and in the decoupled state is not co-rotatable with the first valve body at least in the second direction of rotation. In addition, a method for adjusting the valve unit is provided.

A component housing unit for a vehicle thermal management system is configured for attachment to an exterior surface of an expansion tank having an interior surface defining an interior volume. The component housing unit is configured for connection to a first thermal control loop and a second thermal control loop. The component housing unit is configured for connecting the interior volume of the expansion tank to the first thermal control loop and the second thermal control loop respectively. The component housing unit includes a first component interface configured for direct attachment of a first system component connected to the first thermal control loop, and a second component interface configured for direct attachment of a second system component connected to the second thermal control loop.

Methods and systems are provided for a flow controller for an engine cooling system is provided. The flow controller comprises a chamber for receiving coolant flowing through the engine cooling system; a first aperture for coolant to flow into or out of the chamber; a first valve for controlling the flow of coolant through the first aperture according to a pressure of the coolant to flow through the first aperture; a second outlet for coolant to flow into or out of the chamber; and a second valve for controlling the flow of coolant through the second outlet according to the pressure of the coolant to flow through the second aperture, wherein the first and second apertures are inlets, for coolant to flow into the chamber though the first and second apertures, or the first and second apertures are outlets, for coolant to flow out of the chamber though the first and second apertures.

A multi-way coolant valve and a heat pump system having the same include an external housing in which first, second and third external inlets and first, second and third external outlets are formed; and an internal housing provided rotatably inside the external housing to selectively fluidically-connect the first, second and third external inlets, and the first, second and third external outlets, and divided into two stages through which a coolant flows respectively, wherein as the internal housing rotates at a predetermined interval in a selected mode of the vehicle, the first external inlet selectively fluidically-communicates with the first external outlet, the second external outlet, or the third external outlet, the second external inlet selectively fluidically-communicates with the first external outlet or the second external outlet, and the third external inlet selectively fluidically-communicates with the first external outlet, the second external outlet, or the third external outlet.
