ABSTRACT:
Device for printers using pressurized fluid medium for recording characters on an information carrier. The device is formed with at least one buffer chamber placed in direct connection with a fluid chamber, which constitutes one side of a wall or plate provided with a discharge. The buffer chamber includes an elastic or at least flexible dividing wall between the fluid chamber and the buffer chamber. The buffer chamber has a relatively small volume and is closed and, in one embodiment, is such that it allows penetration or migration of gas molecules only through the dividing wall.
