Abstract: Embodiments of a multi-port multi-mode valve are provided. The multi-port multi-plane valve includes a housing which defines an internal cavity. The housing further includes a plurality of ports, including two inlet ports and four outlet ports. Each of the plurality of ports is in communication with the internal cavity. A shell body is rotatably disposed within the internal cavity and provides selectable fluid communications between the ports. A seal member is also provided which has a plurality of openings and surrounds the shell body. Six modes of operation are provided by rotation of the shell body.

Abstract: A multiport valve has a plurality of inlets and outlets with selected positions to selectively direct fluid differently through the valve based on the position of the valve. A cylindrical exterior stemshell rotates internal to a housing to position channels and/or bores to provide the desired flow paths. Some flow paths are channels which extend linearly from one port to another, whether formed into an exterior surface, parallel to an axis of rotation of the stemshell, or pass from an inlet to an outlet in the exterior surface of the stemshell, preferably separated from flow from flow to an internal passage, which is preferably colinear with the axis of rotation, for at least some embodiments.

Abstract: A fluid manifold for cooling systems has parallel inlets directing flow through a base of a nozzle to an outlet which is preferably parallel to the inlets. The pressure drop from the inlets to the outlet is preferably less than 3 psi and the inlets have inlet portions with check valves connected thereto.
