Valve arrangement for controlling flow of fluid between two fluid chambers and writing implement provided therewith

摘要

The invention concerns a valve arrangement for controlling a flow of fluid between a first and a second fluid chamber, the arrangement being provided with: an elastomer material hose part (2), the outer side of whose wall is in contact with the first fluid chamber (5') and whose lumen (6) is connected to the second fluid chamber (9); one or a plurality of continuous slots (11) in the wall of the hose part (2), which slots, in the non-deformed state of the hose part (2), are closed owing to the inherent restoring force of the elastomer material and can be opened by deforming the hose part (2); and, disposed on the hose part (2), an actuating part (10) by means of which the hose part (2) can be deformed to control the flow of fluid through the slots (11). A valve arrangement of this type can be used, for example, in a recording implement.
