A cross-section of the actuator is smaller than a cross-section of the inner cavity.

There is provided a multi-directional selector valve which makes it possible to control opening and closing of the discharge ports in an easy manner and to minimize increase in cost and size even if the number of branches is increased. The multi-directional selector valve includes a valve case provided with a suction port and at least two discharge ports, at least two valve bodies provided for opening or closing the at least two discharge ports, a drive body formed into a rod-like shape and provided for driving the valve bodies and a drive source for rotating the drive body, and is configured such that any of convex portions provided on the side of the drive body are pressed onto any of the at least two valve bodies by the rotation of the drive body, thereby opening or closing the at least two discharge port in order.

A thermal management control valve a housing assembly having a first housing section and a second housing section, a rotary actuator coupled to a drive shaft, and a louver plate assembly. The louver plate assembly includes a louver plate having a louver cutout, a first seal assembly arranged between the louver plate and the first housing section, and a second seal assembly arranged between the louver plate and the second housing section. The first seal assembly includes a plurality of inner walls that define a plurality of first fluid passageways. The second seal assembly defines a second fluid passageway between. Selective rotation of the louver plate rotationally aligns the louver cutout with one or more of the plurality of first fluid passageways and the second fluid passageway to provide fluid communication between the one or more of the plurality of first fluid passageways and the second fluid passageway.

A washing apparatus, a switching device and a control method of the washing apparatus, the washing apparatus comprising: a box (10); a water cylinder (100) arranged inside the box (10); a filter device (600) having a water inlet (6101) and a filtered water outlet (6102) respectively connected to the water cylinder (100); a switching device (800) for controlling the water cylinder (100) and an external drainage pipeline (250) of the washing apparatus to be connected to the filtered water outlet (6102) of the filter device (600), the external drainage pipeline (250) being used to drain water to the outside of the washing apparatus; a cylinder wall (104) of the water cylinder (100), a top wall (11) of the box (10), and a side wall of the box (10) together forming an installation space extending from the cylinder mouth (103) of the water cylinder to the cylinder bottom, and the switching device (800) is arranged in the installation space. The switching device (800) is arranged in an installation space formed between the water cylinder (100) and the box (10), which is approximately in the shape of a triangular prism, so that the internal structure of the washing apparatus box (10) is compact, which is conducive to reducing the volume of the entire washing apparatus.

A multi-valve water treatment system may include a motor having an output shaft, a driven shaft fixed to the output shaft and having a cam disposed at an axial position along the driven shaft, and a valve assembly. The valve assembly may include a valve actuator urged into engagement with the driven shaft at the axial position, a fluid flow housing having a fluid outlet and at least one fluid inlet selectively sealingly engaged by the valve actuator to define a valve configured to selectively allow a flow of fluid from the fluid inlet toward the fluid outlet depending on the relative positions of the driven shaft and the valve actuator; and a diaphragm sealingly isolating the fluid inlet of the fluid flow housing from the valve actuator.

Provided is a series-connection type servo valve mechanism. The mechanism includes: a drive motor, a first valve seat, and a second valve seat, a first guide block, a first eccentric wheel, a second guide block, a second eccentric wheel, a first eccentric shaft, a second eccentric shaft, a first valve core seat, a second valve core seat, a first valve core, a second valve core, a first valve rod, a second valve rod, a first valve core plug, and a second valve core plug. The first guide block is capable of driving the first valve core plug through the first valve rod to move and cooperating with the first valve core to open or close an internal channel of the first valve core seat.

A cam-driven valve assembly includes a valve housing that defines a plurality of fluid passageways and supports an array of sliding-gate fluid valves in the fluid passageways to control the flow of fluid therethrough. The assembly includes a plurality of cams supported on a cam shaft. The cam shaft is arranged so that each cam is associated with a corresponding sliding-gate valve. Rotation of the cam shaft results in actuation of the valves via the cams. Each cam includes a pair of cam disks that cooperate to define an internal cam track. A movable plate of each fluid valve includes a cam follower that is received in the cam track of a corresponding cam. The cam tracks may be configured such that at least one of the sliding gate valves is actuated at time that is different relative to an actuation time of another sliding gate valve.
