  • Patent number: 11409310
    Abstract: A unit for the regulation for control of a fluid pressure, having at least one housing section and a switching film connected to the at least one housing section. A chemically inert, non-rubber-like PTFEswitching film switching film is disposed in the valve housing and switches at pressure differences of 1 mbar to 250 mbar for regulating, opening or blocking a flow of a fluid from the inlet to the outlet. The switching film is formed of a fluorine and carbon containing polymer material. The switching film has a plate-shaped flat body with a bending region and has a central closure region surrounded by the bending region. The bending region, when switching the switching film, moves the central closure region relative to a valve seat of the valve housing in an axial direction of the plate-shaped flat body toward or away from the valve seat by a stretch free or low-stretch bending movement.

  • Patent number: 11169549
    Abstract: A unit (10) for the regulation or control of a fluid pressure, having at least one housing section (13, 14) and a switching film (22) connected to the at least one housing section (13, 14) for switching at pressure differentials relative to an ambient pressure acting on the switching film (22), and for the regulation, release or blocking of a flow of the fluid between an inlet (28) and a discharge (30) for the fluid. The switching film (22) is made out of a polymer material having fluorine and carbon, in particular a thermoplastic having fluorine and carbon. In this arrangement, a hole cross-section (40) of the at least one housing section (13, 14) is closed off by the switching film (22).
