A valve assembly for select distributed discharge of received fluid in a predetermined manner is generally provided. The assembly includes a manifold and a rotatable valve body. The manifold has an internal chamber, a fluid ingress passage for receipt of fluid, and a plurality of fluid discharge conduits. The fluid ingress passage and fluid discharge conduits are in fluid communication with the internal chamber. A first internal chamber section is characterized by the fluid ingress passage with a second internal chamber section characterized by ingress portions of the fluid discharge conduits. The valve body is adapted to be sealingly seated within the internal chamber so as to fluidly isolate the internal chamber sections, and includes a bore axially extending inwardly from a first end thereof for receipt of fluid from the fluid ingress port of the manifold, and a fluid egress passage in fluid communication with the bore for passage of received fluid to a select fluid discharge conduit of the fluid discharge conduits.

A valve device comprises a valve member, a housing, a first seal, and a second seal. The valve member includes a shaft portion rotatable about a rotation axis and a rotor connected to an end of the shaft portion in a first direction along the rotation axis, and, on an outer circumferential surface of the rotor there is a first flow path having a first opening. The housing includes an accommodating portion for accommodating the valve member, and a second flow path having a second opening communicable with the first opening, the accommodating portion having on its inner circumferential surface the second opening. A first seal is disposed between an outer circumferential surface of the rotor and an inner circumferential surface of the accommodating portion. The rotor includes a first region on which a coolant pressure acts in the first direction within the accommodating portion, and a second region on which the coolant pressure acts in a second direction opposite to the first direction, and a first area of the first region is below a second area of the second region.

A cartridge valve intended to be mounted in a suitable housing arranged in a receiving frame includes a chassis, a plug rotatably mounted on the chassis and comprising: a main body provided with fluid passages opening into an outer axial wall of the main body via at least two outlet ports, and a drive shaft capable of being coupled to an actuator to control the rotation of the plug, a peripheral axial wall assembly which is integral with the chassis, the peripheral axial wall assembly being provided with a plurality of radial openings intended to be aligned inwardly with outlet ports of the plug, in determined angular positions of the plug, and outwardly with associated ducts of the receiving frame.
