A multiport rotary disc valve includes a valve housing having chamber walls that segregate an internal space of the housing into subchambers that each provide a portion of a fluid path through the valve housing. The valve includes a diverter assembly disposed in a cylindrical first subchamber, the diverter assembly controlling fluid flow through the valve housing. A second subchamber is disposed radially outward with respect to the first subchamber. In some rotational orientations of the diverter assembly, a fluid path between valve ports of the valve housing includes a first path portion that is disposed in the first subchamber and extends axially through the diverter assembly and a second path portion that is disposed in the second subchamber. The valve also includes seal assemblies disposed in housing so as to be aligned with the diverter assembly along a rotational axis of the diverter assembly.

A valve actuator may include a valve control shaft extending at least partially through a housing of the valve actuator, wherein the valve control shaft is configured for controlling a valve position of a diverter valve. A first cam wheel may be included, where the first am wheel at least partially surrounds the valve control shaft. A first cam may be fixed to the first cam wheel, and a first microswitch may have an actuator located in a rotational path of the first cam. The valve actuator may also include a second cam wheel at least partially surrounding the valve control shaft, where a second cam is fixed to the second cam wheel, and where a second microswitch has an actuator located in a rotational path of the second cam.

An apparatus for handling fluid within an at least partially electrically driven vehicle, with a valve device including a valve housing. The valve housing includes at least three two radially arranged port openings and at least one axially arranged port opening for the inflow and/or outflow of fluid, and a valve body which is arranged inside the valve housing and is configured to be rotatable about an axial axis of rotation R. The valve body includes a first connecting channel of arcuate shape for connecting two radially arranged port openings and a second connecting channel of arcuate shape for connecting a radially arranged port opening with an axially arranged port opening. The at least two radially arranged port openings define a base plane B, which is configured orthogonally to the axial axis of rotation R, and the first arcuate connecting channel defines a first connecting channel plane V.

A fluid management system includes a housing having a central manifold in fluid communication with a source of pressurized fluid, a plurality of first ports in communication with the central manifold, a plurality of second ports in communication with the environment surrounding the housing, and a plurality of third ports each configured to be coupled to a vessel for containing the pressurized fluid. The fluid management system also includes a plurality of valves and a plurality of actuators, each actuator including a smart material and associated with one of the plurality of valves. In response to activation by an energy source, each actuator is configured to move the associated valve to one of a first position or a second position.

A water separator valve assembly is provided, including: a main body, including a chamber, first and second outlet pipe and an inlet pipe; a control assembly, including a valve member disposed in the main body and an elastic plug, the valve member including a base disposed in the chamber and a receiving portion disposed on the base, the base including inlet holes respectively in communication with an inlet channel in the main body, the receiving portion including a receiving hole and a through hole, the elastic plug being disposed in the receiving hole, the elastic plug being elastically abutted between a bottom wall of the receiving hole and an inner wall the chamber; wherein the valve member is rotatable relative to the main body to drive the elastic plug to seal the first outlet channel or an second outlet channel in the main body.

An apparatus for handling fluid within an at least partially electrically powered vehicle, with a rotary sliding valve arrangement, including a setting element rotatably arranged about a central axis, a rotary sliding valve wall, the setting element is arranged within and rotatable relative to the rotary sliding valve wall, and the rotary sliding valve wall includes inlet and outlet openings arranged in a first plane and in a second plane.

A fluid injection system includes a valve device and a valve actuation device. The valve device has a valve member and a valve member coupling. The valve member has an open position that permits fluid to pass through and a closed position that prevents fluid from passing through. The valve member coupling is configured, when actuated, to transition the valve member between the open and closed positions. The valve actuation device having a valve actuation coupling and a drive mechanism. The valve actuation coupling is coupled to the valve member coupling and drive mechanism. The valve actuation coupling is movable independent of the drive mechanism to couple the valve actuation coupling to the valve member coupling. And, the valve actuation coupling is movable with the drive mechanism to actuate the valve member coupling to transition the valve member between the open and closed positions.
