Abstract
(EN) An apparatus for controlling flow through a flow body (100) comprising an intake opening (102) and an output opening (108) in the flow body, a cavity with a first cross-sectional shape and an opening, a diaphragm (114) or a bellows, wherein the diaphragm or the bellows seals the opening of the cavity and the diaphragm or the bellows includes a hole, a plunger (106A) with the cross- sectional shape corresponding to the cavity, wherein the plunger is longitudinally movable within the cavity and a plunger portion (106B) forms an orifice with cavity portion, and a rod (104A) coupled with the plunger for facilitating the longitudinal movement of the plunger, wherein the rod comprises a rod cross section that corresponds to the hole in the diaphragm or the bellows.
(FR) Appareil pour régler l'écoulement à travers un corps d'écoulement (100) comprend une ouverture d'admission (102) et une ouverture de sortie (108) dans le corps d'écoulement, une cavité ayant une première forme de section transversale et une ouverture, un diaphragme (114) ou un soufflet, le diaphragme ou le soufflet fermant hermétiquement l'ouverture de la cavité et le diaphragme ou le soufflet comprenant un trou, un piston (106A) ayant la forme de section transversale correspondant à la cavité, le pisto étant mobile longitudinalement au sein de la cavité et une partie piston (106B) formant un orifice avec une partie cavité, et une tige (104A) accouplée au piston afin de faciliter le mouvement longitudinal du piston, la tige comprenant une section transversale de tige qui correspond au trou dans le diaphragme ou le soufflet.
