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).
