VALVE SYSTEM FOR A FLUID CHANNEL

摘要

The present invention relates to a valve system (5) connectable to a fluid channel (3), wherein the valve system (5) comprises an actuating means (33) and a closing element (17) for selectively closing and opening of the channel (3), wherein the valve system (5) comprises a chamber (15) anda movable coupling member (37), wherein at least one section of the coupling member (37) is located within the chamber (15) and the coupling member (37) is capable of moving under its gravitational force into a transfer position in which the coupling member (37) may transferto the closing element (17) an external force acting on the actuating means (33) towards the closing element (17).
