A throttle valve assembly is provided, including a throttle valve housing (300) having a bore (310) therethrough and a throttle valve plug assembly (320). The throttle valve plug assembly includes a shaft (350) rotatably mounted on the throttle valve housing and a throttle valve plug (360) having a concave cut-out portion (370). The throttle valve plug is mounted on the shaft within the throttle valve housing and substantially perpendicular to the bore. The throttle valve plug has at least two fully open positions and a closed position. L'invention concerne un ensemble robinet d'étranglement, comprenant un boîtier (300) de robinet d'étranglement pourvu d'un alésage (310), et un ensemble (320) soupape de robinet d'étranglement. Cet ensemble soupape de robinet d'étranglement comprend un arbre (350) monté de manière rotative sur ledit boîtier de robinet d'étranglement, ainsi qu'une soupape (360) de robinet d'étranglement présentant une partie concave découpée (370). Cette soupape de robinet d'étranglement est montée sur l'arbre à l'intérieur dudit boîtier de robinet d'étranglement, afin d'être sensiblement perpendiculaire audit alésage. La soupape de robinet d'étranglement peut en outre adopter deux positions d'ouverture complète, ainsi qu'une position fermée.
