Abstract

L'invention concerne une commande (10) comportant un corps (12), un piston (20) logé dans le corps, et une tige (28), le piston étant apte à se déplacer dans le corps sous l'effet de la tige et dans laquelle : - le piston (20) comprend une première partie cylindrique (20A) et une deuxième partie cylindrique (20B), le diamètre (D1) de la première partie cylindrique étant supérieur à celui (D2) de la deuxième partie cylindrique, la première partie cylindrique (20A) s'étend selon un premier axe (X1) et la deuxième partie cylindrique (20B) s'étend selon un deuxième axe (X2), le premier axe et le deuxième axe (X1, X2) étant parallèles et non confondus, le piston (20) étant apte à se déplacer dans le corps (12) en translation selon une direction (A) sensiblement parallèle aux premier et deuxième axes ; et - le corps (12) comportant un premier tronçon (12A) interagissant avec la première partie cylindrique (20A) du piston et un deuxième tronçon (12B) interagissant avec la deuxième partie cylindrique (20B) du piston ; - la tige (28) étant fixée à la première partie cylindrique (20A) du piston.The invention relates to a control (10) comprising a body (12), a piston (20) housed in the body, and a rod (28), the piston being able to move in the body under the effect of the rod. and wherein: - the piston (20) comprises a first cylindrical portion (20A) and a second cylindrical portion (20B), the diameter (D1) of the first cylindrical portion being greater than that (D2) of the second cylindrical portion, the first cylindrical portion (20A) extends along a first axis (X1) and the second cylindrical portion (20B) extends along a second axis (X2), the first axis and the second axis (X1, X2) being parallel and not confused, the piston (20) being able to move in the body (12) in translation along a direction (A) substantially parallel to the first and second axes; and - the body (12) having a first section (12A) interacting with the first cylindrical portion (20A) of the piston and a second section (12B) interacting with the second cylindrical portion (20B) of the piston; - The rod (28) being fixed to the first cylindrical portion (20A) of the piston.
