(FR) ENSEMBLE VALVE
Abstract
(EN) - 43 - Abstract Valve assembly A valve assembly (1, 12, 21, 31, 44, 52, 60) includes a hollow tube (2). The valve assembly (1, 12, 21, 31, 44, 52, 60) also includes a first set of one or more valves (3) 5 arranged within the hollow tube (2). The first set of valves (3) is configured to permit sliding passage of a substantially cylindrical object (4). The valve assembly (1, 12, 21, 31, 44, 52, 60) also includes a second set of valves (5) arranged within the hollow tube (2) and spaced apart from the first set of valves to (3) define a chamber. The second set of valves (5) are configured to permit sliding passage of the cylindrical object (4). The 10 valve assembly (1, 12, 21, 31, 44, 52, 60) also includes one or more ultraviolet light sources (10) within the chamber (6) and/or a first port (13) connecting the chamber (6) to the exterior of the hollow tube (2) and configured for connection to a fluid flow path (14) for supply and/or extraction of fluid (19). 15 (Figure 2)
(FR) Un ensemble valve (1, 12, 21, 31, 44, 52, 60) comprend un tube creux (2). L'ensemble valve (1, 12, 21, 31, 44, 52, 60) comprend également un premier ensemble d'une ou plusieurs valves (3, 5) disposées dans le tube creux (2). Le premier ensemble de valves (3) est conçu pour permettre le passage coulissant d'un objet sensiblement cylindrique (4). L'ensemble valve (1, 12, 21, 31, 44, 52, 60) comprend également un second ensemble de valves (5) disposées à l'intérieur du tube creux (2) et espacé du premier ensemble de valves (3) pour définir une chambre. Le second ensemble de valves (5) est conçu pour permettre le passage coulissant de l'objet cylindrique (4). L'ensemble valve (1, 12, 21, 31, 44, 52, 60) comprend également une ou plusieurs sources de lumière ultraviolette (10) à l'intérieur de la chambre (6) et/ou un premier orifice (13) reliant la chambre (6) à l'extérieur du tube creux (2) et conçu pour être relié à une voie d'écoulement de fluide (14) pour l'alimentation et/ou l'extraction de fluide (19). 15 (Figure 2)
