Abstract

A unit for regulating or controlling a fluid pressure of a fluid has a housing with at least one housing part and an inlet and an outlet for the fluid. A switching film is connected to the housing part and switches at pressure differences of 1 to 250 mbar relative to an ambient pressure acting on the switching film. The switching film regulates, releases or blocks a flow of the fluid between the inlet and the outlet for the fluid. The switching film is made of thermoplastic synthetic material. An opening cross section of the housing part is closed off by the switching film. In a method for fluid-tightly connecting a switching film to a housing part of the unit, a radial outwardly positioned joining region of the switching film is fluid-tightly pressed against the housing part in the region of joining surface.
