Plungers and plunger assemblies for a diaphragm-sealed valve are provided. Each plunger is adpted to be received in a passage of the valve body and includes a base member and an upper member having a longitudinal play in this passage with respect to the base member. A resilient middle element is provided between the upper and base member. The base member is connected to a plunger actuating mechanism within the valve body. Optionally, the upper member may be self-aligning within the passage. The plunger can be used to compensate for temperature variations experienced by the valve in use.
L'invention porte sur des pistons et des ensembles pistons pour une soupape à membrane détanchéité. Chaque piston est conçu pour être logé dans un passage du corps de la soupape et comprend un élément de base et un élément supérieur ayant un jeu longitudinal dans ce passage par rapport à l'élément de base. Un élément intermédiaire souple est disposé entre l'élément supérieur et l'élément de base. L'élément de base est relié à un mécanisme d'actionnement de piston à l'intérieur du corps de la soupape. Facultativement, l'élément supérieur peut être à alignement automatique à l'intérieur du passage. Le piston peut être utilisé pour compenser des variations de température subies par la soupape lors de l'utilisation.
