Abstract
A metering end-fitting (1) has a metering chamber (30) inside which a piston (24) is slidably mounted, the piston being mounted so as to be able to pass from a first position in which the metering chamber (30) has a maximum volume to a second position in which the metering chamber (30) has a minimum volume. The metering chamber has at least one inlet passage (16, 17) which is open when the piston (24) is in the first position and substantially closed when the piston (24) is in the second position, the piston (24) being coupled to a closure element (50) which, in the first position of the piston (24) substantially closes off at least one outlet passage (15) in the metering chamber (30) and frees the outlet passage (15) when the inlet passage (16, 17) is closed. The closure element (50) moves with a shorter travel than the travel of the piston (24).
