A manifold has a frame and a plurality of valves supported by the frame, each valve having a cross gear that includes four semicircular recesses and four arms that terminate in pointed tips, and wherein the tips are non-jamming rubber tips. The manifold also has a screw drive and a splined rotatable shaft parallel to the screw drive. The manifold further includes a slider driven by the screw drive over the splined rotatable shaft. The slider includes an actuator that protrudes from the slider to engage one of the cross gears to actuate a respective one of the plurality of valves.

A convenient switching valve includes a main body, a switching member and a positioning disc. The main body is provided with a water inlet and at least one water outlet. The positioning disc is rotatably fitted at an end of the main body. The positioning disc cooperates with the switching member, enabling the switching member to be moved in the main body to block a water passage between the water inlet and the water outlet. By rotating the positioning disc, the positioning disc movably press the switching member to block the water passage, thereby realizing the control of the water flow of the water outlet. The operation is convenient and labor-saving.

A control system for a coolant control valve unit, which includes a cam and a valve that opens and closes a coolant passage in conjunction with rotation of the cam, includes: a motor controlling the rotation of the cam; and a controller configured to correct a target valve opening degree of the valve using a correction value according to a degree of wear of the valve, to determine a target rotational angle of the cam using the target valve opening degree corrected by the correction value, and to control an operation of the motor according to the target rotational angle of the cam.

A multiport valve may use a magnetic sphere in a fluid flow path to block flow. A magnet external to the fluid flow path may cause the sphere to pull away from the blocked position and may permit flow. The magnet may be moved away from the sphere, causing the sphere to again block the flow. By arranging multiple ports along the path of a magnet, each port may be individually actuated with a single magnet. The magnet's position may be controlled by a motor, allowing for computer controlled selection of a valve to be actuated with a minimum of moving parts and leakage. Each sphere may seal against an o-ring or against a cone, and the magnet may be selected to overcome the pressure forces holding the sphere in the sealed position.

A directional flow control device includes a housing extending along a longitudinal axis between an inlet end and a discharge end. The housing holds stator magnets. The directional flow control device includes a flow deflector received in the housing. The flow deflector is rotatable in the housing about a rotation axis parallel to the longitudinal axis. The flow deflector has a flow channel therethrough. The flow channel has an intake bore at a front end of the flow deflector and a discharge bore at a rear end of the flow deflector. The intake bore is coaxial with the rotation axis. The discharge bore is offset from the rotation axis. The flow deflector has rotor magnets aligned with and facing the stator magnets. The stator magnets are energized to cause rotation of the flow deflector relative to the housing.

A refrigeration cycle device includes a pre-evaporator decompression unit that decompresses refrigerant which flowed out from an exterior heat exchanger, and an evaporator passage that guides the refrigerant which flowed out from the exterior heat exchanger to a suction port of a compressor while passing through a pre-evaporator decompression unit and an evaporator. Further, the refrigeration cycle device includes a bypass passage that guides the refrigerant which flowed out from the exterior heat exchanger to the suction port of the compressor while bypassing the pre-evaporator decompression unit and the evaporator, a pre-exterior device switching unit, and a passage switching unit that opens and closes the bypass passage. Further, the pre-exterior device switching unit and the passage switching unit form a coupled valve where the pre-exterior device switching unit and the passage switching unit are mechanically coupled.
