Disclosed are apparatuses for controlling the flow of fluids which comprise a plurality of identical nozzle means arranged in an axially symmetrical configuration on a stator means and defining a plurality of identical flow channels or passageways. Each nozzle means comprises a fixed-spacer member and an adjustable-segment member. The fixed-spacer members are sealably fixed to the stator and mandate that the fluid flows through the flow channels. The adjustable-segment members are slideably connected to the fixed-spacer members in an essentially sealing relationship. Adjustable-segment members are operable to move only in straight-line direction and are not permitted to move pivotally. Jar-free movement of the adjustable members is possible regardless of flow or pressure of fluid. An essentially constant angle of discharge is possible for all adjustable positions of the nozzle means thereby enabling a high operating efficiency of the apparatus over a wide range of operating conditions.

A fluid-handling rotary apparatus comprising: a plurality of identical nozzle means each of which comprises a fixed-spacer member and an adjustable-segment member; an outer cover plate; an inner cover plate; said fixed-spacer member being rigidly fastened to, and sandwiched in abutting relationship

A fluid-handling rotary apparatus comprising: a plurality of identical nozzle means each of which comprises a fixed-spacer member and an adjustable-segment member; an outer cover plate; an inner cover plate; said fixed-spacer member being rigidly fastened to, and sandwiched in abutting relationship between, said outer cover plate and said inner cover plate in such a manner that, when said apparatus is in use, essentially no flow of fluid occurs between a first surface of said fixed-spacer member which abuts said outer cover plate and between a second surface of said fixed-spacer member which abuts said inner cover plate; and a means for adjusting the position of said adjustable-segment member relative to said fixed-spacer member, such that said adjustable-segment member is movable in a straight-line direction, without any pivotal movement. The apparatus of claim 4, wherein said fixed-spacer member forms with a rotor an angle into-the-rotor for fluid to enter said rotor, and wherein said angle into-the-rotor remains essentially constant for all adjustable positions of said nozzle means thereby permitting said angle into-the-rotor to be predetermined for highest operating efficiency.
