Abstract[English]
A curtain chamber includes an orifice plate defining an orifice plate bore. A curtain plate is disposed adjacent to the orifice plate and defines a curtain plate bore. The orifice plate bore is disposed adjacent the curtain plate bore. A biasing element includes a first portion disposed in the orifice plate bore and a second portion disposed in the curtain plate bore. The biasing element biases the curtain plate towards the orifice plate. A race is defined by at least one of the orifice plate and the curtain plate. The race defines a race depth. A seal is disposed in the race. The seal includes an uncompressed seal depth greater than the race depth and a compressed seal depth less than the uncompressed seal depth.[French]
Une chambre rideau comprend une plaque d'orifice délimitant un alésage de plaque d'orifice. Une plaque de rideau est disposée adjacente à la plaque d'orifice et délimite un alésage de plaque de rideau. L'alésage de plaque d'orifice est ménagé de manière adjacente à l'alésage de plaque de rideau. Un élément de sollicitation comprend une première partie disposée dans l'alésage de plaque d'orifice et une seconde partie disposée dans l'alésage de plaque de rideau. L'élément de sollicitation sollicite la plaque de rideau vers la plaque d'orifice. Une bague de roulement est délimitée par au moins l'une parmi la plaque d'orifice et la plaque de rideau. La bague de roulement définit une profondeur de course. Un joint d'étanchéité est disposé dans la bague de roulement. Le joint d'étanchéité comprend une profondeur d'étanchéité non comprimée supérieure à la profondeur de course et une profondeur d'étanchéité comprimée inférieure à la profondeur d'étanchéité non comprimée.
