An actuator and a method of controlling the actuator are disclosed. In one embodiment, the actuator is a valve (18) comprising a first port (26) and a second port (28) fluidly connected with the first port such that fluid communicates between the first port and the second port. A flexible member (22) is operatively connected with the first port and the second port. The flexible member is movable between a first position permitting fluid communication between the first port and the second port and a second position reducing fluid communication between the first port and the second port. A first controller (36) is operatively connected with the flexible member for moving the flexible member between the first position and the second position. A second controller (44A) is operatively connected with the flexible member for retaining the flexible member in the second position.
Cette invention concerne un actionneur et un procédé de commande dudit actionneur. Selon une réalisation, l'actionneur est une soupape (18) comportant un premier orifice (26) et un second orifice (28) en communication fluidique avec ledit premier orifice de telle sorte qu'un fluide peut s'écouler entre le premier et le second orifice. Un élément flexible (22) est relié fonctionnellement au premier orifice et au second orifice. Cet élément flexible peut se déplacer entre une première position autorisant la communication fluidique entre les premier et second orifices, et une seconde position réduisant la circulation de fluide entre les premier et second orifices. Un premier organe de commande (36) est relié fonctionnellement à l'élément flexible de façon à déplacer l'élément flexible entre la première position et la seconde position. Un second organe de commande (44A) est relié fonctionnellement à l'élément flexible de façon à retenir l'élément flexible dans la seconde position.
