Described herein is a fluid valve assembly includes a body that defines a fluid cavity. The body includes an inlet through which fluid enters the fluid cavity and an outlet from which fluid exits the fluid cavity. The fluid valve assembly includes at least one arm rotatably coupled to the body and positioned within the fluid cavity. Additionally, the fluid valve assembly includes a flap coupled to the at least one arm. The flap includes a domed portion and a flat portion extending radially outwardly away from the domed portion.

Fluid valve

An article of manufacture includes a first rotor having a first flow-through area that is more than 50% of a total first rotor flow area and a first ridged arc member, and a second rotor having a second flow-through area that is more than 50% of a total second rotor flow area and a second ridged arc member. The article further includes an upstream stator and a downstream stator, each stator having a co-extensive stator flow-through area and a co-extensive structural area. The article includes an actuator having an engagement gear between the ridged arc members, where a turn of the engagement gear moves the ridged arc members in opposing directions. The first rotor and second rotor are phased to be at a maximum closed at a first position of the engagement gear and a maximum open at a second position of the engagement gear.

Multi-rotor flow control valve

A valve system includes a conical valve body disposed in an engine gaseous fluid stream and having a first fluid passageway, where the conical valve body is a cone or a frustum of a cone. The system includes a fluid inlet conduit fluidly coupled to the conical valve body on an upstream side, a first fluid outlet conduit, and a second fluid outlet conduit. The first and second fluid outlet conduits are fluidly coupled to the conical valve body on a downstream side. The valve system includes a valve actuator operatively coupled to the conical valve body and that rotates the conical valve body, and a controller that provides a valve actuator command and thereby selectively flows the engine gaseous fluid stream through the first fluid outlet conduit and the second fluid outlet conduit.
